[0002] With the development of optical access communication technology, a three-generation coexistence mechanism for 50G-PON in EPON areas has emerged, divided into wavelength division coexistence and time division coexistence. Besides the differences in uplink technology, the core difference in the downlink is that the 50G-PON channels in the two schemes use different wavelengths. In actual operation and maintenance, installation engineers need to carry different types of ONU optical modules and know in advance which wavelength the corresponding PON port at the optical line terminal (OLT) uses in order to install the corresponding terminal. Therefore, this installation method not only affects installation efficiency but also adds identification steps to subsequent fault handling, increasing complexity.

[0058] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0059] The optical module control method provided in this application embodiment can be applied to, for example... Figure 1 In the application environment shown, terminal 102 communicates with server 104 via a network. A data storage system can store the data that server 104 needs to process. The data storage system can be integrated onto server 104 or placed in the cloud or on other network servers. Server 104 receives optical signals; performs photoelectric conversion on the optical signals to obtain electrical signals; compensates the electrical signals according to the digital signal processing submodule to obtain compensated electrical signals; performs frame parsing on the compensated electrical signals to obtain wavelength data; and adaptively adjusts the signal processing algorithm of the digital signal processing submodule according to the wavelength data. Terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can be smart speakers, smart TVs, smart air conditioners, smart in-vehicle devices, projection devices, etc. Portable wearable devices can be smartwatches, smart bracelets, head-mounted devices, etc. Head-mounted devices can be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc. Server 104 can be a standalone physical server, a server cluster or distributed system consisting of multiple physical servers, or a cloud server that provides cloud computing services.

[0060] In one exemplary embodiment, such as Figure 2 As shown, an optical module control method is provided, which is applied to... Figure 1 Taking server 104 as an example, the explanation includes the following steps 202 to 210. Wherein:

[0061] Step 202: Receive optical signal.

[0062] The optical signal can be distributed and transmitted by the optical distribution network (ODN). In a specific 50G-PON channel, the optical signal can use different wavelengths, such as 1286±2nm, 1342±2nm, or 1366±2nm.

[0063] In some embodiments, the optical signal can be received by receiving the optical signal allocated by the optical distribution network (ODN) through the receiving side of the photoelectric conversion module, or the optical signal can be received in other ways, not limited to these.

[0064] Step 204: Perform photoelectric conversion processing on the optical signal to obtain an electrical signal.

[0065] The photoelectric conversion processing includes the processing of optical signals, as well as the conversion and output processing of the processed optical signals.

[0066] In some embodiments, photoelectric conversion processing of the optical signal to obtain an electrical signal includes: performing dual-channel filtering processing on the optical signal according to a dual-channel wavelength filter to obtain a downlink wavelength signal; and performing photoelectric conversion on the downlink wavelength signal according to an optical receiver and a transimpedance amplifier to obtain an electrical signal.

[0067] In some embodiments, in the optical signal processing section on the receiving side, a pre-dual-channel wavelength filter is used to perform dual-channel filtering processing on the optical signal, so that both 1366±2nm and 1342±2nm wavelength signals can be passed through the filter to obtain a downlink wavelength signal containing both wavelength signals.

[0068] In some embodiments, the downlink wavelength signal is photoelectrically converted by the optical receiver and transimpedance amplifier to output an electrical signal with a 1342±2nm channel or an electrical signal with a 1366±2nm channel, resulting in two electrical signals. Therefore, by using a pre-amplified dual-channel wavelength filter to achieve photoelectric signal conversion, it is possible to accurately perform photoelectric conversion processing on specific wavelength signals, while simultaneously solving the input problem of the optical module through dual-channel filtering.

[0069] It should be noted that a dual-channel wavelength filter can be a broadband wavelength filter that includes the two passbands of the aforementioned dual-channel wavelength filter. The function of this broadband wavelength filter is similar to that of a dual-channel wavelength filter. If the passbands of the two channels of this broadband wavelength filter are closely adjacent or have an overlap, it is a special implementation of a dual-channel wavelength filter.

[0070] Step 206: The electrical signal is compensated according to the digital signal processing submodule to obtain the compensated electrical signal.

[0071] Among them, the electrical signal compensation based on the digital signal processing submodule aims to reverse the damage to the electrical signal acquired at the front end in the digital domain through pure software or hardware-software collaboration. The signal is processed in reverse by the DSP algorithm model of the digital signal processing submodule, thereby achieving the compensation effect to offset the damage effect.

[0072] In some embodiments, the DSP algorithm used by the digital signal processing submodule for electrical signal compensation can be specifically implemented through one or more of the following algorithms: noise and interference suppression based on adaptive filtering theory, mainly used to eliminate incoherent additive noise and periodic interference in the signal, such as LMS or RLS algorithms; nonlinear distortion correction based on Volterra series and memory polynomials, mainly used for mild nonlinearity and no memory effect, and a simple memoryless polynomial model can be used.

