Description

Technical Field

[0002] With the rapid development of optical communication technology, optical modules, as the core component of optical transmission systems, play a crucial role in improving the stability and reliability of the entire communication system. However, with the rapid increase in optical module transmission rates, traditional CDR (Clock and Data Recovery) solutions are no longer sufficient to meet the performance requirements of optical modules. Therefore, DSP (Digital Signal Processing) technology has emerged and is now widely used in optical modules.

[0003] However, in practical applications, especially in telecom-grade applications, optical modules face numerous challenges. Increased transmission distances (e.g., 10km-40km) often lead to more fiber optic connectors, increased dispersion, and consequently, degraded signal quality. Furthermore, interference factors such as MPI (Multi-Path Interference) frequently affect signal quality. Therefore, if the DSP's response to signal fluctuations is too sensitive, brief or occasional signal degradation may cause frequent loss of lock and relocking of the optical signal, resulting in intermittent optical module outages. Conversely, if the DSP's response to signal fluctuations is too insensitive, the optical module may be locked into a suboptimal signal state, affecting communication stability and reliability. Therefore, ensuring that the optical module operates under optimal signal conditions while reducing the frequency of intermittent outages caused by signal fluctuations is a pressing issue that needs to be addressed.

[0020] Figure 1 This is a schematic diagram of the steps of an optical module locking control method according to an embodiment of the present invention.

[0021] Figure 2 This is a schematic diagram of some steps of the optical module locking control method in one embodiment of the present invention.

[0022] Figure 3 This is a schematic diagram of step S2 in one embodiment of the present invention.

[0023] Figure 4 This is a flowchart illustrating a preferred embodiment of the optical module locking control method in one embodiment of the present invention. Detailed Implementation

[0024] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0025] It should be noted that the term "comprising" or any other variation thereof is 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 process, method, article, or apparatus. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] like Figure 1 As shown, one embodiment of the present invention provides an optical module locking control method.

[0027] This optical module locking control method is applied to an optical module. The optical module locking control method includes the following steps.

[0028] Step S1: Obtain the locking conditions of the optical module; wherein, the locking conditions are the conditions that the optical signal must satisfy when locking the optical signal received by the optical module; the locking conditions include a first setting condition and a second setting condition, wherein the second setting condition has a lower optical signal quality standard than the first setting condition;

[0029] Step S2: The optical module receives the optical signal, locks the optical signal when the optical signal meets the first set condition, and updates the locking condition to the second set condition.

[0030] Step S3: When the optical signal meets the second set condition, keep the optical signal locked and process the optical signal.

[0031] Thus, by locking the optical signal when it meets the first set condition, the optical module can stably transmit high-quality optical signals, laying the foundation for subsequent signal processing and data transmission. While locking the optical signal, the locking condition of the optical module is updated so that the optical module can maintain the locked state of the optical signal even when the optical signal quality deteriorates. This effectively reduces the frequency of optical module outages caused by signal quality degradation. The optical module can better adapt to optical signals of different qualities, improving its robustness, stability, and reliability in the communication process, and enhancing the user experience and satisfaction.

[0032] In this context, "locking" refers to the optical module receiving an optical signal and determining whether the received signal meets the requirements. If so, the optical module performs subsequent processing on the received optical signal. Therefore, the purpose of signal locking by the optical module is to facilitate subsequent signal processing, such as converting the optical signal into an electrical signal and outputting it to a subsequent processing unit or device.

[0033] Specifically, when the optical module receives an optical signal, it determines whether the frequency of the received optical signal matches the preset frequency. If the frequency matches, the optical module detects and determines whether the quality of the optical signal meets the requirements. If the signal quality meets the requirements, the optical module adjusts its internal processing parameters according to the received optical signal to optimize the signal transmission and processing effect. Then, it converts the received optical signal into an electrical signal for output.

[0034] In one embodiment, locking the optical signal in step S2 includes locking the optical signal received by the optical module. In this embodiment, the locked optical signal is the original optical signal, and the locking operation is performed at the optical level.

[0035] In one embodiment, locking the optical signal in step S2 includes locking the electrical signal converted from the optical signal received by the optical module. In this embodiment, the optical module first converts the received optical signal into an electrical signal, and then locks the electrical signal; the locking operation is performed at the electrical level.

[0036] To correct signal distortion and noise during transmission, the optical module can adjust its internal processing parameters based on the received optical signal. These processing parameters can be configured to compensate for the signal and improve signal quality.

[0037] like Figure 2 As shown, in one embodiment, after locking the optical signal when the optical signal meets the first set condition, the method further includes the following steps.

