[0160] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0161] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0162] To facilitate understanding, the technical terms involved in the embodiments of this application will be explained first.

[0163] (1) Passive Optical Network (PON)

[0164] PON is the primary technology used in fiber optic broadband access. The following section combines... Figure 1 The PON system will be explained.

[0165] Figure 1 This is a schematic diagram of a PON system architecture provided for an embodiment of this application. Please refer to [link / reference]. Figure 1 A PON system may include an optical line terminal (OLT), an optical distribution network (ODN), and at least one optical network unit (ONU) (e.g., Figure 1 (ONU1, ONU2, and ONU3). ONU can also be called "optical modem" or user terminal equipment. OLT can also be called central office equipment.

[0166] In one embodiment, the number of ONUs in the PON system can be one or more, but this application does not limit this.

[0167] The Optical Fiber Access Terminal (OLT) is the core equipment in the optical fiber access network, located at the operator's central office. The Optical NU (ONU) is the user-side equipment in the optical fiber access network. The OLT can connect to the ONU through the Optical Distribution Network (ODN), and the ODN can provide optical transmission channels for both the OLT and the ODN.

[0168] In the above system architecture, downlink optical signals (optical signals from the OLT to the ONUs) can be transmitted via broadcast. Specifically, the OLT can send downlink optical signals to the ODN. After receiving the downlink optical signals, the ODN can broadcast the downlink optical signals to all ONUs connected to it. All ONUs connected to the ODN can receive their own downlink optical signals from the ODN and discard downlink optical signals that do not belong to them. Uplink optical signals (optical signals from the ONUs to the OLT) can be transmitted via Time Division Multiple Access (TDMA). Specifically, each ODN can send optical signals to the OLT in different time slots.

[0169] (2) ONU optical components

Figure 2 The ONU optical components may include a transmitter optical subassembly (TOSA) and a receiver optical subassembly (ROSA) peripheral driving unit, etc. The TOSA may include a laser diode (LD) and a monitor photodiode (MPD).

[0172] It should be noted that, Figure 2 The structure of the ONU optical component is illustrated only and does not constitute a limitation on the ONU optical component. The ONU optical component may also include more or fewer components than illustrated.

[0173] In the aforementioned ONU optical module, the ROSA peripheral drive module can apply a suitable drive current to the TOSA to enable the LD to emit an optical signal. The optical signal emitted by the LD is coupled forward through a lens to the optical port output of the ONU optical module (not shown in the figure). The intensity of the optical signal output from the optical port is the actual emitted optical power of the ONU optical module. The optical signal emitted by the LD is back-illuminated onto the MPD, forming the incident optical signal of the MPD. After the incident optical signal of the MPD is formed, the MPD can generate a current based on the photoelectric effect. The magnitude of the current generated by the MPD is proportional to the emitted optical power of the incident optical signal of the MPD. Thus, the magnitude of the current generated by the MPD can reflect the intensity of the incident optical signal of the MPD, and further reflect the intensity of the optical signal emitted by the LD (i.e., the actual emitted optical power of the ONU optical module). This allows for real-time monitoring of the actual emitted optical power of the ONU optical module through the MPD.

[0174] (3) Transmitted optical power of ONU optical components

[0175] Ideally, when the current applied to the LD in the ONU optical component is less than its laser threshold current, the emitted light power of the LD is small, and it can be assumed that the LD does not emit light, and thus the ONU optical component does not emit light.

[0176] Figure 3 This is a graph showing the emitted optical power of an ONU optical component provided in an embodiment of this application. Please refer to [link / reference]. Figure 3 The horizontal axis represents the current applied to the LD, and the vertical axis represents the emitted optical power of the LD.

[0177] It should be noted that the current applied to the LD can also be referred to as the current applied to the ONU optical component. The emitted optical power of the LD can be referred to as the actual emitted optical power of the ONU optical component.

