[0098] The present application embodiment provides a measurement method. To better understand the measurement method provided by the present application embodiment, first combine Figure 1 The existing measurement process is described below. Figure 1It is a structural example diagram of an existing measurement system. The existing measurement system includes a bit error meter 101 and a measuring instrument 110 connected in sequence. The measuring instrument 110 specifically includes an optical splitter 102, a measuring optical fiber 103, an adjustable optical attenuator 104 and an eye pattern analyzer 106, and the measuring instrument 110 also includes an adjustable reflectometer 105 connected to the optical splitter 102. The photoelectric conversion module 111 to be measured is connected between the bit error meter 101 and the optical splitter 102 of the measuring instrument 110 as a device under test (DUT). During the measurement of the photoelectric conversion module 111 to be measured, the service rate, modulation format, amplitude or measurement pattern of the first measurement electrical signal of the bit error meter 101 are set according to the photoelectric conversion module 111 to be measured, and the first measurement electrical signal is sent to the photoelectric conversion module 111 to be measured, and the photoelectric conversion module 111 to be measured performs electrical-optical conversion on the first measurement electrical signal to obtain a measurement optical signal. The optical splitter 102 splits the measurement optical signal to obtain a first measurement optical signal and a second optical signal. The adjustable reflectometer 105 is used to adjust the return loss to a suitable range and reflect the third optical signal to the optical splitter according to the second optical signal. The optical splitter 102 superimposes the first measurement optical signal and the third optical signal to obtain a fourth electrical signal, and sends the fourth optical signal to the adjustable optical attenuator 104 through the measurement optical fiber 103. The adjustable attenuator 104 attenuates the fourth optical signal to a suitable range and inputs it to the eye pattern analyzer 106. The eye pattern analyzer 106 obtains a variety of performance indicators of the photoelectric conversion module 111 to be measured according to the fourth optical signal. The performance indicators are used to measure the performance of the photoelectric conversion module. For example, the performance indicator can be a transmitter dispersion eye closure cost (transmitter and dispersion eye closure for PAM4, TDECQ) indicator. The TDECQ indicator cannot reflect the impact of different situations of the photoelectric conversion module link on the performance indicator, so that the measured performance indicator cannot accurately reflect the quality of the photoelectric conversion module.

[0099] The measurement method provided in the embodiment of the present application is used to measure the photoelectric conversion module to obtain performance indicators, and the obtained performance indicators can reflect different conditions of the photoelectric conversion module link, so that the measured performance indicators can accurately reflect the quality of the photoelectric conversion module.

[0100] This embodiment does not limit the type of optoelectronic conversion module used in the measurement method. For example, the type of the optoelectronic conversion module may be a linear pluggable optical module (LPO), an on-board optical module (OBO) based on optical input & output (OIO) technology, a near package optical module (NPO) or a co-package optical module (CPO), etc. This example takes the optoelectronic conversion module used in the measurement method as LPO as an example. This example does not limit the packaging form of the optoelectronic conversion module, for example, small form pluggable (SFP), quad small form-factor pluggable (QSFP), double-density quad small form-factor pluggable (QSFP-DD), octal small formfactor pluggable (OSFP), centum form-factor pluggable (CFP) or chip-on-board packaging (COBO), etc.

[0101] Combination Figure 2 The structure of the photoelectric conversion module is described, wherein: Figure 2The first example structure example diagram of the optoelectronic conversion module provided in the present application. The optoelectronic conversion module shown in this example can also be referred to as an optical transceiver module or an optical module, etc. The optoelectronic conversion module 200 shown in this example specifically includes a transmission (transport, TX) channel 210 and a receiving (receive, RX) channel 220. The TX channel 210 includes a transmission channel compensation module 211, a driver 212 and an electro-optical conversion chip 213 connected in sequence. The transmission channel compensation module 211 includes a continuous time linear equalizer (CTLE). The TX channel 210 compensates the received first electrical signal through the CTLE to obtain a first compensated electrical signal. Different gears of the CTLE determine the frequency response (frequency response) of the first compensated electrical signal output from the CTLE, which can be referred to as a frequency response or a frequency response curve. The frequency response of an electrical signal refers to a curve of the gain of an electrical signal changing with frequency. The TX channel 210 can compensate for different insertion losses caused by the transmitted electrical signal through different gears of the CTLE. The transmission channel compensation module 211 sends the first compensated electrical signal to the driver 212, and the driver 212 amplifies the power of the first compensated electrical signal to obtain the first amplified electrical signal, and sends the first amplified electrical signal to the electro-optical conversion chip 213. The electro-optical conversion chip 213 performs electro-optical conversion on the electrical signal of the first amplified electrical signal to output a first optical signal. For example, the electro-optical conversion chip 213 can adopt a direct modulation laser (direct modulation laser, DML), an electro-absorption modulated laser (electro-absorption modulated laser, EML) or a vertical cavity surface emitting laser (vertical cavity surface emitting laser, VCSEL). For another example, the electro-optical conversion chip 213 can also adopt the structure of a laser and a modulator, and the modulator can be a Mach-Zehnder modulator (mach-zehnder modulator, MZM) or a micro ring modulator (miro ring modulator, MRM), etc.

[0102] The RX channel 220 includes an optoelectronic conversion chip 223, an amplifier 222, and a receiving channel compensation module 221 connected in sequence. The optoelectronic conversion chip 223 is used to receive a second optical signal, and perform optoelectronic conversion on the second optical signal to obtain a second electrical signal. The amplifier 222 is used to amplify the power of the second electrical signal from the optoelectronic conversion chip 223 to obtain an amplified second electrical signal, and send the amplified second electrical signal to the receiving channel compensation module 221. The receiving channel compensation module 221 compensates the amplified second electrical signal to obtain a compensated second electrical signal. Specifically, the receiving channel compensation module 221 may include a feed forward equalizer (FFE), which compensates the amplified second electrical signal to suppress inter-symbol interference (ISI). The FFE can be configured with multiple tap coefficients, and different tap coefficients of the FFE can compensate for different insertion losses caused by the transmission of electrical signals. The optoelectronic conversion chip 223 can be a photodiode (positive intrinsic-negative, PIN) or an avalanche photo diode (APD). The amplifier 222 may be a trans-impedance amplifier (TIA).

[0103] The photoelectric conversion module 200 further includes a control chip 230 connected to the transmission channel compensation module 211, the driver 212, the electro-optical conversion chip 213, the photoelectric conversion chip 223, the amplifier 222, and the receiving channel compensation module 221. The control chip 230 may be one or more chips, or one or more integrated circuits. For example, the control chip 230 may be one or more optical digital signal processors (oDSP), field-programmable gate arrays (FPGA), application specific integrated circuits (ASIC), system on chip (SoC), central processor unit (CPU), network processor (NP), microcontroller unit (MCU), programmable logic device (PLD), network card chip, storage interface chip or other integrated chip, or any combination of the above chips or processing modules. The control chip 230 is used to configure and control the photoelectric conversion module 200, obtain performance information and alarm information of the photoelectric conversion module 200, and exchange information with single boards, equipment, instruments, etc. through a communication bus.

[0104] It should be noted that the structure of the photoelectric conversion module 200 shown in this example is a single-channel transceiver module, which is not limited to this. For example, the photoelectric conversion module can also be a single-channel transmitter module, which only includes Figure 2 The TX channel shown. For another example, the optoelectronic conversion module may also be a single-channel receiving module, and the single-channel receiving module only includes the RX channel. For another example, the optoelectronic conversion module 200 may also be a multi-channel parallel transceiver module. The multi-channel parallel transceiver module includes multiple TX channels and multiple RX channels. This example does not limit the number of TX channels and the number of RX channels included in the optoelectronic conversion module. For another example, the optoelectronic conversion module may also be a single-fiber bidirectional module, and the single-fiber bidirectional module includes a TX channel and an RX channel. The single-fiber bidirectional module also includes a wavelength division multiplexing (WDM), and the WDM is connected to the TX channel and the RX channel, respectively. For another example, the optoelectronic conversion module may also be a wavelength division multiplexing transceiver module, and the wavelength division multiplexing transceiver module includes an RX channel and a TX channel. The wavelength division multiplexing transceiver module also includes a WDM connected to multiple TX channels and a WDM connected to multiple RX channels. For a description of the TX channel and RX channel shown in the above example, please refer to Figure 2 The corresponding instructions are not elaborated in detail.

[0105] This example does not limit the code type of the electrical signal input / output of the photoelectric conversion module, for example, not return to zero (NRZ), pulse amplitude modulation (PAM) 2, PAM4, PAM6, PAM8, phase shift keying (PSK), binary phase shift keying (BPSK), quadrature phase shift keying (QPSK) or quadrature amplitude modulation (QAM), etc.

[0106] Figure 3 310 and 330. The first embodiment of the measurement system provided in this application is a structural example diagram. The measurement system shown in this embodiment includes a first measurement device 310 and a first measurement instrument 330. For the description of the structure of the first measurement instrument 330 shown in this embodiment, please refer to Figure 1 The first measuring device 310 and the first measuring instrument 330 are connected to the TX channel 210 of the photoelectric conversion module 200 to be measured. For the structure of the TX channel 210 of the photoelectric conversion module 200, please refer to Figure 2 The corresponding description is not repeated here. For the description of the structure of the first measuring instrument 330, please refer to Figure 1 The corresponding description is not repeated in detail. Optionally, the first measuring device 310 shown in this embodiment also includes a communication channel for communicating with the photoelectric conversion module 200, and the first measuring device 310 configures the working parameters of the photoelectric conversion module 200 through the communication channel. For example, the communication channel is connected to the communication bus of the photoelectric conversion module 200. Optionally, the first measuring device 310 also includes a feedback channel connected to the first measuring instrument 330, and the first measuring device 310 receives the transmission performance index from the first measuring instrument 330 through the feedback channel. The first measuring device 310 can be automatically adjusted based on the transmission performance index from the first measuring instrument 330, thereby increasing the degree of automation of the execution process of the measurement method provided in the embodiment of the present application, reducing manual intervention, and improving measurement efficiency.

[0107] based on Figure 3 The measurement system shown, combined with Figure 4 The execution process of the measurement method provided in this embodiment is described as shown in FIG. Figure 4This is a flowchart of the execution steps of the first embodiment of the measurement method provided by the present application. The measurement method shown in this embodiment is used to measure the quality of the TX channel of the photoelectric conversion module.

[0108] Step 401: A first measuring device attenuates a first electrical signal according to a first transmission link parameter to obtain a second electrical signal.

[0109] The first measurement device shown in this embodiment generates a first electrical signal. Specifically, the first measurement device generates the first electrical signal according to pre-configured parameters, which may be service rate, modulation format, measurement pattern and other parameters, which are not specifically limited.