[0038] Step M1: Perform signal compensation operation on the optical signal under the first set conditions to determine the signal compensation parameters;

[0039] Based on this, step S2 specifically includes the following steps.

[0040] Step M2: Under the second set conditions, perform signal compensation operation on the optical signal using the compensation parameters, and process the compensated signal.

[0041] Thus, by directly applying the compensation parameters determined under the first setting condition (with a higher signal quality standard) to the optical signal compensation operation under the second setting condition (with a lower signal quality standard), the signal distortion and noise under the second setting condition can be partially corrected, thereby improving the signal quality.

[0042] It should be noted that the optical signal in step M1 is the original optical signal, and the compensation operation on the optical signal is not limited to compensating the original optical signal.

[0043] In one embodiment, the optical module performs signal compensation operation on the received optical signal.

[0044] In one embodiment, a signal compensation operation is performed on the electrical signal converted from the optical signal received by the optical module.

[0045] Step M2, processing the compensated signal, can be either optical or electrical signal processing. When the optical module compensates for an optical signal, the signal processing refers to optical signal processing; when the optical module compensates for an electrical signal, the signal processing refers to electrical signal processing. The processing of the compensated signal specifically includes, but is not limited to, transmitting the signal to the server, signal conversion, data recovery, and decoding operations.

[0046] Before the optical module locks onto the signal, a relatively high signal quality is set (the first setting condition). This is to ensure that the optical module locks onto a high-quality, or even optimal, optical signal from the beginning, thereby ensuring the reliability of data transmission; and to provide a stable benchmark for subsequent signal quality adjustments, thereby improving the adaptability and fault tolerance of the optical module while ensuring basic communication quality.

[0047] The first setting condition should not be set too high, because the optical module may need to spend more time locking onto a signal that meets the first setting condition, resulting in an excessively long communication establishment time, or even the inability to find a signal that meets the condition. Similarly, the first setting condition should not be set too low, because the optical module may lock onto a signal of poor quality, resulting in a decrease in the accuracy and reliability of data transmission.

[0048] In one embodiment, the first setting condition can be determined based on a series of tests and statistical test results to ensure that the first setting condition is objective and effective and does not depend on personal subjective judgment.

[0049] For example, if the first setting condition is set to a signal-to-noise ratio greater than or equal to 17dB, and statistical test results show that the bit error rate remains unchanged or falls within the preset value range after the optical module is locked under a signal-to-noise ratio of 17dB or higher, then the first setting condition can be considered reasonable.

[0050] In actual communication, the quality of optical signals can be affected by various factors, such as noise and interference. If the optical module always requires the signal to meet a high quality standard (e.g., the first set condition), then even a slight fluctuation in signal quality may cause the optical module to lose its lock, leading to communication interruption. Therefore, setting a second set condition allows the optical module to maintain signal lock even when the signal quality deteriorates but remains acceptable, thereby enhancing the adaptability of the optical module.

[0051] The first set of conditions specifies the ideal quality conditions of the optical signal when the optical module communicates. Under this quality requirement, the optical module can achieve stable communication with a low bit error rate.

[0052] The second setting condition specifies the minimum quality requirement for the optical signal during optical module communication. Under this quality requirement, the optical module has a slightly higher bit error rate during communication but can still maintain communication.

[0053] In one embodiment, the optical module loses its lock when the quality of the optical signal does not meet the second set condition.

[0054] In one embodiment, the optical module remains locked when the quality of the optical signal meets the second preset condition.

[0055] Thus, by setting a lower signal quality standard (second setting condition), the optical module can maintain a locked state even when the signal quality deteriorates but remains within an acceptable range, thereby reducing unnecessary unlocking and relocking operations and effectively preventing flicker; at the same time, it can also maintain the optical module's effective control over signal unlocking and locking.

[0056] Compared to the first setting condition, the second setting condition has lower requirements for optical signal quality. When the optical module loses its lock under the second setting condition, it means that the quality of the optical signal has deteriorated to the point where it is insufficient to maintain stable communication. In this case, in order to ensure that the optical module can lock onto the optimal signal during the next locking operation, the locking conditions of the optical module can be updated.

[0057] In one embodiment, after the "update the locking condition to the second set condition" part in step S2, the optical module locking control method provided by the present invention further includes the following steps.

[0058] Step S3': When the optical module loses its lock under the second set condition, update the locking condition to the first set condition.