[0178] like Figure 3 As shown, Ith is the threshold current of the ONU optical component, I 偏置 I is the bias current applied to the ONU optical component. 调制 The modulation current applied to the ONU optical component. Only in I... 偏置 The ONU optical component will only emit light normally when the current is greater than Ith. When only a bias current is applied to the ONU optical component and only a code "0" (i.e., a low-level signal) is sent to the ONU optical component, the emitted optical power of the ONU optical component is P0; when a bias current is applied to the ONU optical component and only a code "1" (i.e., a high-level signal) is sent to the ONU optical component, the emitted optical power of the ONU optical component is P1.

[0179] The actual emitted optical power of an ONU optical component generally refers to the average value of P0 and P1.

[0180] The communication method provided in this application can be applied to scenarios where ONU optical components communicate with OLT. When the ONU optical component communicates with the OLT, it sends an optical signal to the OLT. Correspondingly, the OLT receives the optical signal sent by the ONU optical component. When the strength of the optical signal received by the OLT is less than the receiving sensitivity of the OLT optical module, it may cause problems such as CRC errors, high BER, or packet loss in the OLT's optical signal reception, resulting in poor communication quality between the ONU optical component and the OLT.

[0181] This application proposes the following technical concept: When the OLT experiences an optical signal reception anomaly, and the monitored value of the actual transmitted optical power of the ONU optical component does not exceed the upper limit of the ONU optical component's transmitted optical power (e.g., the actual transmitted optical power of the ONU optical component is low), the OLT can instruct the ONU optical component to adjust its actual transmitted optical power. Correspondingly, the ONU optical component can automatically adjust its actual transmitted optical power according to the OLT's instruction. This maintains the actual transmitted optical power of the ONU optical component at an appropriate level, preventing deterioration in system communication quality due to a low actual transmitted optical power. The upper limit of the ONU optical component's transmitted optical power can be the specified upper limit of the monitored transmitted optical power value, or the theoretical maximum value of the monitored transmitted optical power value, etc.

[0182] In addition, in the technical solution provided in this application embodiment, the OLT and ONU optical components can automatically adjust the actual transmitted optical power of the ONU optical component, eliminating the need for manual adjustment of the actual transmitted optical power of the ONU optical component, thereby improving the level of intelligent operation and maintenance of the optical network and greatly saving manual operation and maintenance costs.

[0183] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0184] Figure 4 This is a flowchart illustrating a communication method provided in an embodiment of this application. The executing entity of this method can be an OLT (Optical Line Transport Unit) or a communication device located within the OLT. The communication device can be implemented through software or a combination of software and hardware. For ease of understanding, the following explanation uses an OLT as the executing entity. Please refer to... Figure 4 The method may include:

[0185] S401. When the optical signal reception is abnormal, obtain the monitoring value of the actual transmitted optical power of the ONU optical component.

[0186] The ONU optical component can be the light-emitting module in the ONU. The structure of the ONU optical component can be found in [reference needed]. Figure 2 Examples are not described here.

[0187] The ONU optical component can be integrated into the ONU; alternatively, the ONU optical component can be set up independently of the ONU and can be plugged into the ONU.

[0188] The OLT can connect to one or more ONU optical components via the ODN. There can be two or more ONU optical components. In this embodiment, the ONU optical component can be any one of the ONU optical components connected to the OLT.

[0189] An optical signal reception anomaly can refer to a situation where the OLT receives an optical signal emitted by the ONU optical component.

[0190] When an OLT receives an optical signal emitted by an ONU optical component, the optical signal reception anomaly may include at least one of the following situations: the OLT experiences a CRC error; the OLT's BER is greater than or equal to the BER threshold; or the OLT experiences packet loss.

[0191] Specifically, when the OLT receives the optical signal emitted by the ONU optical component, if the OLT has a CRC error, the OLT's BER is greater than the BER threshold, or the OLT experiences packet loss, the OLT can consider the optical signal reception to be abnormal.

[0192] For an explanation of the monitoring values ​​of the actual transmitted optical power of the ONU optical component, please refer to [link / reference needed]. Figure 2 Examples are not described here.

[0193] The optical signal can be the optical signal emitted by the ONU optical component to the OLT with the actual transmitted optical power, and arrives at the OLT receiver through the optical link.

[0194] The actual transmitted optical power of the ONU optical component can be the actual transmitted optical power of the LD in the ONU optical component at the current moment.