[0110] The first measuring device pre-stores a TX configuration list as shown in Table 1:

[0111] Table 1

[0112] Send link parameter 1 Send link parameter 2 Send link parameter 3 …… Send link parameter M

[0113] As shown in Table 1, the TX configuration list stored in the first measurement device includes M transmission link parameters, namely, transmission link parameter 1, transmission link parameter 2 to transmission link parameter M. M shown in this embodiment is a positive integer. This embodiment is illustrative using M as an arbitrary integer greater than or equal to 2 as an example.

[0114] When the photoelectric conversion module is used in a specific application, it is necessary to connect the device. For example, the photoelectric conversion module and the device can be an integrated device. For example, the device includes a pluggable single board, and the photoelectric conversion module can be pluggable and connected to the single board. This example does not limit the number of photoelectric conversion modules connected to the device. The device can be an optical transmission device, an optical access device, a router, a switch, a wireless base station, a wireless remote access device, a wireless baseband signal processing device, etc. It can also be a computing server (usually referred to as a server), a high performance computer (HPC), a storage server, or a memory resource pool. This example does not limit the type of device, as long as the device has an electro-optical conversion function and an optical interface that can be connected to an optical fiber. When the photoelectric conversion module is connected to the device, the TX channel of the device is used to send an electrical signal to the photoelectric conversion module, and the TX channel of the device will bring one or more effects such as certain insertion loss, crosstalk or reflection to the electrical signal. The first measuring device shown in this embodiment is used to simulate the influence of the TX channel of the device on the electrical signal. The specific simulation method can be that the first measuring device attenuates the amplitude of the first electrical signal according to the first transmission link parameter to obtain the second electrical signal. The first transmission link parameter is one of the M transmission link parameters shown in Table 1. For example, the first transmission link parameter is X decibels (dB). If the TX channel of the device will increase the insertion loss of X dB to the electrical signal to be sent to the optoelectronic conversion module, then, in order to realize the first measuring device simulating the insertion loss of the electrical signal transmitted by the TX channel of the device, the first measuring device reduces the amplitude of the first electrical signal according to the first transmission link parameter (i.e., reduces it by X dB). X is an arbitrary value greater than 0. It can be understood that the first measuring device attenuates the amplitude of the first electrical signal according to the first transmission link parameter, which is equivalent to the transmission of the first electrical signal through the TX channel of the device (the TX channel of the device increases the insertion loss of X dB to the first signal). It can be understood that the first measuring device simulates the different degrees of influence of the TX channel of the device on the electrical signal according to the transmission link parameters with different values ​​shown in Table 1.

[0115] This embodiment does not limit the value range of the M transmission link parameters stored in the first measurement device. For example, the M transmission link parameters take values ​​in the range of 3 to 16 dB. The description of the value range of the M transmission link parameters in this embodiment is an optional example and is not limited. For example, the value range of the M transmission link parameters is 1 to 25 dB or 5 to 11 dB. The value range of M can be 1 to 14, and the step size for adjusting the value of the transmission link parameter can be 1 dB. Then, when M=1, the transmission link parameter 1=3dB, and when M=2, the transmission link parameter 2=4dB, and so on. In specific applications, the step size for adjusting the value of the transmission link parameter can be any value in the range of 1 to 25 dB, and this example does not limit the value of the step size. The above example takes different step sizes as the same example. In other examples, different step sizes may also be different. For example, the M-1 step sizes used to obtain M transmission link parameters are 1dB, 1dB, 3dB, 3dB, 3dB, 1dB, 1dB, and so on. Then, the corresponding M transmission link parameters are 3dB, 4dB, 5dB, 8dB, 11dB, 14dB, 15dB, 16dB, and so on. This example can also be based on the most simplified example of transmission link parameters. For example, the value range of the M transmission link parameters shown in this example is between 1 and 25dB. Then, the first measurement device stores two transmission link parameters, and the two transmission link parameters are the maximum value (i.e., 25dB) and the minimum value (i.e., 1dB) between 1 and 25dB.

[0116] In this embodiment, the insertion loss of the electrical signal transmitted by the TX channel of the first measuring device according to the M transmission link parameters is used as an example. In other examples, the first measuring device may also simulate different link crosstalk values ​​of the TX channel of the device according to the M transmission link parameters, and then the value range of the M transmission link parameters may be between -50 and -35 dB. For another example, the first measuring device may also simulate different link reflection values ​​of the TX channel of the device according to the M transmission link parameters, and then the value range of the M transmission link parameters may be between -15 and -10 dB.

[0117] The M transmission link parameters may also be a combination of a series of insertion loss values, link crosstalk values, and link reflection values, such as an insertion loss value ranging from 1 to 25 dB, a link crosstalk value ranging from -50 to -35 dB, and a link reflection value ranging from -15 to -10 dB, wherein one transmission link parameter may be: an insertion loss value of 1 dB, a link crosstalk value of -50 dB, and a link reflection value of -15 dB;

[0118] Step 402: The first measuring device sends a second electrical signal to the photoelectric conversion module.

[0119] Specifically, the first measuring device sends the second electrical signal to the TX channel of the photoelectric conversion module 200 .

[0120] Step 403: The photoelectric conversion module sends a first measuring light signal to the first measuring instrument.

[0121] First, the photoelectric conversion module converts the second electrical signal from the first measuring device into a first measuring optical signal. For an explanation of the process of the TX channel 210 of the photoelectric conversion module 200 performing the electro-optical conversion on the second electrical signal to obtain the first measuring optical signal, see Figure 2 The corresponding description is not repeated in detail. Then, the photoelectric conversion module sends the first measurement light signal to the first measuring instrument.

[0122] Step 404: The first measuring instrument sends a first sending performance indicator to the first measuring device.

[0123] In this embodiment, the first measuring instrument obtains the first transmission performance indicator according to the first measurement optical signal from the photoelectric conversion module. For the description of the first measuring instrument in this embodiment, please refer to Figure 1 The corresponding description is not repeated in detail. This embodiment takes the first transmission performance indicator as TDECQ as an example, without limitation, for example, the first transmission performance indicator can also be extinction ratio (ER) or optical modulation amplitude (OMA), etc., as long as the first transmission performance indicator can reflect the quality of the TX channel of the optoelectronic conversion module.

[0124] Optionally, after receiving the first sending performance indicator, the first measuring device may create a first sending side indicator list as shown in Table 2.

[0125] Table 2

[0126]

[0127]

[0128] The first transmission side indicator list shown in Table 2 creates a correspondence between the transmission link parameter and the transmission performance indicator. If the first transmission link parameter shown above is transmission link parameter 1, then the transmission performance indicator received by the first measuring device from the first measuring instrument is transmission performance indicator 1, and the first measuring device can store the correspondence between transmission link parameter 1 and transmission performance indicator 1 in the first transmission side indicator list shown in Table 2.

[0129] Step 405 : The first measuring device determines whether the first transmission performance indicator is within the transmission performance indicator range. If not, execute step 406 ; if yes, execute step 407 .

[0130] The first measuring device shown in this embodiment pre-configures the transmission performance indicator range. Taking the first transmission performance indicator as TDECQ as an example, the first measuring instrument can send the first transmission performance indicator to the first measuring device. For another example, the first measuring device can be configured with an operation interface, such as a touch screen, keyboard, mouse or voice control interface, etc., to receive instructions input by another device or manually, and the instructions are used to carry the first transmission performance indicator. In the case that TDECQ is within the range of the transmission performance indicator, it means that under the first transmission link parameters, the TX channel of the optoelectronic conversion module meets the quality standards. If TDECQ is not within the range of the transmission performance indicator, it means that under the first transmission link parameters, the quality of the TX channel of the optoelectronic conversion module does not meet the quality standards.

[0131] Step 406: The first measuring device determines that the TX channel of the photoelectric conversion module does not meet the quality standard.

[0132] Step 407 : The first measuring device determines whether the TX channel traversal condition is met, and if so, executes step 408 ; if not, executes step 409 .

[0133] The TX channel traversal condition shown in this embodiment means that the first measurement device has obtained the transmission performance indicator corresponding to each of the M transmission link parameters. In this embodiment, for the description of the process of the first measurement device obtaining the transmission performance indicator corresponding to each transmission link parameter, please refer to the description of the first measurement device obtaining the first transmission performance indicator corresponding to the first transmission link parameter shown in the above steps, and the details are not repeated here. Optionally, in the case where the TX configuration list shown in Table 1 includes M transmission link parameters, each time the first measurement device obtains a transmission performance indicator corresponding to a transmission link parameter, it is stored in the first transmission side indicator list shown in Table 2. The first measurement device compares Table 1 and Table 2 to determine whether the first measurement device has obtained the transmission performance indicator corresponding to each of the M transmission link parameters, and then determines whether the TX channel traversal condition is met.

[0134] Step 408: The first measuring device determines whether the TX channel of the photoelectric conversion module meets the quality standard.

[0135] In this embodiment, when the first measuring device determines that the transmission performance index corresponding to each of the M transmission link parameters is within the transmission performance index range, the first measuring device determines that the TX channel of the photoelectric conversion module meets the quality standard. It can be understood that through step 408, the first measuring device determines that the TX channel of the photoelectric conversion module meets the quality standard.

[0136] Step 409: The first measuring device attenuates the third electrical signal according to the second transmission link parameter to obtain a fourth electrical signal.

[0137] Specifically, the first measuring device generates a third electrical signal. For the description of the first measuring device generating the third electrical signal, please refer to the description of the first measuring device generating the first electrical signal shown in step 401, and no further details are given. In the TX configuration list shown in Table 1 pre-stored by the first measuring device shown in this embodiment, the second transmission link parameters are different from the first transmission link parameters, and the first measuring device does not obtain the transmission performance indicators corresponding to the second transmission link parameters. For the description of the execution process of step 409 shown in this embodiment, please refer to step 401, and no further details are given.

[0138] Step 410: The first measuring device sends a fourth electrical signal to the photoelectric conversion module.

[0139] Step 411: The photoelectric conversion module sends a second measuring light signal to the first measuring instrument.

[0140] Specifically, the photoelectric conversion module electro-optically converts the fourth electrical signal from the first measuring device into a second measuring light signal, and sends the second measuring light signal to the first measuring instrument.

[0141] Step 412: The first measuring instrument sends a second sending performance indicator to the first measuring device.

[0142] In this embodiment, the first measuring instrument obtains the second transmission performance indicator according to the second measurement optical signal. For the specific obtaining process, please refer to the description of the first measuring instrument obtaining the first transmission performance indicator shown above, and the details are not repeated here.

[0143] Step 413 : The first measuring device determines whether the second transmission performance indicator is within the transmission performance indicator range; if not, the process returns to step 406 ; if so, the process returns to step 407 .

[0144] For instructions on the first measuring device determining whether the second sending performance indicator is within the sending performance indicator range, please refer to the instructions on the first measuring device determining whether the first sending performance indicator is within the sending performance indicator range shown in step 405, and the details are not repeated here.