[0073] In this embodiment, by flexibly applying various DSP algorithms of the aforementioned digital signal processing submodule to compensate for the electrical signal, a compensated electrical signal is obtained. The system can address almost all modelable damages in the signal link with extremely high accuracy and flexibility, and finally output a pure, linear, and high-fidelity compensated electrical signal.

[0074] Step 208: Perform frame parsing on the compensation electrical signal to obtain wavelength data.

[0075] Frame resolution refers to identifying wavelengths using downlink TC frame indicator bits.

[0076] In some embodiments, performing frame parsing on the compensated electrical signal to obtain wavelength data includes: performing frame parsing on the electrical signal to obtain downlink frame data; and obtaining wavelength data based on the target field of the downlink frame data.

[0077] In some embodiments, the ONU optical module receives the compensation electrical signal and parses the downlink frame data (TC frame) of the compensation electrical signal transmitted by the OLT downlink, and obtains the wavelength data used for downlink from the target field (DWLCH ID field) in the TC frame.

[0078] In some embodiments, after obtaining wavelength data through frame parsing, the TC layer notifies the DSP chip of the wavelength data used for downlink wavelength. Based on the identified wavelength data, the TC chip in the TC layer transmits it to the DSP chip through the electrical interface between the TC chip and the optical module. The DSP chip is a digital signal processing submodule in the optical module.

[0079] In some embodiments, the ONU TC chip receives the compensation electrical signal processed by the DSP, parses it to obtain the TC frame, and extracts the DWLCH ID field value in the PON-ID field from the TC frame. When the value is 0x1000, it indicates a wavelength channel of 1342±2nm.

[0080] In some embodiments, the ONU TC chip receives the compensation electrical signal processed by the DSP, parses it to obtain the TC frame, and extracts the DWLCH ID field value in the PON-ID field from the TC frame. When the value is 0x1001, it indicates a wavelength channel of 1366±2nm.

[0081] Step 210: Adaptively adjust the signal processing algorithm of the digital signal processing submodule based on the wavelength data.

[0082] Adjusting the candidate digital signal processing submodule refers to adjusting the algorithm model within the candidate digital signal processing submodule.

[0083] In some embodiments, adaptively adjusting the signal processing algorithm of the digital signal processing submodule based on wavelength data includes: determining a target signal processing algorithm based on wavelength data; and replacing the signal processing algorithm based on the target signal processing algorithm.

[0084] In some embodiments, wavelength data transmitted by the MCU is received, a target DSP signal processing algorithm for switching is determined based on the wavelength data, and the signal processing algorithm is replaced according to the target signal processing algorithm to switch the signal processing algorithm of the digital signal processing submodule to the corresponding target DSP signal processing algorithm.

[0085] In some embodiments, adaptively adjusting the signal processing algorithm of the digital signal processing submodule based on wavelength data includes: determining adjustment parameters of the signal processing algorithm based on wavelength data; and adjusting the parameters of the signal processing algorithm based on the adjustment parameters to adapt to the corresponding wavelength data.

[0086] In some embodiments, wavelength data transmitted by the MCU is received, adjustment parameters for the DSP signal processing algorithm used for switching are determined based on the wavelength data, and model parameters of the signal processing algorithm are adjusted according to the adjustment parameters to adjust the corresponding parameters of the DSP signal processing algorithm of the digital signal processing submodule to adapt to the corresponding wavelength data.

[0087] In some embodiments, the method further includes: acquiring multiple optical signals; performing wavelength division processing on the multiple optical signals to obtain a downlink wavelength division signal; acquiring setting data of an optical switch according to the coexistence area type where the optical module is located; and setting the setting data optical switch according to the setting data so that the setting data optical switch outputs the optical signal corresponding to the setting data from the downlink wavelength division signal of the setting data.

[0088] Among them, multi-channel optical signals are formed by combining multiple optical signals of different wavelengths through a multiplexer. Wavelength division processing refers to the process of dividing multi-channel optical signals through a multiplexer. At the receiving end of the optical module, the different wavelengths in the multi-channel optical signals are separated by the wavelength divisioner and sent to the corresponding optical receivers (such as ONU, OLT and other devices) to restore the original optical signals.

[0089] It should be noted that the coexistence area type of the optical module can refer to a time-division coexistence area or a wavelength-division coexistence area. The time-division coexistence area solves the wavelength conflict problem of multiple generations of PON systems through time-division multiplexing and hybrid DBA scheduling, enabling the optical module function to smoothly upgrade the network from low speed to high speed. The wavelength-division coexistence area solves the wavelength conflict problem of multiple generations of PON systems through technologies such as narrowband EPON, multimode optical modules, and miniaturized trimode optical modules, enabling the optical module function to smoothly upgrade the network from low speed to high speed.