[0195] In this embodiment, the actual transmitted optical power of the ONU optical component can be measured by an optical power measurement device and stored in the ONU optical component. For example, the optical power measurement device can be an optical power meter.

[0196] In practice, the OLT can obtain the monitoring value of the actual transmitted optical power of the ONU optical component from the ONU optical component.

[0197] S402. Determine whether the monitored value is less than the upper limit of the emitted optical power of the ONU optical component.

[0198] The upper limit of the transmitted optical power of the ONU optical component can be any of the following: the specification upper limit of the monitored value of the transmitted optical power of the ONU optical component, or the theoretical maximum value of the monitored value of the transmitted optical power of the ONU optical component, etc.

[0199] It should be noted that the upper limit of the emitted optical power of the ONU optical component can be pre-stored in the OLT.

[0200] S403. If the monitored value is less than the upper limit of the transmitted optical power, send an indication message to the ONU optical component.

[0201] The instruction message is used to instruct the ONU optical component to adjust the actual transmitted optical power until the abnormal optical signal reception disappears.

[0202] Specifically, if the monitored value is less than the upper limit of the transmitted optical power, the OLT can instruct the ONU optical components to adjust the actual transmitted optical power.

[0203] It should be noted that if the actual transmitted optical power of the ONU optical component is low, the OLT will experience abnormal optical signal reception. In other words, abnormal optical signal reception in the OLT may be caused by the low actual transmitted optical power of the ONU optical component.

[0204] In one possible implementation, when an optical signal reception anomaly occurs, the OLT can directly send an indication message to the ONU optical component. Upon receiving the indication message, the ONU optical component can determine whether the monitored value is less than the upper limit of its transmit optical power. In this method, the upper limit of the ONU optical component's transmit optical power can be pre-stored. This approach eliminates the need for the OLT to obtain the actual transmit optical power monitoring value of the ONU optical component, thus reducing the OLT's overhead.

[0205] In the communication method provided in this embodiment, when optical signal reception is abnormal, the OLT can obtain a monitoring value of the actual transmitted optical power of the ONU optical component; it can determine whether the monitoring value is less than the upper limit of the transmitted optical power of the ONU optical component; if the monitoring value is less than the upper limit of the transmitted optical power, the OLT can send an indication message to the ONU optical component, which instructs the ONU optical component to adjust its actual transmitted optical power. Through this method, the actual transmitted optical power of the ONU optical component can be automatically adjusted when optical signal reception is abnormal, thus avoiding poor communication quality due to a low actual transmitted optical power of the ONU optical component and improving the communication quality between the ONU optical module and the OLT.

[0206] Based on any of the above embodiments, the following is combined with Figure 5 The method for the OLT to instruct the ONU optical component to adjust the actual luminous power is further explained.

[0207] Figure 5This is a flowchart illustrating another communication method provided in an embodiment of this application. The executing entity of this method can be an OLT (Optical Line Transport Unit) or a communication device located within the OLT. The communication device can be implemented through software or a combination of software and hardware. For ease of understanding, the following explanation uses an OLT as the executing entity. Please refer to... Figure 5 The method may include:

[0208] S501. When the optical signal reception is abnormal, obtain the monitoring value of the actual transmitted optical power of the ONU optical component.

[0209] S502. Determine whether the monitored value is less than the upper limit of the emitted optical power of the ONU optical component.

[0210] It should be noted that the specific implementation methods of S501-S502 can be found in S401-S402, and will not be repeated here.

[0211] S503. If the monitored value is less than the upper limit of the transmitted optical power, determine the optical power adjustment amount corresponding to the ONU optical component based on the monitored value and the upper limit of the transmitted optical power.

[0212] When determining the optical power adjustment amount corresponding to the ONU optical component, the OLT can determine the third difference between the upper limit of the transmitted optical power and the monitored value; the product of the third difference and the equal division coefficient is determined as the optical power adjustment amount.

[0213] The division factor can be a pre-set parameter used to indicate the proportion of the optical power adjustment in the third difference.

[0214] The division coefficient can be set according to actual needs, and this embodiment does not limit it.