[0145] If the first measurement device determines the third transmission link parameter in step 407, and among the M transmission link parameters, the third transmission link parameter is different from the first transmission link parameter and the second transmission link parameter, then the process for the first measurement device to obtain the corresponding third transmission performance indicator according to the third transmission link parameter can be referred to as the process for the first measurement device to obtain the corresponding second transmission performance indicator according to the second transmission link parameter shown above, and the details will not be repeated here.

[0146] By adopting the method shown in this embodiment, the first measuring device simulates one or more effects such as insertion loss, crosstalk or reflection caused by the TX channel of the device on the electrical signal by attenuating the amplitude of the electrical signal to be sent to the optoelectronic conversion module. In addition, the first measuring device can attenuate the electrical signal to be sent to the optoelectronic conversion module according to different transmission link parameters, so that the first measuring device can simulate various possible link conditions of the TX channel of the device, and then measure the quality of the optoelectronic conversion module under different link conditions of the TX channel of the device, thereby improving the accuracy of the quality measurement of the optoelectronic conversion module.

[0147] Figure 5 The second embodiment of the measurement method provided in this application is a flowchart of the execution steps. In the measurement method shown in this embodiment, the first measurement device can also simulate the TX channel of the device and the TX channel of the photoelectric conversion module for various compensations of the electrical signal. For a description of the measurement system used in the method shown in this embodiment, please refer to Figure 3 The corresponding instructions are not elaborated in detail.

[0148] Step 501: A measuring device compensates a first electrical signal to be measured according to a first sending compensation parameter to obtain a first electrical signal.

[0149] First, the first measuring device generates a first electrical signal to be measured. Specifically, the first measuring device generates the first electrical signal to be measured according to pre-configured parameters, and the pre-configured parameters may be parameters such as service rate, modulation format, and measurement pattern, which are not specifically limited. Secondly, the first measuring device compensates the first electrical signal to be measured according to the first transmission compensation parameter to obtain the first electrical signal.

[0150] Specifically, in order to reduce the power consumption of the photoelectric conversion module, the device can compensate the electrical signal to be sent to the photoelectric conversion module to suppress ISI, improve the quality of the optical signal output by the photoelectric conversion module according to the electrical signal, and reduce the bit error rate. The first measuring device shown in this embodiment can simulate the compensation of the electrical signal to be sent to the photoelectric conversion module by the device. Specifically, the first measuring device pre-configures the list of sending compensation parameters shown in Table 3:

[0151] Table 3

[0152] Send compensation parameter 1 Send compensation parameter 2 Send compensation parameter 3 …… Send compensation parameter J

[0153] As shown in Table 3, the list of transmission compensation parameters stored in the first measuring device includes J transmission compensation parameters, namely, transmission compensation parameter 1, transmission compensation parameter 2 to transmission compensation parameter J, and J shown in this embodiment is an arbitrary integer greater than or equal to 1. The first measuring device simulates the compensation of the device for different degrees of insertion loss of the electrical signal to be sent to the optoelectronic conversion module through the transmission compensation parameters with different values ​​shown in Table 3. The compensation range of the J compensation parameters is consistent with the compensation range of the service chip TX interface in actual use.

[0154] The first transmission compensation parameter is one of the J transmission compensation parameters shown in Table 2. For example, if the first transmission compensation parameter is XdB, the first measurement device will simulate the device to compensate the insertion loss of XdB for the electrical signal to be sent to the optoelectronic conversion module to suppress ISI.

[0155] Step 502: The first measuring device attenuates the amplitude of the first electrical signal according to the first transmission link parameter to obtain a second electrical signal.

[0156] For a description of the execution process of step 502 shown in this embodiment, please refer to Figure 4 The corresponding step is shown in step 401 and will not be described in detail.

[0157] Step 503: The first measuring device sends a second electrical signal to the photoelectric conversion module.

[0158] In the case where the first measuring device attenuates the amplitude of the first electrical signal according to the first transmission link parameter to obtain the second electrical signal, the first measuring device sends the second electrical signal to the optoelectronic conversion module.

[0159] Step 504: The photoelectric conversion module sends a first measuring light signal to the first measuring instrument.

[0160] The photoelectric conversion module performs an electro-optical conversion on the second target electrical signal from the first measuring device to obtain a first measuring optical signal, and sends the first measuring optical signal to the first measuring instrument.

[0161] Step 505: The first measuring instrument sends a first sending performance indicator to the first measuring device.

[0162] The photoelectric conversion module sends a first measurement optical signal to the first measuring instrument, and the first measuring instrument obtains a first transmission performance indicator according to the first measurement optical signal.

[0163] For the execution process of step 503 to step 505 shown in this embodiment, please refer to Figure 4 The corresponding steps 402 to 404 are shown and will not be described in detail.

[0164] Step 506 : The first measuring device determines whether the first transmission performance indicator is within the transmission performance indicator range. If not, execute step 509 .

[0165] First, the first measuring device receives a first transmission performance indicator from a first measuring instrument.

[0166] Optionally, after receiving the first sending performance indicator, the first measuring device may create three different sending side indicator lists:

[0167] For example, as shown in Table 4, the second sending side indicator list shown in Table 4 creates a correspondence between M sending link parameters corresponding to each sending compensation parameter in J sending compensation parameters and M sending performance indicators.

[0168] Table 4

[0169]

[0170] The second transmission side indicator list as shown in Table 4 creates a correspondence between each transmission compensation parameter, each transmission link parameter, and the transmission performance indicator. If the first transmission compensation parameter used to perform step 501 as shown above is the transmission compensation parameter J, and the first transmission link parameter is the transmission link parameter 1, then the transmission performance indicator received by the first measuring device from the first measuring instrument is the transmission performance indicator 1, and the first measuring device can store the correspondence between the transmission compensation parameter J, the transmission link parameter 1, and the transmission performance indicator 1 in the second transmission side indicator list shown in Table 4.

[0171] For another example, as shown in the third transmission side indicator list in Table 5, the third transmission side indicator list shown in Table 5 creates a correspondence between M transmission link parameters and M transmission performance indicators corresponding to each transmission channel compensation parameter among K transmission channel compensation parameters.

[0172] Table 5

[0173]

[0174] In order to reduce power consumption and suppress ISI, the photoelectric conversion module can compensate the electrical signal from the first measuring device according to one of the K transmission channel compensation parameters, thereby improving the quality of the optical signal output by the photoelectric conversion module and reducing the bit error rate. The first measuring device pre-stores the K transmission channel compensation parameters used by the photoelectric conversion module to compensate for the electrical signal, and K shown in this embodiment is an arbitrary integer greater than or equal to 1. The photoelectric conversion module compensates the electrical signal from the first measuring device according to the transmission channel compensation parameters with different values ​​shown in Table 5 to compensate for the different degrees of insertion loss of the electrical signal. For the description of the values ​​of the K transmission channel compensation parameters, refer to the description of the J transmission compensation parameters, and the details are not repeated here.

[0175] If the first measuring device determines that the optoelectronic conversion module currently compensates for the electrical signal based on the first transmitting channel compensation parameter (for example, the transmitting channel compensation parameter K), the first measuring device determines that the first transmitting link parameter is the transmitting link parameter 1, and the first transmitting performance indicator received from the first measuring instrument is the transmitting performance indicator 1, then the first measuring device stores the correspondence between the transmitting channel compensation parameter K, the transmitting link parameter 1 and the transmitting performance indicator 1 in the third transmitting side indicator list as shown in Table 5.

[0176] For another example, as shown in Table 6, the fourth sending side indicator list shown in Table 6 creates a correspondence between J sending compensation parameters corresponding to each sending channel compensation parameter among the K sending channel compensation parameters, and M sending link parameters and M sending performance indicators corresponding to each compensation parameter among the J sending compensation parameters.

[0177] Table 6

[0178]

[0179] In the fourth sending side indicator list shown in Table 6, for the description of the K sending channel compensation parameters, please refer to the corresponding description of Table 5, and for the description of the J sending compensation parameters, please refer to the corresponding description of Table 4, and the details are not repeated here.

[0180] If the first measuring device determines that the optoelectronic conversion module currently compensates for the electrical signal based on the first transmitting channel compensation parameter (for example, the transmitting channel compensation parameter K), and the first measuring device compensates the electrical signal to be sent to the optoelectronic conversion module based on the transmitting compensation parameter J, and the first transmitting link parameter is the transmitting link parameter 1, then the transmitting performance indicator received by the first measuring device from the first measuring instrument is the transmitting performance indicator 1, and the first measuring device can store the correspondence between the transmitting channel compensation parameter K, the transmitting compensation parameter J, the transmitting link parameter 1 and the transmitting performance indicator 1 in the fourth transmitting side indicator list shown in Table 6.

[0181] The first measurement device shown in this embodiment pre-configures the transmission performance indicator range. Taking TDECQ as the first transmission performance indicator, when TDECQ is within the transmission performance indicator range, it means that under the first transmission link parameters, the TX channel of the optoelectronic conversion module meets the quality standards.

[0182] If the first measuring device determines that the first transmission performance indicator is within the transmission performance indicator range, the execution process is described in Figure 4 The description of the execution process of the corresponding steps 407 to 413 is not repeated in detail.

[0183] Step 507 : The first measuring device determines whether the TX channel traversal condition is met. If so, execute step 508 ; if not, execute step 517 .

[0184] For a description of the execution process of step 507 shown in this embodiment, please refer to Figure 4 The corresponding step is shown in step 407 and will not be described in detail.

[0185] Step 508: The first measuring device determines whether the TX channel of the photoelectric conversion module meets the quality standard.

[0186] In this embodiment, when the first measuring device determines that the transmission performance index corresponding to each of the M transmission link parameters is within the transmission performance index range, the first measuring device determines that the TX channel of the photoelectric conversion module meets the quality standard. It can be understood that through step 508, the first measuring device determines that the TX channel of the photoelectric conversion module meets the quality standard.

[0187] Step 509 , the first measuring device determines whether the compensation traversal condition is satisfied, if so, executes step 510 , if not, executes step 511 .

[0188] In this embodiment, the compensation traversal conditions are different as the sending side indicator list stored in the first measuring device is different.

[0189] For example, if the first measurement device stores the second transmission side indicator list as shown in Table 4, satisfying the compensation traversal condition means that the first measurement device obtains M transmission link parameters and M transmission performance indicators corresponding to each transmission compensation parameter among the J transmission compensation parameters. For another example, if the first measurement device stores the third transmission side indicator list as shown in Table 5, satisfying the compensation traversal condition means that the first measurement device obtains M transmission link parameters and M transmission performance indicators corresponding to each transmission channel compensation parameter among the K transmission channel compensation parameters. For another example, if the first measurement device stores the fourth transmission side indicator list as shown in Table 6, satisfying the compensation traversal condition means that the first measurement device obtains J transmission compensation parameters corresponding to each transmission channel compensation parameter among the K transmission channel compensation parameters, and M transmission link parameters and M transmission performance indicators corresponding to each transmission compensation parameter among the J transmission compensation parameters. This embodiment takes the example that the first measurement device creates the fourth transmission side indicator list as shown in Table 6.