[0059] In this way, by updating the locking conditions of the optical module, the continuous loss of lock of the optical module can be avoided, which helps the optical module to quickly restore communication and enhances the flexibility and stability of communication.

[0060] In this embodiment, step S3' indicates that when the quality of the optical signal received by the optical module deteriorates significantly (i.e., a loss of lock occurs) and the second setting condition is no longer met, the optical module will disconnect the signal lock. To facilitate re-locking the signal, the locking condition of the optical module is updated from the second setting condition to the first setting condition, so that it can re-lock onto an optical signal or electrical signal with better signal quality. Steps S1 to S3 or steps S1 to S3' are then repeated.

[0061] Steps S3 and S3' can be understood as two complementary parts of the optical module's signal locking control, together forming a dynamic signal locking and recovery mechanism. Step S3 allows the optical module to continue locking and processing the signal even when the signal quality is slightly poor; while step S3' provides a fault recovery mechanism, automatically switching to a higher signal quality standard and attempting to relock the signal when the optical module loses lock under the second set condition. Steps S3 and S3' can adaptively adjust the signal locking conditions according to actual conditions to adapt to different communication environments and requirements.

[0062] It should be noted that there is no single standard for measuring the quality of an optical signal. In the first embodiment, the first setting condition includes that the signal-to-noise ratio (SNR) of the optical signal is greater than or equal to a first SNR value, and the second setting condition includes that the SNR of the optical signal is greater than or equal to a second SNR value, wherein the first SNR value is higher than the second SNR value.

[0063] In the second embodiment, the first setting condition includes that the bit error rate of the optical signal is less than or equal to a first bit error rate, and the second setting condition includes that the bit error rate of the optical signal is less than or equal to a second bit error rate, wherein the first bit error rate is lower than the second bit error rate.

[0064] In the first embodiment, the signal-to-noise ratio (SNR) represents the ratio of signal power to noise power and is an important parameter for measuring signal quality. A higher SNR means that the signal is stronger relative to the noise, which helps to reduce signal distortion and interference during transmission and ensures that data is received accurately and reliably.

[0065] In a preferred embodiment, the first signal-to-noise ratio is 17dB and the second signal-to-noise ratio is 14dB.

[0066] In the second embodiment, the bit error rate (BER) represents the probability of erroneous symbols occurring during data transmission (i.e., the ratio of the number of errors to the total amount of data transmitted), which directly affects the accuracy and reliability of communication. Reducing the BER ensures that fewer errors occur during data transmission. Furthermore, reducing the BER helps reduce the need for data retransmission and correction, improves communication efficiency, and lowers the maintenance costs of optical modules.

[0067] In a preferred embodiment, the two embodiments described above can be used in combination. For example, the optical module locks onto the optical signal when the optical signal simultaneously meets the following conditions: bit error rate less than or equal to 1E-3 and signal-to-noise ratio greater than or equal to 14dB. This allows for a comprehensive and flexible evaluation of the communication quality and performance of the optical module.

[0068] It should be noted that if the signal-to-noise ratio of the optical signal does not meet the threshold set by the optical module, or if the bit error rate of the optical signal is too poor, causing the optical module to determine that the optical signal does not meet the conditions, these factors may lead to the optical module losing its lock. This invention can determine the second set condition by detecting the bit error rate and / or the optical signal's unlocked state.

[0069] In one embodiment, the first and second set conditions can be determined directly based on tests and statistical test results.

[0070] In one specific embodiment, the test optical module uses optical signals with different incident optical powers to transmit under a first set condition (first signal-to-noise ratio equal to 17dB) in a multipath interference environment with different power levels. It determines whether the bit error rate of the optical signal under each test condition meets a preset threshold, thereby determining the second set condition (second signal-to-noise ratio equal to 14dB).

[0071] In one specific embodiment, the test optical module transmits optical signals with different incident optical powers under a multipath interference environment with different power levels under a first set condition (a first signal-to-noise ratio of 17dB) to determine whether the optical signal is out of lock under each test condition, thereby determining a second set condition (a second signal-to-noise ratio of 14dB).

[0072] In one embodiment, the optical module includes a processing unit and a control unit. The processing unit receives optical signals and determines their quality. The control unit is coupled to the processing unit and adjusts the locking conditions of the optical module based on the processing results.

[0073] In one specific embodiment, a DSP (Digital Signal Processor) is used as the processing unit. DSPs possess efficient signal processing algorithms and computational capabilities, enabling them to complete signal quality assessment in a short time, thus improving processing efficiency and the reliability of processing results.