[0215] Specifically, the optical power adjustment amount can be determined using the following formula:

[0216] Optical power adjustment amount = equal division coefficient * third difference,

[0217] The third difference is calculated as: upper limit of transmitted optical power - monitoring value.

[0218] For example, assuming the division factor is 0.2, the upper limit of the transmitted optical power is 4dBm, and the monitoring value is 2.8dBm, then the optical power adjustment amount = 0.2*(4dBm-2.8dBm) = 0.24dBm.

[0219] S504. Send indication information to the ONU optical component. The indication information includes the optical power adjustment amount and / or the target transmitted optical power, where the target transmitted optical power is the sum of the monitored value and the optical power adjustment amount.

[0220] Specifically, the instruction information exists in at least two of the following situations:

[0221] Case 1: The indication information includes the optical power adjustment amount.

[0222] In this case, the OLT can send an optical power adjustment amount to the ONU optical component. After receiving the optical power adjustment amount, the ONU optical component can determine the target transmit optical power by summing the monitored value and the optical power adjustment amount.

[0223] In this case, the OLT does not need to determine the target's transmitted optical power, resulting in lower OLT overhead.

[0224] Scenario 2: The indication information includes the target's emitted optical power.

[0225] In this case, the ONU optical component can directly obtain the target transmitted optical power from the OLT, resulting in lower overhead for the ONU optical component.

[0226] The communication method provided in this embodiment allows the OLT to acquire a monitoring value of the actual transmitted optical power of the ONU optical component when optical signal reception is abnormal. It can determine whether the monitoring value is less than the upper limit of the transmitted optical power of the ONU optical component. If the monitoring value is less than the upper limit, it can determine the corresponding optical power adjustment amount for the ONU optical component based on the monitoring value and the upper limit. It can also send an indication message to the ONU optical component, which includes the optical power adjustment amount and / or a target transmitted optical power, where the target transmitted optical power is the sum of the monitoring value and the optical power adjustment amount. In this way, the ONU optical component can automatically adjust its actual transmitted optical power according to the indication message. Through this method, the actual transmitted optical power of the ONU optical component can be automatically adjusted when optical signal reception is abnormal, thus avoiding poor communication quality due to a low actual transmitted optical power of the ONU optical component and improving the communication quality between the ONU optical module and the OLT.

[0227] Based on any of the above embodiments, the ONU optical component can adjust the actual transmitted optical power of the ONU optical component according to the instruction information of the OLT and the ONU optical component transmission index parameters stored in the ONU optical component, so as to eliminate the abnormal optical signal reception of the OLT.

[0228] The emission parameters of the ONU optical component can be parameters that are predetermined by measuring or calibrating the ONU optical component (such as index parameters or attribute parameters).

[0229] Based on any of the above embodiments, the following is combined with Figure 6 The method for determining the emission index parameters of the ONU optical component provided in the embodiments of this application is described.

[0230] Figure 6 This is a flowchart illustrating a method for determining the emission parameters of an ONU optical component, as provided in an embodiment of this application.

[0231] Please see Figure 6 The method may include:

[0232] S601. Determine the threshold current of the ONU optical component.

[0233] The threshold current is the bias current applied to the ONU optical component when the emitted optical power of the ONU optical component is at a preset emitted optical power.

[0234] The preset transmit optical power can be set according to actual needs, and this embodiment does not limit it. Optionally, the preset transmit optical power can be -40dBm.

[0235] In this embodiment, a bias current and a modulation current can be applied to the ONU optical component. The magnitude of the modulation current can be controlled to always be 0, the initial bias current can be controlled to be 0, and the bias current can be continuously increased at fixed intervals. Simultaneously, the emitted optical power of the ONU optical component under different bias currents can be measured until the emitted optical power of the ONU optical component reaches a preset emitted optical power. At this point, the bias current applied to the ONU optical component can be determined as the threshold current.

[0236] Below, taking a preset transmit optical power of -40dBm as an example, combined with... Figure 7 The threshold current is explained.

[0237] Figure 7 The transmitted optical power curve of another ONU optical component provided in this application embodiment is shown. Please refer to... Figure 7 The horizontal axis represents the bias current applied to the ONU optical component, and the vertical axis represents the emitted optical power of the ONU optical component.