[0190] Step 510: The first measuring device determines that the TX channel of the photoelectric conversion module does not meet the quality standard.

[0191] It can be understood that if the first transmission performance indicator is not within the transmission performance indicator range, and the first measuring device determines that the compensation traversal condition has been met, then the first measuring device determines that the TX channel of the optoelectronic conversion module does not meet the quality standard.

[0192] Step 511: The first measuring device obtains a second transmission compensation parameter and a second transmission channel compensation parameter.

[0193] The second transmission compensation parameter shown in this embodiment is different from the first transmission compensation parameter, the second transmission channel compensation parameter is different from the first transmission channel compensation parameter, and the first measuring device does not obtain the transmission performance indicator corresponding to the second transmission compensation parameter and the second transmission channel compensation parameter. In the case where the first measuring device shown in this embodiment obtains the second transmission compensation parameter and the second transmission channel compensation parameter, the first measuring device updates the first transmission compensation parameter to the second transmission compensation parameter, then the first measuring device compensates the electrical signal to be sent to the photoelectric conversion module according to the second transmission compensation parameter. The first measuring device also sends the second transmission channel compensation parameter to the photoelectric conversion module, then the photoelectric conversion module updates the first transmission channel compensation parameter to the second transmission channel compensation parameter, and the photoelectric conversion module compensates the electrical signal from the first measuring device according to the second transmission channel compensation parameter.

[0194] Step 512: The first measuring device compensates the second electrical signal to be measured according to the second sending compensation parameter to obtain a fifth electrical signal.

[0195] First, the first measuring device generates a second electrical signal to be measured. In this embodiment, the first measuring device generates the second electrical signal to be measured according to pre-configured parameters, and the pre-configured parameters may be parameters such as service rate, modulation format, and measurement pattern, which are not specifically limited. Secondly, the first measuring device compensates the second electrical signal to be measured according to the second transmission compensation parameter to obtain a fifth electrical signal. For the description of the first measuring device shown in this embodiment obtaining the fifth electrical signal, please refer to the description of the process of the measuring device obtaining the first electrical signal shown in step 501, and no further details will be given.

[0196] Step 513: The first measuring device attenuates the fifth electrical signal according to the first transmission link parameter to obtain a sixth electrical signal.

[0197] Step 514: The first measuring device sends a sixth electrical signal to the photoelectric conversion module.

[0198] Step 515: The photoelectric conversion module sends a third measuring light signal to the first measuring instrument.

[0199] Step 516: The first measuring instrument sends the third sending performance indicator to the first measuring device.

[0200] Step 517 : The first measuring device determines whether the third transmission performance indicator is within the transmission performance indicator range; if not, the process returns to step 509 ; if so, the process returns to step 507 .

[0201] For the description of the execution process of steps 511 to 516 shown in this embodiment, please refer to steps 501 to 506, and the details are not repeated here.

[0202] Using the method shown in this embodiment, the first measuring device compensates the electrical signal to be sent to the optoelectronic conversion module according to the sending compensation parameter, thereby simulating the compensation of the electrical signal by the TX channel of the device. The first measuring device also simulates one or more effects such as insertion loss, crosstalk or reflection on the electrical signal caused by the TX channel of the device according to the way of attenuating the amplitude of the electrical signal to be sent to the optoelectronic conversion module. Moreover, the first measuring device can attenuate the electrical signal to be sent to the optoelectronic conversion module according to different sending link parameters, so that the first measuring device can simulate various possible link conditions of the TX channel of the device, and then measure the quality of the optoelectronic conversion module under different link conditions of the TX channel of the device, thereby improving the accuracy of the quality measurement of the optoelectronic conversion module.

[0203] Figure 6A flowchart of the execution steps of the third embodiment of the measurement method provided in this application. In the measurement method shown in this embodiment, the transmission performance index obtained by the first measurement device can reflect the different conditions of the TX channel of the photoelectric conversion module, so that the measured performance index can accurately reflect the quality of the photoelectric conversion module and obtain the corresponding transmission configuration information. For a description of the measurement system used by the method shown in this embodiment, please refer to Figure 3 The corresponding instructions are not elaborated in detail.

[0204] Step 601: A first measuring device attenuates a first electrical signal according to a first transmission link parameter to obtain a second electrical signal.

[0205] Step 602: The first measuring device sends a second electrical signal to the photoelectric conversion module.

[0206] Step 603: The photoelectric conversion module sends a first measuring light signal to the first measuring instrument.

[0207] Step 604: The first measuring instrument sends a first sending performance indicator to the first measuring device.

[0208] For a description of the execution process of steps 601 to 604 shown in this embodiment, please refer to Figure 4 The corresponding steps 401 to 404 are shown, and the specific execution process is not repeated here.

[0209] The first measuring device may pre-store three different sending traversal lists.

[0210] For example, as shown in the first sending traversal list in Table 7, the first sending traversal list in Table 7 is used to create a corresponding relationship between the sending performance indicators corresponding to each sending compensation parameter in J sending compensation parameters.

[0211] Table 7

[0212] Send compensation parameters Sending performance indicators Send compensation parameter 1 Send performance indicator 1 Send compensation parameter 2 Send performance indicator 2 …… …… Send compensation parameter J Send performance index J

[0213] For a description of the J send compensation parameters, see Figure 5 If the first transmission compensation parameter shown above is the transmission compensation parameter J, then the first transmission performance indicator received by the first measuring device from the first measuring instrument is the transmission performance indicator J, and the first measuring device can store the corresponding relationship between the transmission compensation parameter J and the transmission performance indicator J in the first transmission traversal list shown in Table 7.

[0214] For another example, as shown in the second sending traversal list in Table 8, the second sending traversal list in Table 8 creates a corresponding relationship between the sending performance indicators corresponding to each sending channel compensation parameter among the K sending channel compensation parameters.

[0215] Table 8

[0216] Send channel compensation parameters Sending performance indicators Send channel compensation parameter 1 Send performance indicator 1 Send channel compensation parameter 2 Send performance indicator 2 …… …… Send channel compensation parameter K Send performance index K

[0217] For a description of the compensation parameters for the K transmission channels, see Figure 5 The corresponding instructions are not described in detail. The above-mentioned photoelectric conversion module compensates the electrical signal from the first measuring device according to the first transmission channel compensation parameter (for example, the first transmission channel compensation parameter is the transmission channel compensation parameter K). Then, the first transmission performance indicator received by the first measuring device from the first measuring instrument is the transmission performance indicator K, and the first measuring device can store the corresponding relationship between the transmission channel compensation parameter K and the transmission performance indicator K in the second transmission traversal list shown in Table 8.

[0218] For another example, as shown in the third sending traversal list in Table 9, the third sending traversal list in Table 9 creates a correspondence between J sending compensation parameters corresponding to each sending channel compensation parameter and J sending performance indicators among the K sending channel compensation parameters.

[0219] Table 9

[0220]

[0221] If the first sending compensation parameter shown above is the sending compensation parameter J, and the photoelectric conversion module compensates the electrical signal from the first measuring device according to the first sending channel compensation parameter (for example, the first sending channel compensation parameter is the sending channel compensation parameter K), then the first sending performance indicator received by the first measuring device from the first measuring instrument is the sending performance indicator J, and the first measuring device can store the correspondence between the sending channel compensation parameter K, the sending compensation parameter J and the sending performance indicator J in the third sending traversal list shown in Table 9.

[0222] Step 605 : The first measuring device determines whether the compensation traversal condition is met. If so, execute step 606 .

[0223] In this embodiment, the compensation traversal conditions are different as the sending traversal list stored in the first measuring device is different.

[0224] For example, if the first measurement device stores a first transmission traversal list as shown in Table 7, satisfying the compensation traversal condition means that the first measurement device has obtained the transmission performance indicator corresponding to each transmission compensation parameter among the J transmission compensation parameters. For another example, if the first measurement device stores a second transmission traversal list as shown in Table 8, satisfying the compensation traversal condition means that the first measurement device has obtained the transmission performance indicator corresponding to each transmission channel compensation parameter among the K transmission channel compensation parameters. For another example, if the first measurement device stores a third transmission traversal list as shown in Table 9, satisfying the compensation traversal condition means that the first measurement device has obtained J transmission compensation parameters and J transmission performance indicators corresponding to each transmission channel compensation parameter among the K transmission channel compensation parameters. This embodiment takes the example that the first measurement device has created the third transmission traversal list as shown in Table 9.

[0225] Step 606: The first measuring device obtains a target sending performance indicator.

[0226] The transmission performance indicator shown in this embodiment is the TDECQ indicator. Then, if the first measurement device has stored the first transmission traversal list shown in Table 7, the target transmission performance indicator is the minimum value of all transmission performance indicators stored in the first transmission traversal list. If the first measurement device has stored the second transmission traversal list shown in Table 8, the target transmission performance indicator is the minimum value of all transmission performance indicators stored in the second transmission traversal list. If the first measurement device has stored the third transmission traversal list shown in Table 9, the target transmission performance indicator is the minimum value of all transmission performance indicators stored in the third transmission traversal list.

[0227] It should be clear that the present embodiment does not limit the type of transmission performance indicator, as long as the transmission performance indicator can reflect the quality of the TX channel of the optoelectronic conversion module. For example, the transmission performance indicator may also be an extinction ratio or an optical modulation amplitude. Then, if the first measuring device has stored the first transmission traversal list as shown in Table 7, the target transmission performance indicator is the maximum value of all transmission performance indicators stored in the first transmission traversal list. If the first measuring device has stored the second transmission traversal list as shown in Table 8, the target transmission performance indicator is the maximum value of all transmission performance indicators stored in the second transmission traversal list. If the first measuring device has stored the third transmission traversal list as shown in Table 9, the target transmission performance indicator is the maximum value of all transmission performance indicators stored in the third transmission traversal list.

[0228] Step 607 : The first measuring device determines whether the target transmission performance indicator is within the transmission performance indicator range. If not, execute step 608 ; if yes, execute step 609 .

[0229] Step 608: The first measuring device determines that the TX channel of the photoelectric conversion module does not meet the quality standard.

[0230] Step 609 : The first measuring device determines whether the TX channel traversal condition is met. If so, step 610 is executed; if not, step 612 is executed.

[0231] Step 610: The first measuring device determines whether the TX channel of the photoelectric conversion module meets the quality standard.

[0232] Step 611: The first measurement device obtains sending configuration information.

