[0045] The embodiment of the present application provides a kind of optical module measurement device, as shown in Figure 1 It includes test module, power management module and temperature management module;The test module is provided with multiple connecting seats and multiple fans.

[0046] The first output end (i.e. Figure 1 1-1 port and 2-2 port in) of the power management module is connected with the power supply end (i.e. Figure 1 5-1 port and 5-2 port in) of each connecting seat;The second output end (i.e. Figure 1 2 port in) of the power management module is connected with the power supply end (i.e. Figure 1 3 port in) of the temperature management module;The output end (i.e. Figure 1 4-1 port and 4-2 port in) of the temperature management module is connected with the control end of each fan.

[0047] The connecting seat is used to install optical module;The power management module is used to provide first working voltage for optical module, and second working voltage for temperature management module;The temperature management module is used to provide driving current for fan, to drive fan rotation, realize temperature control to optical module. Wherein, the size of the driving current can be obtained by those skilled in the art according to test demand analysis.

[0048] Among them, the connecting seat is one or more of Quad Small Form Factor Pluggable-Double Density (QSFP-DD for short) connecting seat, Octal Small Formfactor Pluggable (OSFP for short) connecting seat and Centum Form-factor Pluggable (CFP) connecting seat.

[0049] It needs to be explained here that, Figure 1is exemplified by setting 2 connection seats (connection seat 1 and connection seat 2) and 2 fans (fan 1 and fan 2) on the test module, in actual use, the number N of connection seats set on one test module is obtained by demand analysis by those skilled in the art, and N fans are correspondingly set, so that each fan controls the temperature of the corresponding connection seat, in actual use, the test module can also be provided with multiple air ducts, each connection seat is arranged in an air duct, and a corresponding fan is arranged at the opening position of the air duct.

[0050] On the one hand, the embodiment can be used for testing of multiple optical modules by setting multiple connection seats on the test module, and on the other hand, the embodiment also sets a fan in the test module, and uses a temperature management module to provide driving current for the fan, so as to realize temperature control of the optical module, thereby meeting the testing requirements of the optical module at a specific temperature.

[0051] It is considered that in actual use, not only the optical module itself needs to be tested, but also the communication between multiple optical modules needs to be tested, in order to meet this requirement, the embodiment also provides a preferred implementation, that is, as shown in Figure 2 , the electrical interfaces (i.e. 6-1 port and 6-2 port in Figure 2 ) between every two connection seats are connected to each other to form a data transmission channel between the corresponding two optical modules.

[0052] Exemplified by taking the connection seat 1 and the connection seat 2 as QSFP-DD connection seats, then one connection seat has 8 electrical interfaces, the 8 electrical interfaces of the connection seat 1 are connected to the 8 electrical interfaces of the connection seat 2 in sequence to form a lane transmission, wherein each pair of connections supports a 56 baud rate.

[0053] In this embodiment, the tested optical module (i.e. the optical module that has been tested and has normal function) can be installed on the connection seat 1 as a communication module, the to-be-tested optical module (i.e. the optical module that needs to be tested) is installed on the connection seat 2, and the optical interface of the to-be-tested optical module is connected to other optical modules through an optical transmission system, so that the indicators of the to-be-tested optical module can be tested through the optical interface of the communication module. Figure 3For example, the measured optical module is installed in the connection seat 1 as a communication module, the optical interface of the communication module is connected to the error code instrument, the optical module to be measured is installed in the connection seat 2, and the optical module to be measured is connected to other optical modules through the optical transmission system. The other optical modules can be optical modules to be measured, so as to test the communication between the two optical modules to be measured, or can be measured optical modules, that is, only one optical module to be measured and the existing optical module are tested. In actual testing, optical communication is carried out between the other optical modules and the optical module to be measured, the communication data is converted into an electrical signal, and then transmitted to the communication module through the data transmission channel, and then transmitted to the error code instrument for testing, so as to obtain the bit error rate in the optical communication process. The communication module can be understood as a module with a reliable bit error rate in a controllable range, so as to not affect the test of the optical communication process.

[0054] In a specific application scenario, as shown in Figure 4 The power management module includes a power supply unit and a voltage conversion unit; each first output end (i.e. 7-1 port and 7-2 port in Figure 4 ) of the power supply unit is connected to the input end of each voltage conversion unit; the output end of each voltage conversion unit is used as the first output end of the power management module; the second output end (i.e. 8 port in Figure 4 ) of the power supply unit is used as the second output end of the power management module; the power supply unit is used to generate an original voltage, and the original voltage is used as a second working voltage; the voltage conversion unit is used to convert the original voltage into the first working voltage. In a specific application scenario, the size of the original voltage can be 12V, and the size of the first working voltage is 3.2-3.4V. In an optional embodiment, the size of the first working voltage is 3.3V.