[0238] like Figure 7 As shown, when the emitted optical power of the ONU optical component is -40dBm, the bias current applied to the ONU optical component can be Ith. That is, the threshold current can be Ith.

[0239] S602. Determine the first optical power and the second optical power based on the threshold current.

[0240] The first optical power is the actual emitted optical power of the ONU optical component under a preset bias current.

[0241] The second optical power is the actual emitted optical power of the ONU optical component under preset bias current and preset modulation current.

[0242] The preset bias current is the sum of the threshold current and the first preset value.

[0243] The first preset value and the preset modulation current can be set according to actual needs, and this embodiment does not limit them. Optionally, the first preset value can be 1mA, 1.5mA, or 2mA, etc., and the preset modulation current can be 25mA, 30mA, or 35mA, etc.

[0244] In this embodiment, a preset bias current can be determined based on a threshold current, and a first optical power and a second optical power can be determined based on the preset bias current and a preset modulation current.

[0245] It should be noted that the specific implementation methods for determining the first optical power and the second optical power can be found in [reference needed]. Figure 8 This will not be elaborated upon here.

[0246] S603. Determine the luminous efficiency based on the first optical power and the second optical power.

[0247] In this embodiment, a first difference between the second optical power and the first optical power can be determined; the ratio of the first difference to the preset modulation current is determined as the luminous efficiency of the ONU optical component.

[0248] Specifically, the luminous efficiency of the ONU optical component can be determined using the following formula:

[0249] ONU optical component luminous efficiency = (second optical power - first optical power) / preset modulation current

[0250] In this embodiment, the emission performance parameters include one or more of the following: threshold current of the ONU optical component, first optical power, second optical power, or luminous efficiency.

[0251] The method for determining the emission parameters of the ONU optical component provided in this embodiment can determine the threshold current of the ONU optical component; determine the first optical power and the second optical power based on the threshold current; and determine the luminous efficiency based on the first optical power and the second optical power. Through the above method, the emission parameters of the ONU optical component can be determined, so that the actual emitted optical power of the ONU optical component can be adjusted according to the emission parameters.

[0252] exist Figure 6 Based on the embodiments, the following is combined with Figure 8 The method for determining the emission parameters of the ONU optical component is further explained.

[0253] Figure 8 This is a flowchart illustrating another method for determining the emission parameters of an ONU optical component, provided in an embodiment of this application. Please refer to... Figure 8 The method may include:

[0254] S801, Apply the i-th bias current to the ONU optical component.

[0255] The i-th bias current is i * current step size, where i takes the values ​​1, 2, ..., i is a positive integer.

[0256] The current step size can be set according to actual needs, and this embodiment does not limit it. Optionally, the current step size can be 0.2mA, 0.1mA, or 0.15mA, etc.

[0257] S802. Obtain the i-th actual transmitted optical power of the ONU optical component at the i-th bias current, until the i-th actual transmitted optical power is equal to the preset transmitted optical power, and then determine the i-th bias current as the threshold current.

[0258] In this embodiment, the actual transmitted optical power of the ONU optical component under the i-th bias current can be obtained sequentially until the i-th actual transmitted optical power is equal to the preset transmitted optical power, at which point the i-th bias current can be determined as the threshold current. Here, i takes the values ​​1, 2, ... sequentially.

[0259] S803. Apply a preset bias current to the ONU optical component and determine the actual emitted optical power of the ONU optical component under the preset bias current as the first optical power.

[0260] In this embodiment, by applying a preset bias current to the ONU optical component, the actual emitted optical power of the ONU optical component under the preset bias current can be obtained, and the actual emitted optical power of the ONU optical component under the preset bias current can be determined as the first optical power.

[0261] It should be noted that when determining the first optical power, only a preset bias current needs to be applied to the ONU optical component, and no modulation current needs to be applied to the ONU optical component (that is, the magnitude of the modulation current applied to the ONU optical component is 0).

[0262] In practice, at least the following two methods can be used to achieve the goal of applying a modulation current of 0 to the ONU optical component:

[0263] Method 1: Do not apply modulation current to the ONU optical component;

[0264] Method 2: Apply a modulation current to the OUN optical component (the magnitude of the modulation current can be arbitrary) and simultaneously send a low-level signal (i.e., a level signal with code "0") to the ONU optical component.