[0233] The transmission configuration information shown in this embodiment includes the correspondence between the target transmission link parameter, the target transmission performance index, the target transmission compensation parameter and the target transmission channel compensation parameter. The transmission configuration information can be shown in Table 10:

[0234] Table 10

[0235] Target send link parameters Target sending performance index Target sends compensation parameters Target send channel compensation parameters Send link parameter M Target transmission performance index J Send compensation parameter J Send channel compensation parameter 1

[0236] Taking the traversal list stored in the first measuring device shown in this embodiment as the third transmission traversal list shown in Table 10 as an example, the first measuring device determines the target transmission performance indicator as the target transmission performance indicator J through step 607, and determines the target transmission channel compensation parameter used to obtain the target transmission performance indicator J as the transmission channel compensation parameter 1, and also determines the target transmission compensation parameter used to obtain the target transmission performance indicator J as the transmission compensation parameter J, and the target transmission link parameter used to obtain the target transmission performance indicator J as the first transmission link parameter. In this embodiment, the first transmission link parameter is the transmission link parameter M as an example. It can be understood that the first measuring device compensates the first electrical signal to be measured based on the transmission compensation parameter J (see step 601 for details), attenuates the electrical signal based on the transmission link parameter M (see step 604 for details), and the photoelectric conversion module compensates the electrical signal from the first measuring device based on the transmission channel compensation parameter 1 (see step 605 for details), which enables the first measuring device to obtain the target transmission performance indicator J.

[0237] In this embodiment, the transmission configuration information includes the target transmission compensation parameter and the target transmission channel compensation parameter as an example. In other examples, the transmission configuration information includes the corresponding relationship between the target transmission link parameter and the target transmission performance index. For another example, the transmission configuration information includes the corresponding relationship between the target transmission link parameter, the target transmission performance index, and the target transmission compensation parameter. For another example, the transmission configuration information includes the corresponding relationship between the target transmission link parameter, the target transmission performance index, and the target transmission channel compensation parameter.

[0238] Step 612: The first measuring device attenuates the third electrical signal according to the second transmission link parameter to obtain a fourth electrical signal.

[0239] Among the M transmission link parameters pre-stored by the first measurement device shown in this embodiment, the second transmission link parameter is different from the first transmission link parameter, and the first measurement device does not obtain the transmission performance indicator corresponding to the second transmission link parameter.

[0240] Step 613: The first measuring device sends a fourth electrical signal to the photoelectric conversion module.

[0241] Step 614: The photoelectric conversion module sends a second measuring light signal to the first measuring instrument.

[0242] Step 615: The first measuring instrument sends the second sending performance indicator to the first measuring device, and returns to execute step 605.

[0243] For a description of the execution process of steps 612 to 615 shown in this embodiment, please refer to Figure 6 The corresponding steps 601 to 604 are shown and will not be described in detail.

[0244] Figures 4 to 6 In the embodiment shown, the quality of the TX channel of the photoelectric conversion module is measured as an example. If the photoelectric conversion module includes multiple TX channels, for the description of the multiple TX channels, please refer to Figure 2 If the photoelectric conversion module includes multiple TX channels, then the above steps are executed for each TX channel of the photoelectric conversion module. Figures 4 to 6 The method shown in any embodiment is used to obtain the quality of each TX channel. For example, the photoelectric conversion module is a single-fiber bidirectional module or a wavelength division multiplexing transceiver module. Then, a wavelength splitter is connected between the photoelectric conversion module and the first measuring instrument. The WDM included in the photoelectric conversion module is used to send the multiplexed optical signal to the wavelength splitter. The WDM splits the multiplexed optical signal into a measurement optical signal from the TX channel to be measured, and sends the measurement optical signal to the first measuring instrument. It can be understood that the wavelength splitter is used to ensure that each TX channel in the photoelectric conversion module can be separately executed as follows. Figures 4 to 6 The measurement process shown in any embodiment.

[0252] The measurement method provided in the embodiment of the present application can also measure the quality of the RX channel of the photoelectric conversion module. For the description of the RX channel of the photoelectric conversion module, please refer to Figure 2 In order to better understand the measurement method for measuring the quality of the RX channel of the photoelectric conversion module provided in the embodiment of the present application, first combine Fig.10 The structure of the existing measurement system for measuring the TX channel quality of the photoelectric conversion module is described as shown, wherein: Fig.10 This is another structural example diagram of an existing measurement system.

[0253] The existing measurement system includes a measuring instrument 1020, which is used to connect to the optical module to be measured 1010. Specifically, the measuring instrument 1020 includes a bit error rate tester (BERT) 1001, a reference optical transmitter 1002, an adjustable attenuator 1003, an optical splitter 1004 and an optical power meter 1005 connected in sequence, wherein the optical splitter 1004 is also connected to the optical module to be measured 1010.

[0254] The specific process of the existing measurement method is as follows: during the measurement of the RX channel of the optical module 1010 to be measured, the service rate, modulation format, amplitude or measurement pattern of the first measurement electrical signal of the bit error meter 1001 are set according to the optical module 1010 to be measured, and the measurement electrical signal is sent to the reference transmitter 1002, and the reference transmitter 1002 converts the measurement electrical signal into a measurement optical signal and sends it to the adjustable attenuator 1003. The attenuation value of the adjustable attenuator 1003 is adjusted to obtain an attenuated optical signal, and the attenuated optical signal is sent to the optical splitter 1004. The optical splitter 1004 splits the attenuated optical signal to obtain a first optical signal and a second optical signal, and sends the first optical signal to the optical power meter 1005, the optical power meter 1005 obtains the optical power value corresponding to the first optical signal, and the optical splitter 1004 sends the second optical signal to the optical module 1010 to be measured. The optical module 1010 to be tested performs photoelectric conversion on the second optical signal to obtain a measurement electrical signal, and the optical module 1010 to be tested sends the measurement electrical signal to the bit error meter 1001 to obtain the corresponding bit error rate. In the existing measurement method, the adjustable attenuator 1003 gradually adjusts the attenuation value until the bit error rate obtained by the bit error meter 1001 is within the specified range. When the bit error meter 1001 reads the bit error rate within the specified range, the target optical power value of the optical power meter 1005 is read, and the target optical power value is determined as the "receiver sensitivity". The extinction ratio is calculated based on the bit error rate within the specified range and the target optical power value. The "receiver optical modulation amplitude sensitivity" is then calculated based on the extinction ratio, and the "receiver optical modulation amplitude sensitivity" can reflect the quality of the RX channel of the optical module to be tested.

[0255] However, in the process of obtaining the "receiver optical modulation amplitude sensitivity", the existing measurement system cannot reflect the impact of different conditions of the optical module link on the "receiver optical modulation amplitude sensitivity", so that the measured "receiver optical modulation amplitude sensitivity" cannot accurately reflect the quality of the optical module.

For the description of the structure of the second measurement instrument 1100 shown in this embodiment, please refer to Fig.10 The second measuring device 1120 and the second measuring instrument 1100 are connected to the RX channel of the photoelectric conversion module 1110 to be measured. For the description of the RX channel structure of the photoelectric conversion module 1110, please refer to Figure 2The corresponding description is not repeated in detail. Optionally, the second measuring device 1120 shown in this embodiment also includes a communication channel for communicating with the photoelectric conversion module 1110, and the second measuring device 1120 configures the working parameters of the photoelectric conversion module 1100 through the communication channel. For example, the communication channel is connected to the communication bus of the photoelectric conversion module 1110. Optionally, the second measuring device 1120 also includes a feedback channel connected to the second measuring instrument 1110, and the second measuring device 1120 exchanges information with the second measuring instrument 1110 through the feedback channel. The second measuring instrument 1100 can be automatically adjusted based on the receiving performance index from the second measuring device 1120, thereby increasing the degree of automation of the execution process of the measurement method provided in the embodiment of the present application, reducing manual intervention, and improving measurement efficiency.

[0257] based on Fig.11 The measurement system shown, combined with Fig.12 The execution process of the measurement method provided in this embodiment is described as shown in FIG. Fig.12 This is a flowchart of the execution steps of the fourth embodiment of the measurement method provided by the present application. The measurement method shown in this embodiment is used to measure the quality of the RX channel of the photoelectric conversion module.

[0258] Step 1201: The second measuring instrument sends a first measuring optical signal to the photoelectric conversion module.

[0259] Specifically, the second measuring instrument generates a first electrical signal to be measured. Fig.11 As shown, the code generation unit 1101 of the second measuring instrument 1100 generates the first electrical signal to be measured according to pre-configured parameters. The pre-configured parameters may be service rate, modulation format, measurement pattern and other parameters, which are not specifically limited.

[0260] The reference optical transmitter of the second measuring instrument performs an electrical-to-optical conversion on the first electrical signal to be measured to obtain a measuring optical signal, and sends the measuring optical signal to the adjustable attenuator 1103. The adjustable attenuator 1103 attenuates the amplitude of the measuring optical signal to obtain a first attenuated optical signal. The adjustable attenuator sends the first attenuated optical signal to the optical splitter 1104. The optical splitter 1104 is used to split the first attenuated optical signal to obtain a first measuring optical signal and a third measuring optical signal. This embodiment does not limit the splitting ratio of the optical splitter 1104. For example, the splitting ratio of the optical splitter can be 50%:50%. Then, the optical splitter 1104 uses 50% of the first attenuated optical signal as the first measuring optical signal and sends it to the optoelectronic conversion module 1110, and uses 50% of the first attenuated optical signal as the third measuring optical signal and sends it to the optical power meter 1105.

[0261] Step 1202: The photoelectric conversion module sends a first measurement electrical signal to a second measurement device.

[0262] Specifically, the photoelectric conversion module photoelectrically converts the first measurement optical signal into a first measurement electrical signal, and the photoelectric conversion module sends the first measurement electrical signal to the second measurement device.

[0263] Step 1203: The second measurement device attenuates the first measurement electrical signal according to the first receiving link parameter to obtain a second measurement electrical signal.

[0264] The second measurement device pre-stores the RX configuration list shown in Table 11:

[0265] Table 11

[0266] Receive link parameters 1 Receive link parameters 2 Receive link parameters 3 …… Receive link parameter N

[0267] As shown in Table 11, the RX configuration list stored in the second measurement device includes N receiving link parameters, namely, receiving link parameter 1, receiving link parameter 2 to receiving link parameter N. N shown in this embodiment is any integer greater than or equal to 2.