[0090] In some embodiments, multiple optical signals transmitted by the ODN device can be acquired by a multiplexer / demultiplexer, and the multiple optical signals can be demultiplexed by the multiplexer to obtain two downlink demultiplexed signals and an uplink demultiplexed signal with different wavelengths. The two downlink demultiplexed signals with different wavelengths are input to the optical switch on the ONU device. The optical switch determines the setting data of the optical switch according to the coexistence area type where the optical module is located, while the uplink demultiplexed signal is processed by the uplink optical path processing module.

[0091] In some embodiments, such as Figure 3 As shown, Figure 3 This document illustrates the processing flowchart of multiple optical signals after input to the ONU optical module. Based on the coexistence region type of the optical module, selection is triggered by a hardware switch on the ONU device to obtain the optical switch's setting data. The optical switch is then configured according to this data, causing it to output the corresponding optical signal from the downlink wavelength division multiplexing (WDM) signal. Specifically, in a time-division multiplexing region, the optical switch can be configured to output a 1366±2 nm branch, resulting in an optical signal with a wavelength of 1366±2 nm; in a wavelength-division multiplexing region, it can be configured to output a 1342±2 nm branch, also resulting in an optical signal with a wavelength of 1342±2 nm, and so on.

[0092] In the aforementioned optical module control method, an optical signal is received; the optical signal undergoes photoelectric conversion to obtain an electrical signal; the electrical signal is compensated by a digital signal processing submodule to obtain a compensated electrical signal; the compensated electrical signal undergoes frame parsing to obtain wavelength data; and the signal processing algorithm of the digital signal processing submodule is adaptively adjusted based on the wavelength data. Therefore, by receiving an optical signal, performing photoelectric conversion to obtain an electrical signal, then compensating the electrical signal according to a digital signal processing submodule to obtain a compensated electrical signal, performing frame parsing on the compensated electrical signal to obtain wavelength data, and then adaptively adjusting the signal processing algorithm of the digital signal processing submodule based on the wavelength data, the method can solve the problem of normalization in 50G-PON ONU optical modules through the internal technical optimization of the joint working mechanism of the optical module and the TC layer chip of the data transmission layer. This effectively reduces the types of optical module terminals and lowers the complexity of inventory preparation and installation / maintenance by existing network maintenance engineers.

[0093] In some embodiments, to better understand the solution of this application, the following are combined with Figure 4 , Figure 5 , Figure 6 and Figure 7 The explanation is as follows:

[0094] In some embodiments, such as Figure 4 As shown, Figure 4 This diagram illustrates the interactions between the various sub-modules within an optical module of this solution, as well as the flow chart between the optical module and the TC layer. The numbered sections are used to label specific interaction steps, as shown in the diagram. Figure 4 As shown, a dual-channel filtering method is used: In the optical signal processing section on the receiving side, a pre-filtering function is used to introduce the two wavelength signals of 1366±2nm and 1342±2nm from step ① into the corresponding APD receiver in the photoelectric conversion submodule. Then, through the transimpedance amplifier, the electrical signal of the 1342±2nm channel or the electrical signal of the 1366±2nm channel is output. Then, the DSP digital signal processing submodule sends the electrical signal to the TC layer to execute step ②, so as to obtain the wavelength data by parsing the downlink frame indicator bit of the electrical signal and provide the DSP digital signal processing submodule with a signal. The subsequent step ③ is that the TC layer notifies the DSP chip, i.e. the digital signal processing submodule, of the wavelength data used for the downlink wavelength. Finally, step ④ is that the 50G-PON DSP adjusts the DSP algorithm, specifically by switching the DSP algorithm according to the wavelength data, thereby improving the compensation performance, and then outputting it to the TC chip.

[0095] In some embodiments, the OLT side adopts an EPON third-generation wavelength division multiplexing scheme, with a downlink wavelength of 1342±2nm, such as Figure 5As shown, in the photoelectric conversion process, this technical solution employs a pre-filtering dual-channel function. When a wavelength of 1342±2nm passes through... Figure 6 The dual-channel filter shown enters the DSP module. Both the 1366±2nm and 1342±2nm wavelength channels can pass through this filter into the APD receiver, and then are output through a transimpedance amplifier. Specifically, as shown... Figure 7 As shown, Figure 7 This demonstrates how the ONU TC chip receives electrical signals processed by the DSP, parses them to obtain downlink TC frames, and extracts the DWLCH ID field value (0x1000) from the PON-ID field of the downlink TC frame. 0x1000 indicates a 1342±2nm wavelength channel. The TC chip transmits this downlink wavelength information (1342nm channel) to the DSP chip via the electrical interface with the optical module. Based on the wavelength information transmitted from the TC chip, the 50G-PON DSP module switches to the DSP algorithm corresponding to the 1342nm wavelength or adjusts the relevant parameters. Therefore, through the joint working mechanism of the optical module and the TC layer, the problem of 50G-PON ONU normalization is solved under the differentiated conditions of EPON third-generation coexistence time-division and wavelength-division coexistence schemes. This effectively reduces the number of ONU types, lowers inventory levels, and reduces the complexity of installation and maintenance for existing network operation and maintenance engineers.