[0265] It should be noted that low-level information can be sent to the OUN optical component through a signal code transmission device.

[0266] S804. Apply a preset bias current and a preset modulation current to the ONU optical component, and determine the actual emitted optical power of the ONU optical component under the preset bias current and the preset modulation current as the second optical power.

[0267] In this embodiment, a preset bias current and a preset modulation current can be applied to the ONU optical component to obtain the actual transmitted optical power of the ONU optical component under the preset bias current and preset modulation current, and the actual transmitted optical power of the ONU optical component under the preset bias current and preset modulation current can be determined as the second optical power.

[0268] It should be noted that when determining the second optical power, a preset bias current and a preset modulation current must be applied to the ONU optical component simultaneously.

[0269] When applying a preset modulation current to the ONU optical component, it is necessary to simultaneously send a high-level signal (i.e., a level signal with code "1") to the ONU optical component. In this way, the purpose of applying the preset modulation current to the ONU optical component can be achieved.

[0270] For example, assuming the preset bias current is 15mA and the preset modulation current is 25mA, when the second optical power is determined, a bias current of 15mA and a modulation current of 25mA need to be applied to the ONU optical component, and a high-level signal needs to be sent to the ONU optical component at the same time.

[0271] For example, assuming the preset bias current is 16mA and the preset modulation current is 25mA, when the second optical power is determined, a bias current of 16mA and a modulation current of 25mA need to be applied to the ONU optical component, and a high-level signal needs to be sent to the ONU optical component at the same time.

[0272] It should be noted that different signal codes can be sent to the OUN optical component via a signal code transmission device.

[0273] Below, in conjunction with Figure 9 The first optical power and the second optical power will be explained.

[0274] Figure 9 This is a graph showing the transmitted optical power of another ONU optical module provided in an embodiment of this application. Please refer to [link / reference]. Figure 9 The horizontal axis represents the current applied to the ONU optical component, and the vertical axis represents the emitted optical power of the ONU optical component.

[0275] like Figure 9 As shown, when a preset bias current is applied to the ONU optical component, the emitted optical power of the ONU optical component can be a first optical power. When both a preset bias current and a preset modulation current are applied to the ONU optical component, the emitted optical power of the ONU optical component can be a second optical power.

[0276] S805. Determine the luminous efficiency based on the first optical power and the second optical power.

[0277] It should be noted that the specific implementation of S805 can be found in S603, and will not be repeated here.

[0278] In the method for determining the emission parameters of the ONU optical component provided in this embodiment, an i-th bias current can be applied to the ONU optical component; the i-th actual emitted optical power of the ONU optical component under the i-th bias current can be obtained until the i-th actual emitted optical power is a preset emitted optical power, at which point the i-th bias current is determined as a threshold current; a preset bias current can be applied to the ONU optical component, and the actual emitted optical power of the ONU optical component under the preset bias current is determined as a first optical power; a preset bias current and a preset modulation current can be applied to the ONU optical component, and the actual emitted optical power of the ONU optical component under the preset bias current and the preset modulation current is determined as a second optical power; and the luminous efficiency can be determined based on the first optical power and the second optical power. Through the above method, the emission parameters of the ONU optical component can be determined, so that the actual emitted optical power of the ONU optical component can be adjusted according to the emission parameters.

[0279] Based on any of the above embodiments, this application also provides a system for determining the emission parameters of an ONU optical component. The system may include a testing component and a control device. Further, the testing component may include a test board and a measurement device. Below, in conjunction with... Figure 10 This paper describes the system for determining the emission parameters of the ONU optical component.

[0280] Figure 10 This is a schematic diagram of a system for determining the emission parameters of an ONU optical component, provided in an embodiment of this application. Please refer to... Figure 10 The system for determining the emission parameters of an ONU optical component can include a test board, measurement equipment, and control equipment.

[0281] The test board can be connected to both control and measurement devices.

[0282] The test board can be used to insert ONU optical components.

[0283] The control device can be used to control the magnitude of the current applied to the ONU optical component.