[0268] When the photoelectric conversion module is used in a specific application, it needs to be connected to a device. For instructions on the device, see Figure 4 The corresponding description is not repeated in detail. When the photoelectric conversion module is connected to the device, the RX channel of the photoelectric conversion module is used to send the electrical signal after photoelectric conversion to the device. The RX channel of the photoelectric conversion module will bring one or more effects such as certain insertion loss, crosstalk or reflection to the electrical signal. The second measuring device shown in this embodiment is used to simulate the influence of the RX channel of the photoelectric conversion module on the electrical signal. The specific simulation method can be that the second measuring device attenuates the amplitude of the first measured electrical signal according to the first receiving link parameter to obtain the second measured electrical signal. The first receiving link parameter is one of the N receiving link parameters shown in Table 11. For example, the first receiving link parameter is XdB. If the RX channel of the photoelectric conversion module will increase the insertion loss of X dB to the electrical signal to be sent to the device, then, in order to realize the second measuring device simulating the insertion loss of the RX channel of the photoelectric conversion module to transmit the electrical signal, the second measuring device reduces the amplitude of the first measured electrical signal (i.e., reduces X dB) according to the first receiving link parameter. X is any value greater than 0. It can be understood that the second measuring device attenuates the amplitude of the first measurement electrical signal according to the first receiving link parameter, which is equivalent to the first electrical signal being transmitted through the RX channel of the photoelectric conversion module (the RX channel of the photoelectric conversion module increases the insertion loss of XdB on the first measurement electrical signal). It can be understood that the second measuring device simulates the different degrees of influence of the RX channel of the photoelectric conversion module on the electrical signal through the receiving link parameters with different values ​​shown in Table 11.

[0269] This embodiment does not limit the value range of the N receiving link parameters stored in the second measurement device. For example, the N receiving link parameters take values ​​within the range of 3 to 16 dB. The value range of N may be 1 to 14, and the step size of adjusting the receiving link parameter values ​​may be 1 dB. Then, when N=1, the sending link parameter 1=3dB, and when N=2, the sending link parameter 2=4dB, and so on. In specific applications, the step size of adjusting the receiving link parameter values ​​may be any value within the range of 1 to 25dB or 5 to 11dB, and this example does not limit the step size. The step size of adjusting the receiving link parameter values ​​may be greater than 1dB (for example, 3dB). For another example, the step size of adjusting the receiving link parameter values ​​may be less than 1dB (for example, 0.5dB). The above example takes different step sizes as the same value as an example. In other examples, different step sizes may also be different. For example, the N-1 step sizes used to obtain N receiving link parameters are 1dB, 1dB, 3dB, 3dB, 3dB, 1dB, 1dB, and so on. Then, the corresponding N receiving link parameters are 3dB, 4dB, 5dB, 8dB, 11dB, 14dB, 15dB, 16dB, and so on. This example can also be based on the most simplified example of receiving link parameters. For example, the value range of the N receiving link parameters shown in this example is between 1 and 25dB. Then, the second measurement device stores two receiving link parameters, and the two receiving link parameters are the maximum value (i.e., 25dB) and the minimum value (i.e., 1dB) between 1 and 25dB.

[0270] In this embodiment, the second measuring device simulates the insertion loss of the electric signal transmitted by the RX channel of the photoelectric conversion module according to the N receiving link parameters as an example. In other examples, the second measuring device may also simulate different link crosstalk values ​​of the RX channel of the photoelectric conversion module according to the N receiving link parameters, and then the value range of the N receiving link parameters may be between -50 and -35 dB. For another example, the second measuring device may also simulate different link reflection values ​​of the RX channel of the photoelectric conversion module according to the N receiving link parameters, and then the value range of the N receiving link parameters may be between -15 and -10 dB.

[0271] The N receiving link parameters may also be a combination of a series of insertion loss values, link crosstalk values ​​and link reflection values, such as an insertion loss value range of 1 to 25 dB, a link crosstalk value range of -50 to -35 dB, and a link reflection value range of -15 to -10 dB. One of the receiving link parameters may be: an insertion loss value of 1 dB, a link crosstalk value of -50 dB, and a link reflection value of -15 dB.

[0272] Step 1204: The second measuring device detects that the bit error rate of the second measurement electrical signal is within a preset bit error rate range.

[0273] The second measuring instrument shown in this embodiment includes an adjustable attenuator that gradually adjusts the attenuation value to gradually adjust the optical power of the received optical signal after the first attenuation until the second measuring device detects that the bit error rate corresponding to the optical signal after the first attenuation is within a preset bit error rate range.

[0274] Step 1205: The second measuring device obtains a first receiving performance indicator.

[0275] In this embodiment, the first receiving performance indicator is taken as the receiver optical modulation amplitude sensitivity (outer optical modulation amplitude, OMAouter) as an example. Specifically, when the bit error rate of the received optical signal after the first attenuation is within the preset bit error rate range, the optical power value on the optical power meter of the second measuring instrument is read, and the optical power value is recorded as the "receiver sensitivity". The extinction ratio of the optical transmitter of the second measuring instrument is obtained, and the extinction ratio is the ratio of the "receiver sensitivity" to the optical power of the first measured optical signal. The second measuring device calculates the first receiving performance indicator based on the "receiver sensitivity" and the extinction ratio of the optical transmitter of the second measuring instrument. In this embodiment, the second measuring device calculates the first receiving performance indicator based on the "receiver sensitivity" and the extinction ratio of the optical transmitter of the second measuring instrument as an example. In other examples, the first receiving performance indicator can be calculated manually or by any device, and the first receiving performance indicator can be sent to the second measuring device.

[0276] In the case where the first receiving performance indicator is OMAouter for example, the second measuring device may calculate OMAouter based on the following calculation formula;

[0277]

[0278] Among them, PIN AVg is the optical power value on the power meter shown above, that is, the “receiver sensitivity.” After the second measuring device obtains the first receiving performance indicator, a first receiving side indicator list as shown in Table 12 may be created.

[0279] Table 12

[0280] Receive link parameters Receiving performance indicators Receive link parameters 1 Receiving performance index 1 Receive link parameters 2 Receiving performance index 2 Receive link parameters 3 Receiving performance index 3 …… …… Receive link parameter N Receiving performance index N

[0281] The first receiving side indicator list shown in Table 12 creates a correspondence between each receiving link parameter and the receiving performance indicator. If the first receiving link parameter shown above is receiving link parameter 1, then the corresponding receiving performance indicator obtained by the second measurement device is receiving performance indicator 1, and the second measurement device can store the correspondence between receiving link parameter 1 and receiving performance indicator 1 in the first receiving side indicator list shown in Table 12.

[0282] Step 1206 , the second measuring device determines whether the first receiving performance indicator is within the receiving performance indicator range, if not, execute step 1207 , if yes, execute step 1209 .

[0283] The second measurement device shown in this embodiment pre-configures the reception performance index range. When the first reception performance index range is within the reception performance index range, it means that the RX channel of the photoelectric conversion module meets the quality standard under the first reception link parameters. If the first reception performance index is not within the reception performance index range, it means that the quality of the RX channel of the photoelectric conversion module does not meet the quality standard under the first reception link parameters.

[0284] Step 1207: The second measuring device determines that the RX channel of the photoelectric conversion module does not meet the quality standard.

[0285] Step 1208 : The second measuring device determines whether the RX channel traversal condition is met. If so, execute step 1209 ; if not, execute step 1212 .

[0286] Satisfying the RX channel traversal condition shown in this embodiment means that the receiving performance indicator corresponding to each receiving link parameter in the N receiving link parameters has been obtained. In this embodiment, for the description of the process of the second measuring device obtaining the receiving performance indicator corresponding to each receiving link parameter, please refer to the description of the second measuring device obtaining the first receiving performance indicator corresponding to the first receiving link parameter shown in the above steps, and the details are not repeated here. Optionally, in the case where the RX configuration list shown in Table 11 includes N receiving link parameters, each time the second measuring device obtains a receiving performance indicator corresponding to a receiving link parameter, it is stored in the first receiving side indicator list shown in Table 12. The second measuring device compares Table 11 and Table 12 to determine whether the second measuring device has obtained the receiving performance indicator corresponding to each receiving link parameter in the N receiving link parameters.

[0287] Step 1209: The second measuring device determines whether the RX channel of the photoelectric conversion module meets the quality standard.

[0288] In this embodiment, when the second measuring device determines that the receiving performance indicator corresponding to each receiving link parameter in the N receiving link parameters has been obtained, the second measuring device determines that the RX channel of the photoelectric conversion module meets the quality standard. It can be understood that through step 1209, the second measuring device determines that the RX channel of the photoelectric conversion module meets the quality standard.

[0289] Step 1210: The second measuring instrument sends a second measuring light signal to the photoelectric conversion module.

[0290] Specifically, the second measuring instrument generates a second electrical signal to be measured. The second measuring device shown in this embodiment can send a trigger signal to the second measuring instrument, and the trigger signal is used to trigger the second measuring instrument to generate a second electrical signal to be measured. For the description of the second electrical signal to be measured, please refer to the description of the first electrical signal to be measured shown in step 1201, and the specific details are not repeated. The reference optical transmitter of the second measuring instrument performs electro-optical conversion on the second electrical signal to be measured to obtain a measurement optical signal, and sends the measurement optical signal to the adjustable attenuator 1103. The adjustable attenuator 1103 attenuates the amplitude of the measurement optical signal to obtain a second attenuated received optical signal. The adjustable attenuator sends the second attenuated received optical signal to the optical splitter 1104. The optical splitter 1104 is used to split the second attenuated received optical signal to obtain a second measurement optical signal and a fourth measurement optical signal. The optical splitter 1104 sends the second measurement optical signal to the photoelectric conversion module 1110, and sends the fourth measurement optical signal to the optical power meter 1105.

[0291] Step 1211: The photoelectric conversion module sends a third measurement electrical signal to the second measurement device.

[0292] Specifically, the photoelectric conversion module photoelectrically converts the second measurement optical signal into a third measurement electrical signal, and the photoelectric conversion module sends the third measurement electrical signal to the second measurement device.

[0293] Step 1212: The second measuring device attenuates the third measurement electrical signal according to the second receiving link parameter to obtain a fourth measurement electrical signal.

[0294] The second receiving link parameters shown in this embodiment are different from the first receiving link parameters among the N receiving link parameters shown in Table 11.

[0295] Step 1213: The second measuring device detects that the bit error rate of the fourth measurement electrical signal is within a preset bit error rate range.

[0296] Step 1214: The second measuring device obtains a second receiving performance indicator.

[0297] Step 1215: The second measuring device determines whether the second receiving performance indicator is within the receiving performance indicator range. If not, the process returns to step 1207; if so, the process returns to step 1208.

[0298] For the description of the execution process of steps 1211 to 1215 shown in this embodiment, please refer to the description of the execution process of steps 1202 to 1206, and the details are not repeated here.

[0299] By adopting the method shown in this embodiment, the second measuring device simulates one or more effects such as insertion loss, crosstalk or reflection of the RX channel of the device on the electrical signal by attenuating the amplitude of the electrical signal from the optoelectronic conversion module. In addition, the second measuring device can attenuate the electrical signal from the optoelectronic conversion module according to different receiving link parameters, so that the second measuring device can simulate various possible link conditions of the RX channel of the device, and then measure the quality of the RX channel of the optoelectronic conversion module under different link conditions, thereby improving the accuracy of the quality measurement of the optoelectronic conversion module.