[0074] In one specific embodiment, an MCU (Microcontroller Unit) is used as the control unit. It is responsible for reading the processing results from the DSP and, based on the read results, sending corresponding control commands to the optical module to update the locking conditions or perform other operations.

[0075] like Figure 3 As shown, in one embodiment, the part of "controlling the optical module to lock the optical signal when the optical signal meets the first set condition" in step S2 of the present invention may specifically include the following steps.

[0076] Step S11: The control processing unit receives and determines whether the optical signal meets the first set condition;

[0077] If so, proceed to step S12A, whereby the processing unit sets the status flag to the first status value and locks the current optical signal based on the first status value.

[0078] If not, proceed to step S12B, whereby the processing unit sets the status flag to the second status value.

[0079] In this way, the status flag bit allows the processing unit (DSP) and control unit (MCU) in the optical module to quickly and directly identify whether the optical module is currently locked, without the need for complex judgment and calculation, simplifying the control logic and improving the response speed of the optical module.

[0080] In one specific embodiment, the processing unit (DSP) in the optical module determines whether the current optical signal meets a first set condition; if the current optical signal meets the first set condition, the processing unit locks the optical signal and sets the status flag to 0 (first status value).

[0081] In one specific embodiment, the processing unit (DSP) in the optical module determines whether the current optical signal meets the first set condition; if the current optical signal does not meet the first set condition, the processing unit sets the status flag to 1 (second status value).

[0082] In one specific embodiment, the processing unit (DSP) in the optical module determines whether the current optical signal meets the second set condition; if the current optical signal meets the second set condition, the processing unit locks the optical signal and sets the status flag to 0 (first status value).

[0083] In one specific embodiment, the processing unit (DSP) in the optical module determines whether the current optical signal meets the second set condition; if the current optical signal does not meet the second set condition, the processing unit sets the status flag to 1 (second status value).

[0084] The present invention sets a status value so that both the processing unit (DSP) and the subsequent control unit (MCU) can understand the current status of the optical module, and achieve alignment in status perception by controlling or reading the status value.

[0085] In one embodiment, the step S2 of the present invention, which involves "controlling the optical module to lock the optical signal when the optical signal meets the first set condition", may further include the following steps.

[0086] In step S2', the control unit reads the value of the status flag bit in the processing unit at a preset frequency and adjusts the locking condition of the optical module according to the value of the loading flag bit.

[0087] In this way, the locking conditions of the optical module can be quickly adjusted by reading the status flag, simplifying the control logic.

[0088] In one specific embodiment, when the value of the status flag bit is the first status value, the control unit adjusts the locking condition of the optical module to the second quality condition.

[0089] In one specific embodiment, when the value of the status flag bit is the second status value, the control unit adjusts the locking condition of the optical module to the first quality condition.

[0090] like Figure 4 As shown, in one specific embodiment, the first setting condition for the optical module is that the signal-to-noise ratio (SNR) of the optical signal is equal to 17dB (i.e., SNR = 17dB), and the second setting condition for the optical module is that the SNR of the optical signal is equal to 14dB (i.e., SNR = 14dB).

[0091] Continue to refer to Figure 4 As shown, it is determined whether the optical module has lost signal lock under the first set condition; if the optical module has not lost signal lock, the locking condition of the optical module is updated to the second set condition; when the optical module loses signal lock under the second set condition, the locking condition is readjusted from the second set condition to the first set condition.

[0092] One embodiment of the present invention provides a computer-readable storage medium.

[0093] In one embodiment, a computer-readable storage medium stores a computer program executed by the processor mentioned above, or the optical module locking control method in any of the preceding technical solutions.

[0094] When the processor executes the computer program, it can perform the description of the optical module locking control method in any of the preceding technical solutions; therefore, it will not be repeated here. Furthermore, the beneficial effects of using the same method will also not be repeated.

[0095] The computer-readable storage medium may include: flash drive, read-only memory (ROM), random access memory (RAM), magnetic disk or optical disk, etc.

[0096] In summary, the optical module locking control method, optical module, and computer storage medium provided by this invention lock the optical signal when the optical signal meets a first set condition, ensuring that the optical module can stably transmit high-quality optical signals, laying the foundation for subsequent signal processing and data transmission. While locking the optical signal, the locking conditions of the optical module are updated, allowing the optical module to maintain the locked state even when the optical signal quality slightly deteriorates. This effectively reduces the frequency of optical module outages caused by signal quality degradation. The optical module can better adapt to optical signals of different qualities, improving its robustness, stability, and reliability during communication, and enhancing user experience and satisfaction.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