[0284] The measuring equipment can be used to measure the emitted optical power of the ONU optical component.

[0285] It should be noted that the emitted optical power of the ONU optical component measured by the measuring equipment can be the actual emitted optical power of the ONU optical component.

[0286] It should be noted that, Figure 10The description of the structure of the ONU optical component emission parameter determination system is merely illustrative and does not constitute a limitation on the ONU optical component emission parameter determination system. The ONU optical component emission parameter determination system may also include more or fewer components than those shown in the figure.

[0287] For example, the ONU optical component emission parameter determination system may also include a power supply, which can be used to provide current to the ONU optical component on the test board.

[0288] For example, the ONU optical component emission parameter determination system may also include a signal pattern transmission device, which can be connected to the test board and used to send modulation level signals to the ONU optical component on the test board.

[0289] Based on any of the above embodiments, this application also provides a method for determining the emission index parameters of an ONU optical component. Below, in conjunction with... Figure 11 The method for determining the emission parameters of the ONU optical component is further explained.

[0290] Figure 11 This is a flowchart illustrating another method for determining the emission parameters of an ONU optical component, provided in an embodiment of this application. Please refer to... Figure 11 The method may include:

[0291] S1101, The control device applies the i-th bias current to the ONU optical component through the test board.

[0292] It should be noted that the specific details of the i-th bias current can be found in S801, and will not be repeated here.

[0293] S1102. The control device obtains the i-th actual transmitted optical power of the ONU optical component at the i-th bias current through the measuring device, and determines the i-th bias current as the threshold current when the i-th actual transmitted optical power is the preset transmitted optical power.

[0294] In this embodiment, the control device can sequentially obtain the i-th actual transmitted optical power of the ONU optical component under the i-th bias current through the measuring device, until the i-th actual transmitted optical power is the preset transmitted optical power. At this point, the control device can determine the i-th bias current as the threshold current. Here, i takes the values ​​1, 2, ... sequentially.

[0297] It should be noted that the method for applying a preset bias current to the ONU optical component can be found in S803, and will not be repeated here.

[0298] S1104. The control device applies a preset bias current and a preset modulation current to the ONU optical component through the test board, and determines the actual emitted optical power of the ONU optical component under the preset bias current and the preset modulation current as the second optical power.

[0303] Based on any of the above embodiments, the following, in conjunction with Figure 12 This paper explains the method for adjusting the actual transmitted optical power of the ONU optical component based on the indication information and the transmission index parameters of the ONU optical component.

[0304] Figure 12 This is a flowchart illustrating another communication method provided in an embodiment of this application. The executing entity of this method can be an ONU optical component or a communication device disposed within the ONU optical component.

[0310] It should be noted that the specific method for determining the target modulation current based on the target's emitted optical power can be found in [reference needed]. Figure 13 Examples are not detailed here.

[0311] S1203. Apply the target modulation current to the ONU optical component.

[0312] The communication method provided in this embodiment allows the ONU optical component to receive indication information sent by the OLT; determine the target modulation current based on the indication information and the ONU optical component's transmission parameters; and apply the target modulation current to the ONU optical component to adjust its actual transmitted optical power to the target transmitted optical power. Through this method, the ONU optical component can automatically adjust its actual transmitted optical power according to the OLT's indication information, thus avoiding poor communication quality due to low actual transmitted optical power and improving the communication quality between the ONU optical module and the OLT.

[0313] Based on any of the above embodiments, the following, in conjunction with Figure 13 The method for determining the target modulation current of the ONU optical component based on the target emitted optical power is explained.

[0314] Figure 13 This is a flowchart illustrating another communication method provided in an embodiment of this application. The executing entity of this method can be an ONU optical component or a communication device disposed within the ONU optical component. The communication device can be implemented through software or a combination of software and hardware. For ease of understanding, the following explanation will use an ONU optical component as the executing entity. Please refer to... Figure 13 The method may include:

[0315] S1301, Receive the instruction information sent by the OLT.

[0316] The instruction information is used to instruct the ONU optical component to adjust the actual emitted optical power.

[0317] The indication information may include the optical power adjustment amount or the target emitted optical power.