[0300] Fig.13 The fifth embodiment of the measurement method provided in this application is a flowchart of the execution steps. In the measurement method shown in this embodiment, the second measurement device can also simulate the various compensations of the RX channel of the device and the RX channel of the photoelectric conversion module for the electrical signal. For a description of the measurement system used in the method shown in this embodiment, please refer to Fig.11 The corresponding instructions are not elaborated in detail.

[0301] Step 1301: The second measuring instrument sends a first measuring light signal to the photoelectric conversion module.

[0302] Step 1302: The photoelectric conversion module sends a first measurement electrical signal to a second measurement device.

[0303] Step 1303: The second measurement device attenuates the first measurement electrical signal according to the first receiving link parameter to obtain a second measurement electrical signal.

[0304] For a description of the execution process of steps 1301 to 1303 shown in this embodiment, please refer to Fig.12 The corresponding description of the execution process of step 1201 to step 1203 is not repeated in detail.

[0305] Step 1304: The second measuring device compensates the second measurement electrical signal according to the first receiving compensation parameter to obtain a first indicator electrical signal.

[0306] The RX channel of the photoelectric conversion module can compensate for the electrical signal to be sent to the device to suppress ISI, improve the quality of the electrical signal output by the photoelectric conversion module, and reduce the bit error rate. The second measuring device shown in this embodiment can compensate the electrical signal to be sent to the device by the photoelectric conversion module. Specifically, the second measuring device is pre-configured with a receiving compensation parameter list as shown in Table 13:

[0307] Table 13

[0308] Receive compensation parameter 1 Receive compensation parameter 2 Receive compensation parameter 3 …… Receive compensation parameter P

[0309] As shown in Table 13, the reception compensation parameter list stored in the second measuring device includes P reception compensation parameters, namely reception compensation parameter 1, reception compensation parameter 2 to reception compensation parameter P, and P shown in this embodiment is an arbitrary integer greater than or equal to 1. The second measuring device simulates and compensates for different degrees of insertion loss of the electrical signal transmitted by the RX channel of the photoelectric conversion module according to the reception compensation parameters with different values ​​shown in Table 13.

[0310] For an explanation of the values ​​of the P receiving compensation parameters, see Figure 5 The description of the corresponding J transmission compensation parameter values ​​is not detailed here. The first receiving compensation parameter is one of the P receiving compensation parameters shown in Table 13. For example, if the first receiving compensation parameter is XdB, the second measuring device will simulate the photoelectric conversion module to compensate for the insertion loss of XdB for the electrical signal to be sent to the device to suppress ISI. The second measuring device compensates the second measured electrical signal according to the first receiving link parameter to obtain the first indicator electrical signal.

[0311] Step 1305: The second measuring device detects that the bit error rate of the first indicator electrical signal is within a preset bit error rate range.

[0312] The second measuring instrument shown in this embodiment includes an adjustable attenuator that gradually adjusts the attenuation value to gradually adjust the optical power of the received optical signal after the first attenuation until the second measuring device detects that the bit error rate corresponding to the first indicator electrical signal is within a preset bit error rate range.

[0313] Step 1306 , the second measuring device determines whether the first receiving performance indicator is within the receiving performance indicator range, if not, execute step 1307 , if yes, execute step 1310 .

[0314] For the description of the execution process of step 1306 shown in this embodiment, please refer to step 1206, and the details are not repeated here.

[0315] Optionally, after obtaining the first receiving performance indicator, the second measuring device may obtain three different first receiving side indicator lists:

[0316] For example, as shown in Table 14, the second receiving side indicator list shown in Table 14 creates a correspondence between N receiving link parameters and N receiving performance indicators corresponding to each receiving compensation parameter among P receiving compensation parameters.

[0317] Table 14

[0318]

[0319] The second receiving side indicator list shown in Table 14 creates a correspondence between each receiving compensation parameter, each receiving link parameter, and the receiving performance indicator. If the first receiving compensation parameter shown above is the receiving compensation parameter P, and the first receiving link parameter is the receiving link parameter 1, then the receiving performance indicator obtained by the second measurement device is the receiving performance indicator 1, and the second measurement device can store the correspondence between the receiving compensation parameter P, the receiving link parameter 1, and the receiving performance indicator 1 in the second receiving side indicator list shown in Table 14.

[0320] For another example, as shown in Table 15, the third receiving side indicator list shown in Table 15 creates a correspondence between N receiving link parameters and N receiving performance indicators corresponding to each receiving channel compensation parameter among K receiving channel compensation parameters.

[0321] Table 15

[0322]

[0323] In order to reduce power consumption and suppress ISI, the photoelectric conversion module can compensate the electrical signal to be sent to the device according to one of the K receiving channel compensation parameters, thereby improving the quality of the electrical signal output by the photoelectric conversion module and reducing the bit error rate. The second measuring device pre-stores the K receiving channel compensation parameters used by the photoelectric conversion module to compensate for the electrical signal, and K shown in this embodiment is an arbitrary integer greater than or equal to 1. The photoelectric conversion module compensates the electrical signal to be sent to the second measuring device according to the different receiving channel compensation parameters shown in Table 15 to compensate for the different degrees of insertion loss of the electrical signal.

[0324] If the second measuring device determines that the optoelectronic conversion module currently compensates for the electrical signal based on the first receiving channel compensation parameter (for example, the first receiving channel compensation parameter is the receiving channel compensation parameter K), then the second measuring device determines that the first receiving link parameter is the receiving link parameter 1, and the first receiving performance indicator obtained by the second measuring device is the receiving performance indicator 1. The second measuring device stores the correspondence between the receiving channel compensation parameter K, the receiving link parameter 1 and the receiving performance indicator 1 in the third receiving side indicator list shown in Table 15.

[0325] For example, as shown in Table 16, the fourth receiving side indicator list shown in Table 16 creates a correspondence between P receiving compensation parameters, N receiving link parameters and N receiving performance indicators corresponding to each receiving channel compensation parameter in K receiving channel compensation parameters.

[0326] Table 16

[0327]

[0328]

[0329] In the fourth receiving side indicator list shown in Table 16, for the description of the K receiving channel compensation parameters, please refer to the corresponding description of Table 14, and for the description of the P receiving compensation parameters, please refer to the corresponding description of Table 15, and the details will not be repeated here.

[0330] If the second measuring device determines that the optoelectronic conversion module currently compensates for the electrical signal based on the first receiving channel compensation parameter (for example, the first receiving channel compensation parameter is the receiving channel compensation parameter K), and the second measuring device compensates for the electrical signal from the optoelectronic conversion module based on the receiving compensation parameter P, and the first receiving link parameter is the receiving link parameter 1, then the first receiving performance indicator obtained by the second measuring device is the receiving performance indicator 1, and the second measuring device can store the correspondence between the receiving channel compensation parameter K, the receiving compensation parameter P, the receiving link parameter 1 and the receiving performance indicator 1 in the fourth receiving side indicator list shown in Table 16.

[0331] The second measurement device shown in this embodiment pre-configures the reception performance index range. When the first reception performance index range is within the reception performance index range, it means that the RX channel of the photoelectric conversion module meets the quality standard under the first reception link parameters. If the first reception performance index is not within the reception performance index range, it means that the quality of the RX channel of the photoelectric conversion module does not meet the quality standard under the first reception link parameters.

[0332] Step 1307 : The second measuring device determines whether the compensation traversal condition is met, and if so, executes step 1308 ; if not, executes step 1309 .

[0333] In this embodiment, the compensation traversal conditions are different as the receiving side indicator list stored in the second measuring device is different.

[0334] For example, if the second measurement device stores a second receiving side indicator list as shown in Table 14, satisfying the compensation traversal condition means that the second measurement device obtains N receiving link parameters and N receiving performance indicators corresponding to each receiving compensation parameter among P receiving compensation parameters. For another example, if the second measurement device stores a third receiving side indicator list as shown in Table 15, satisfying the compensation traversal condition means that the second measurement device obtains N receiving link parameters and N receiving performance indicators corresponding to each receiving channel compensation parameter among K receiving channel compensation parameters. For another example, if the second measurement device stores a fourth receiving side indicator list as shown in Table 16, satisfying the compensation traversal condition means that the second measurement device obtains P receiving compensation parameters, N receiving link parameters and N receiving performance indicators corresponding to each receiving channel compensation parameter among K receiving channel compensation parameters. This embodiment takes the example that the second measurement device creates the fourth receiving side indicator list as shown in Table 16.

[0335] Step 1308: The second measuring device determines that the RX channel of the photoelectric conversion module does not meet the quality standard.

[0336] Step 1309: The second measuring device obtains a second receiving compensation parameter and a second receiving channel compensation parameter.

[0337] When the second measuring device shown in this embodiment obtains the second receiving compensation parameter and the second receiving channel compensation parameter, the second measuring device updates the first receiving compensation parameter to the second receiving compensation parameter, and the second measuring device compensates the electrical signal from the photoelectric conversion module according to the second receiving compensation parameter. The second measuring device also sends the second receiving channel compensation parameter to the photoelectric conversion module, and the photoelectric conversion module updates the first receiving channel compensation parameter to the second receiving channel compensation parameter, and the photoelectric conversion module compensates the electrical signal to be sent to the second measuring device according to the second receiving channel compensation parameter.

[0338] Step 1310 : The second measuring device determines whether the RX channel traversal condition is met, and if so, executes step 1311 ; if not, executes step 1314 .

[0339] Meeting the RX channel traversal condition shown in this embodiment means that the second measurement device has obtained the receiving performance indicator corresponding to each receiving link parameter in the N receiving link parameters. If so, execute step 1310, if not, execute step 1311.

[0340] Step 1311: The second measuring device determines whether the RX channel of the photoelectric conversion module meets the quality standard.

[0341] Step 1312: The second measuring instrument sends a second measuring light signal to the photoelectric conversion module.

[0342] Step 1313: The photoelectric conversion module sends a fifth measurement electrical signal to the second measurement device.

[0343] Step 1314: The second measurement device attenuates the fifth measurement electrical signal according to the second receiving link parameter to obtain a sixth measurement electrical signal.

[0344] For a description of the execution process of steps 1312 to 1314 shown in this embodiment, please refer to Fig.12 The corresponding description of the execution process of step 1201 to step 1203 is not repeated in detail.

[0345] Step 1315: The second measuring device compensates the sixth measurement electrical signal according to the second receiving compensation parameter and / or the receiving channel compensation parameter to obtain a second index electrical signal.

[0346] Step 1316: The second measuring device detects that the bit error rate of the second indicator electrical signal is within a preset bit error rate range.