[0055] In a preferred embodiment, as shown in Figure 5 The power management module further includes a plurality of voltage and current detection units; each voltage and current detection unit is arranged between the corresponding voltage conversion unit and the connection seat; the voltage and current detection unit is used to detect the size of each first working voltage and the size of the first working current, so as to detect the power consumption of the optical module through the size of the first working voltage and the size of the first working current; wherein the first working current is the current input to the power supply end of each connection seat.

[0056] The power consumption of the optical module can be calculated by a person skilled in the art according to the detected size of the first working voltage and the size of the first working current.

[0057] In an optional embodiment, as shown in Figure 6 It further includes a transmission module; the power supply end (i.e. 9 port in Figure 6The 10 port in the power supply module and the third output terminal (i.e., port 10) are connected to the third output terminal of the power supply module. Figure 6 The first port of the transmission module (i.e., port 9) is connected to provide power to the transmission module; Figure 6 The 13th port of the transmission module is connected to the host computer, and each of the second ports of the transmission module (i.e., ...) Figure 6 Ports 11-1 and 11-2 of the optical module are connected to the command communication terminals of each connector (in actual use, these are represented by the I2C pins of each connector). In a specific application scenario, the transmission module also reserves an additional port, which is connected to the low-power pins of each connector, enabling the optical module to be controlled by a hardware DIP switch and also by a host computer through the transmission module. The transmission module is used to receive optical module control commands from the host computer and send the optical module control commands to each optical module.

[0058] In a preferred embodiment, the third port of the transmission module (i.e. Figure 6 The transmission module (port 13) is connected to the command communication terminal of the temperature management module; the transmission module is used to receive temperature control commands from the host computer and send the temperature control commands to the temperature management module. The transmission module also reads the temperature of each optical module (i.e., the case temperature of the optical module) from the command communication terminal and reports the temperature of each optical module to the host computer so that the host computer can send temperature control commands according to the temperature of the optical modules.

[0059] In practical use, such as Figure 7 As shown, each fourth port of the transmission module is also connected to the output terminal of each voltage and current detection unit to receive the magnitude of the first operating voltage and the magnitude of the first operating current detected by the voltage and current detection units, and transmit the magnitude of the first operating voltage and the magnitude of the first operating current to the host computer; each fifth port of the transmission module is also connected to the control terminal of each voltage conversion unit to receive voltage control commands from the host computer, and send the voltage control commands to each voltage conversion unit to control the magnitude of the output first operating voltage. In this preferred embodiment, temperature and voltage control of each optical module can be realized, thereby enabling the optical module to be tested in a stable three-temperature and three-wave environment.

[0060] The transmission module may include a microcontroller and a network connection unit (such as a network management module and a network port connector), thereby enabling data transmission between the microcontroller and the host computer. The network connection unit may be a wired network connection unit or a wireless network connection unit; this embodiment does not impose any limitation on this.

[0061] The following will be based on the above method, combined with specific application scenarios, and by the technical expression in the relevant scene to elaborate the implementation process of the characteristic scene of the utility model. This embodiment is to set two connecting seats on the test module, and the two connecting seats are QSFP-DD connecting seats.

[0062] As shown in Figure 8 and Figure 9 , the optical module debugging device of the embodiment includes a power management module, a test module, a temperature management module, a transmission module (including a central processing unit (CPU) control small system, i.e. a single-chip microcomputer, and a network connection unit), and an external host computer and an optical path test platform (i.e. an index detection device) of the optical module debugging device. Among them, Figure 9 The use of the error code instrument to test the to-be-tested optical module in the optical module debugging device is used as an application scenario, and it should be noted that in actual use, the fan is located close to the connecting seat, i.e. on the test module, Figure 9 The fan in the test module is placed outside the test module only for the clarity of the connection relationship in the drawing, and does not represent the actual position of the fan.

[0063] The power management module is powered by a common 220V power line for a pluggable power module, and the 1200W pluggable power module is connected to the 12V power supply (i.e. the 12V power supply unit in Figure 9 ) can be connected to four test boards in four ways (this function is realized by the power supply unit). The 12V power supply is supplied to the test board to supply power to the temperature management module, and is converted to 3.3V by the DC / DC voltage conversion module to supply power to the single-chip microcomputer and the to-be-tested optical module, wherein two to-be-tested optical modules are provided with current and voltage monitoring chips (i.e. voltage and current detection units) in front of them for module power consumption detection.