[0318] S1302. Determine the target's emitted optical power based on the indicated information.

[0319] In this embodiment, if the indication information includes an optical power adjustment amount, the ONU optical component can determine the target transmitted optical power by summing the monitored value and the optical power adjustment amount. If the indication information includes a target transmitted optical power, the ONU optical component can determine the target transmitted optical power in the indication information as the target transmitted optical power.

[0320] S1303. Determine the target modulation current based on the target transmitted optical power and the transmission parameters of the ONU optical component.

[0321] In this embodiment, the ONU optical component can receive the ONU optical component transmission index parameters sent by the control device in advance, and can store the ONU optical component transmission index parameters in the ONU optical component. Furthermore, the ONU optical component can store the ONU optical component transmission index parameters in its storage unit.

[0322] The control equipment can be any control device included in the ONU optical component emission parameter determination system. Optionally, the control equipment can be a server or a computer, etc.

[0323] Before determining the target modulation current based on the target transmitted optical power and the transmission parameters of the ONU optical component, the ONU optical component can obtain the transmission parameters of the ONU optical component from its storage unit.

[0324] The emission parameters of the ONU optical component may include one or more of the following: threshold current, luminous efficiency, first optical power or second optical power of the ONU optical component.

[0325] In one possible implementation, the emission parameters of the ONU optical component may include a first optical power and luminous efficiency. In this approach, the ONU optical component can determine the target modulation current in the following manner:

[0326] The ONU optical module can determine the second difference between the third optical power and the first optical power; the ratio of the second difference to the luminous efficiency is determined as the target modulation current.

[0327] The target emitted optical power is the average of the third optical power and the first optical power. That is, the third optical power = 2 * target emitted optical power - first optical power.

[0328] Second difference = 2 * target emitted optical power - first optical power - first optical power = 2 * (target emitted optical power - first optical power)

[0329] Specifically, the target modulation current can be determined using the following formula:

[0330]

[0331] In this method, the target modulation current can be determined directly based on the ONU optical component's emission index parameters and the target emitted optical power, resulting in a lower overhead for the ONU optical component.

[0332] In another possible implementation, the emission parameters of the ONU optical component can include a threshold current. The ONU optical component can determine a preset bias current based on the threshold current.

[0333] In this method, the ONU optical component can also store a preset modulation current.

[0334] In this method, when determining the target modulation current, the ONU optical component can obtain the actual emitted optical power (i.e., the first optical power) of the ONU optical component under the preset bias current through an external measuring device, and can obtain the actual emitted optical power (i.e., the second optical power) of the ONU optical component under the preset bias current and the preset modulation current through a measuring device, and can determine the luminous efficiency of the ONU optical component based on the first optical power, the second optical power and the preset modulation current.

[0335] In this method, after the ONU optical component determines the first optical power and luminous efficiency, the target modulation current can be determined based on the first optical power, luminous efficiency and target emitted optical power.

[0336] In this method, the ONU optical component needs to store fewer parameters, thus saving storage resources for the ONU optical component.

[0337] In another possible implementation, the emission parameters of the ONU optical component can include threshold current and luminous efficiency. The ONU optical component can determine the preset bias current based on the threshold current.

[0338] In this method, when determining the target modulation current, the ONU optical component can obtain the actual emitted optical power (i.e., the first optical power) of the ONU optical component under a preset bias current through an external measuring device, and can determine the target modulation current based on the target emitted optical power, the first optical power, and the luminous efficiency.

[0339] In this method, the ONU optical component does not need to determine the second optical power, which reduces the overhead of the ONU optical component.

[0340] S1304. Apply the target modulation current to the ONU optical component.

[0341] In the communication method provided in this embodiment, the ONU optical component can receive indication information sent by the OLT, determine the target transmit optical power based on the indication information, determine the target modulation current based on the target transmit optical power and the transmit parameter parameters of the ONU optical component, and apply the target modulation current to the ONU optical component. Through this method, the ONU optical component can automatically adjust its actual transmit optical power according to the indication information from the OLT, thereby avoiding situations where the actual transmit optical power of the ONU optical component is too low, leading to poor communication quality and improving the communication quality between the ONU optical module and the OLT.