[0347] Step 1317: The second measuring device determines whether the second receiving performance indicator is within the receiving performance indicator range. If not, the process returns to step 1307; if so, the process returns to step 1310.

[0348] Using the method shown in this embodiment, the second measuring device compensates the electrical signal from the optoelectronic conversion module according to the receiving compensation parameter, thereby simulating the compensation of the electrical signal from the optoelectronic conversion module by the RX channel of the device. The second measuring device also simulates one or more effects such as insertion loss, crosstalk or reflection brought by the RX channel of the device to the electrical signal by attenuating the amplitude of the electrical signal from the optoelectronic conversion module. Moreover, the second measuring device can compensate the electrical signal separately according to different receiving compensation parameters, and the second measuring device can attenuate the electrical signal from the optoelectronic conversion module separately according to different receiving link parameters, so that the second measuring device can simulate various possible link conditions of the RX channel of the device, and then measure the quality of the RX channel of the optoelectronic conversion module under different link conditions, thereby improving the accuracy of the quality measurement of the optoelectronic conversion module.

[0349] Fig.14 This is a flowchart of the execution steps of the sixth embodiment of the measurement method provided in this application. In the measurement method shown in this embodiment, the second measurement device can simulate the different degrees of influence of the RX channel of the device on the electrical signal from the photoelectric conversion module, simulate the various compensations of the RX channel of the device and the photoelectric conversion module on the electrical signal, and obtain the corresponding receiving configuration information. For a description of the measurement system used by the method shown in this embodiment, please refer to Fig.11 The corresponding instructions are not elaborated in detail.

[0350] Step 1401: The second measuring instrument sends a first measuring light signal to the photoelectric conversion module.

[0351] Step 1402: The photoelectric conversion module sends a first measurement electrical signal to a second measurement device.

[0352] Step 1403: The second measurement device attenuates the first measurement electrical signal according to the first receiving link parameter to obtain a second measurement electrical signal.

[0353] Step 1404: The second measuring device compensates the second measurement electrical signal according to the first received compensation parameter to obtain a first indicator electrical signal.

[0354] Step 1405: The second measuring device detects that the bit error rate of the first indicator electrical signal is within a preset bit error rate range.

[0355] For a description of the execution process of steps 1401 to 1405 shown in this embodiment, please refer to Fig.13 The corresponding steps 1301 to 1305 are described in detail, and the specific execution process is not repeated.

[0356] Step 1406: The second measuring device obtains the target corresponding relationship when the compensation traversal condition is met.

[0357] In this embodiment, the compensation traversal conditions are different as the receiving traversal list stored in the second measuring device is different.

[0358] The second measurement device shown in this embodiment can pre-store three different receiving traversal lists.

[0359] For example, as shown in the first receiving traversal list in Table 17, the first receiving traversal list shown in Table 17 is used to create a corresponding relationship between the bit error rate corresponding to each receiving compensation parameter among P receiving compensation parameters.

[0362] For a description of the P receive compensation parameters, see Fig.12 If the first receiving compensation parameter shown above is the receiving compensation parameter P, then the first bit error rate obtained by the second measuring device is the bit error rate P, and the second measuring device can store the corresponding relationship between the receiving compensation parameter P and the bit error rate P in the first receiving traversal list shown in Table 17.

[0363] For another example, as shown in the second receiving traversal list in Table 18, the second receiving traversal list shown in Table 18 creates a corresponding relationship between the bit error rate corresponding to each receiving channel compensation parameter among the K receiving channel compensation parameters.

[0364] Table 18

[0365] Receive channel compensation parameters Bit Error Rate Receive channel compensation parameter 1 Bit Error Rate 1 Receive channel compensation parameter 2 BER2 …… …… Receiving channel compensation parameter K Bit Error Rate K

[0366] For a description of the compensation parameters for the K receiving channels, see Fig.13 The corresponding instructions are not described in detail. The above-mentioned photoelectric conversion module compensates the electrical signal to be sent to the second measuring device according to the first receiving channel compensation parameter (for example, the first receiving channel compensation parameter is the receiving channel compensation parameter K). Then, the first bit error rate obtained by the second measuring device is the bit error rate K, and the second measuring device can store the corresponding relationship between the receiving channel compensation parameter K and the bit error rate K in the second receiving traversal list shown in Table 18.

[0367] For another example, as shown in the third receiving traversal list in Table 19, the third receiving traversal list shown in Table 19 creates a correspondence between P receiving compensation parameters corresponding to each receiving channel compensation parameter in the K receiving channel compensation parameters and P bit error rates.

[0368] Table 19

[0369]

[0370] If the first receiving compensation parameter shown above is the receiving compensation parameter P, and the photoelectric conversion module compensates the electrical signal to be sent to the second measuring device according to the first receiving channel compensation parameter (for example, the first receiving channel compensation parameter is the receiving channel compensation parameter K), then the first bit error rate obtained by the second measuring device is the bit error rate P, and the second measuring device can store the correspondence between the receiving channel compensation parameter K, the receiving compensation parameter P and the bit error rate P in the third receiving traversal list shown in Table 19.

[0371] If the second measuring device stores the first receiving traversal list as shown in Table 17, satisfying the compensation traversal condition means that the second measuring device has obtained the bit error rate corresponding to each receiving compensation parameter among the P receiving compensation parameters. For another example, if the second measuring device stores the second receiving traversal list as shown in Table 18, satisfying the compensation traversal condition means that the second measuring device has obtained the bit error rate corresponding to each receiving channel compensation parameter among the K receiving channel compensation parameters. For another example, if the second measuring device stores the third receiving traversal list as shown in Table 19, satisfying the compensation traversal condition means that the second measuring device has obtained P receiving compensation parameters and P bit error rates corresponding to each receiving channel compensation parameter among the K receiving channel compensation parameters. This embodiment takes the example that the second measuring device has created the third receiving traversal list as shown in Table 19.

[0372] The target correspondence shown in this embodiment includes the correspondence between the target receiving channel compensation parameter, the target receiving compensation parameter and the target bit error rate. The target bit error rate shown in this embodiment is the minimum value of the multiple bit error rates shown in the receiving traversal list. For example, if the second measuring device stores the first receiving traversal list shown in Table 17, the target bit error rate is the minimum value of the multiple bit error rates shown in Table 17. For another example, if the second measuring device stores the second receiving traversal list shown in Table 18, the target bit error rate is the minimum value of the multiple bit error rates shown in Table 18. For another example, if the second measuring device stores the third receiving traversal list shown in Table 19, the target bit error rate is the minimum value of the multiple bit error rates shown in Table 19.

[0373] It should be noted that this embodiment takes the target bit error rate as the minimum value of multiple bit error rates shown in the received traversal list as an example, and is not limited thereto. For example, the target bit error rate may be any value within the preset bit error rate range.

[0374] In this embodiment, the second measuring device obtains the target receiving compensation parameter and the target receiving channel compensation parameter. The target receiving compensation parameter and the target receiving channel compensation parameter are used to enable the second measuring device to obtain the target bit error rate. For example, in the third receiving traversal list shown in Table 19, when the receiving compensation parameter of the second measuring device is the receiving compensation parameter P and the receiving channel compensation parameter of the photoelectric conversion module is the receiving channel compensation parameter K, the corresponding bit error rate is the smallest and is the bit error rate P. Then, the second measuring device obtains the target corresponding relationship, which includes the corresponding relationship between the target receiving channel compensation parameter K, the target receiving compensation parameter P and the target bit error rate P.

[0375] Step 1407: The second measuring device obtains a target receiving performance indicator.

[0376] When the second measuring device updates the receiving compensation parameter of the second measuring device to the target receiving compensation parameter, and updates the receiving channel compensation parameter of the optoelectronic conversion module to the target receiving channel compensation parameter, the second measuring device obtains the target receiving performance indicator. Specifically, this embodiment takes the target receiving performance indicator as the receiver sensitivity (OMAouter) as an example. When the bit error rate of the received optical signal after the first attenuation is within the preset bit error rate range, the target receiving performance indicator is obtained according to the optical power value on the optical power meter of the second measuring instrument and the extinction ratio of the optical transmitter of the second measuring instrument. For a description of the specific obtaining process, please refer to Fig.12 As shown in the corresponding step 1205, the details are not repeated.

[0377] Step 1408 , the second measuring device determines whether the target reception performance indicator is within the reception performance indicator range, if not, execute step 1409 , if yes, execute step 1410 .

[0378] Step 1409: The second measuring device determines that the RX channel of the photoelectric conversion module does not meet the quality standard.

[0379] Step 1410: The second measurement device obtains receiving configuration information.

[0380] In this embodiment, the receiving configuration information includes the target corresponding relationship, and the receiving configuration information also includes the target receiving performance indicator and the first receiving link parameter. It can be understood that the receiving configuration information can be shown in Table 20:

[0381] Table 20

[0382]

[0383] That is, when the target receiving link parameter, the target receiving channel compensation parameter and the target receiving compensation parameter are respectively the first receiving link parameter, the target receiving channel compensation parameter K and the target receiving compensation parameter P, the second measuring device can obtain the target receiving performance indicator within the receiving performance indicator range.

[0384] In this embodiment, the receiving configuration information includes the target receiving link parameter, the target receiving channel compensation parameter, the target receiving compensation parameter, and the target receiving performance index as an example. In other examples, the receiving configuration information may include the target receiving link parameter and the target receiving performance index. For another example, the receiving configuration information may include the target receiving link parameter, the target receiving module compensation parameter, and the target receiving performance index. For another example, the receiving configuration information may include the target receiving link parameter, the target receiving compensation parameter, and the target receiving performance index.

[0385] Step 1411 : The second measuring device determines whether the RX channel traversal condition is met, and if so, executes step 1412 ; if not, executes step 1415 .

[0386] For a description of the execution process of step 1411 shown in this embodiment, see Fig.12 The corresponding step is shown in step 1208 and will not be described in detail.

[0387] Step 1412: The second measuring device determines whether the RX channel of the photoelectric conversion module meets the quality standard.

[0388] Step 1413: The second measuring instrument sends a second measuring light signal to the photoelectric conversion module.

[0389] Step 1414: The photoelectric conversion module sends a fifth measurement electrical signal to the second measurement device.

[0390] Step 1415: The second measuring device attenuates the amplitude of the fifth measurement electrical signal according to the second receiving link parameter to obtain a sixth measurement electrical signal.

[0391] Step 1416: The second measuring device compensates the fifth measurement electrical signal according to the first received compensation parameter to obtain a second indicator electrical signal.

[0392] Step 1417 : The second measuring device detects that the bit error rate of the second indicator electrical signal is within a preset bit error rate range, and returns to execute step 1406 .

[0393] For the description of the execution process of steps 1413 to 1417 shown in this embodiment, please refer to the description of the execution process of steps 1401 to 1405, and the details are not repeated here.