[0064] The test module has two QSFP-DD connecting seats for plugging and unplugging QSFP-DD modules and has good heat dissipation, which can solve the heat dissipation of 25W power consumption. The two to-be-tested optical module electrical ports (i.e. electrical interfaces) have 8 pairs of lane pairs on the board, and each pair can support a 56G baud rate.

[0065] The single-chip microcomputer in the transmission module can fetch the temperature of the module every 5 seconds, and adjust the duty cycle of the fan speed control chip according to the set value to achieve the effect of temperature control

[0066] The CPU control small system is a 3.3V powered single-chip microcomputer, and the low-power pins of the to-be-tested optical module are led to the board, one side is controlled by a hardware dial switch, and the other side is controlled by a single-chip microcomputer. In addition, the I2C pin of the to-be-tested optical module is also connected to the single-chip microcomputer for issuing commands to the module

[0067] The network connection unit includes a network port control and a serial port control, and the serial port is often used to obtain the printing information of the optical module. The test board has two network ports for network port cascading. The host computer can simultaneously control multiple optical module test devices.

[0068] The host computer is a computer terminal commonly used by people, and the host computer can simultaneously operate the optical module test devices to test the optical modules.

[0069] The optical path test platform can be switched according to test requirements. For example, when a factory-hung test is performed, two test ports are used, one of which can be connected to a data module on an error code instrument, and the other can be connected to a fiber passing through a DWDM system to form a loop. For example, when the light output parameters of the optical module to be tested are tested, the wavelength meter is connected to test the light output accuracy, and the optical switch is connected to the optical spectrum analyzer to read the TX OSNR.

[0070] In the prior art, there are related patents with publication numbers CN203691398U and CN202798726U. However, the CN203691398U patent mainly uses an external power supply to supply power to the test board, and uses the host computer to debug the CFP2 packaged optical module, and the high-speed signal interface of the module is led out for high-speed electrical signal measurement.

[0071] The difference between the embodiment and the prior art is that the electrical signal of the embodiment is in a transmission state on the test module rather than being led out for measurement, and the test items of the embodiment are biased towards optical testing. Moreover, the embodiment specially supports the testing of QSFP-DD packaged optical modules, and the embodiment supports temperature control of the optical module.

[0072] The difference between the embodiment and the CN202798726U patent is that the embodiment specially supports the testing of QSFP-DD packaged optical modules, and the CN202798726U patent leads out the MDIO interface, the control pin interface, and the test signal interface, which is more biased towards electrical signal testing. The embodiment mainly tests the optical indicators of the module, and controls the working environment (i.e., the temperature) of the optical module.

[0073] The optical module test device described in the embodiment uses a low-cost test board rather than a switch as a fixture, which greatly saves the testing cost of the product. The temperature, voltage, current, and power consumption can be accurately controlled in real time, the temperature and voltage of the module can be controlled, and automatic five-angle polarization testing can be realized. Multiple systems can be simultaneously tested through network port multi-level cascading, which improves the testing efficiency. Two QSFP-DD packaged modules can be wired on the test module to achieve good electrical port transmission, which can serve as a fixture for the module before it is shipped.

[0074] Compared with the prior art, the embodiment can accurately control temperature, voltage, current and power consumption in real time, control temperature and voltage of the module, realize automatic five-angle polarization test, realize simultaneous test of multiple systems through multi-level cascade, improve test efficiency, support test and debugging of QSFP-DD packaged optical modules, and multiple projects share the test platform. The embodiment can also simultaneously realize electrical port and optical port performance test functions. The embodiment also uses an upper computer GUI interface for control, facilitates automatic test, and can cascade test platforms to improve test efficiency.

A test input end of the index detection device is connected with an optical interface of each optical module to be tested to detect indexes of each optical module to be tested. The index detection device can be a bit error rate tester, a wavelength meter or a spectrometer.

[0077] Taking the index detection device as a bit error rate tester as an example, as shown in Figure 8 Two connection seats are arranged on the test module, and the two connection seats are QSFP-DD connection seats. As shown in Figure 9 The power management module, the test module, the temperature management module and the CPU control subsystem are all controlled through I2C communication. The upper computer inputs target temperature, voltage parameters and configuration information instructions. The CPU issues initialization temperature and voltage instructions. The optical module to be tested is started. The module temperature is read back and displayed. The fan speed is increased or decreased. If the temperature is greater than the set value, the speed continues to increase. Otherwise, the speed is decreased. Until the temperature = set value ± 0.5℃. Similarly, the module voltage, current and calculated power consumption are read back and displayed. If the voltage is greater than the set value, the DC / DC output voltage is decreased. If the module voltage is less than the set value, the DC / DC output voltage is increased. Until the voltage = set value ± 0.01V, a stable test environment is achieved to start the test.
