[0002] A coherent optical module includes a light source and a coherent optical component, and the light source is connected to the coherent optical component. The light emitted by the light source is incident into the coherent optical component, and the laser is split inside the coherent optical component. One of the split beams serves as the transmitted light and enters the coherent modulator inside the coherent optical component to achieve electro-optic signal conversion. The converted high-frequency optical signal is output from the optical transmission interface; the other split beam serves as the local oscillator light and is coherently demodulated with the high-frequency optical signal input from the optical reception interface into the coherent optical component to complete the optoelectronic signal conversion.

[0003] Due to the insufficient bandwidth of the laser driver chip and the coherent modulator, and the high-frequency damage introduced by the traces on the circuit board during the connection of the module, the spectrum of the high-frequency optical signal emitted by the coherent optical module often has deviations, resulting in an increase in the pre-error correction bit error rate, thereby reducing the quality and stability of optical communication.

[0019] Beneficial effects: The present application provides an optimization method for high-frequency electrical signal frequency control parameters based on an optical module. The optical module includes a digital signal processing chip and a coherent optical component. The digital signal processing chip is connected to the coherent optical component. The coherent optical component includes a coherent modulator. A plurality of high-frequency electrical signal frequency control parameters are set in the digital signal processing chip. The digital signal processing chip uses the high-frequency electrical signal frequency control parameters to perform frequency compensation on the high-frequency electrical signal. The compensated high-frequency electrical signal is transmitted to the coherent modulator so that the coherent modulator modulates and generates an optical signal. The optimization method includes: setting an initial value set of the high-frequency electrical signal frequency control parameters; traversing a plurality of high-frequency electrical signal frequency control parameters in sequence within a preset range to obtain a plurality of first pre-error correction codes; finding the smallest first pre-error correction code from the plurality of first pre-error correction codes after traversing one high-frequency electrical signal frequency control parameter; recording the real-time value of the high-frequency electrical signal frequency control parameter corresponding to the smallest first pre-error correction code as the first optimized value of the high-frequency electrical signal frequency control parameter to obtain a first optimized value set of the high-frequency electrical signal frequency control parameters. Among them, when one high-frequency electrical signal frequency control parameter is traversed, the other high-frequency electrical signal frequency control parameters remain unchanged at their initial values, indicating that each high-frequency electrical signal frequency control parameter is traversed independently. Although the first optimized value set of the high-frequency electrical signal frequency control parameters can be obtained by independently traversing each high-frequency electrical signal frequency control parameter, the mutual influence between the plurality of high-frequency electrical signal frequency control parameters is not considered, resulting in a relatively large pre-error correction code. To avoid this problem, after each high-frequency electrical signal frequency control parameter is independently traversed, at least one first optimized value of the high-frequency electrical signal frequency control parameter is selected from the first optimized value set of the high-frequency electrical signal frequency control parameters according to a preset combination method, and the selected first optimized value of the high-frequency electrical signal frequency control parameter is correspondingly replaced with the initial value of the high-frequency electrical signal frequency control parameter to obtain a plurality of second pre-error correction codes; the smallest second pre-error correction code is selected from the plurality of second pre-error correction codes to obtain a second optimized value set of the high-frequency electrical signal frequency control parameters corresponding to the smallest second pre-error correction code. In the present application, the local traversal method is first used to traverse a plurality of high-frequency electrical signal frequency control parameters in sequence. Each high-frequency electrical signal frequency control parameter is traversed independently to obtain a first optimized value set of the high-frequency electrical signal frequency control parameters, and then the first optimized value set of the high-frequency electrical signal frequency control parameters is combined according to a preset combination method to obtain a second optimized value set of the high-frequency electrical signal frequency control parameters corresponding to the smallest second pre-error correction code. In the present application, the high-frequency electrical signal frequency control parameters are optimized by using the local traversal and combination methods, and the optimal high-frequency electrical signal frequency control parameters can be obtained, thereby reducing the pre-error correction code of the optical module; compared with the method of optimizing the high-frequency electrical signal frequency control parameters by using the global variable method, the number of optimization times is effectively reduced and the optimization efficiency is improved.

However, the described embodiments are only some embodiments of the present disclosure, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments provided by the present disclosure fall within the scope of protection of the present disclosure.

[0033] In optical communication technology, in order to establish information transfer between information processing devices, it is necessary to load information onto light and utilize the propagation of light to achieve information transfer. Here, the light loaded with information is the optical signal. When the optical signal is transmitted in the information transmission device, the loss of optical power can be reduced, so high-speed, long-distance, and low-cost information transfer can be achieved. The signals that information processing devices can recognize and process are electrical signals. Information processing devices generally include an Optical Network Unit (ONU), gateway, router, switch, mobile phone, computer, server, tablet computer, television, etc., and information transmission devices generally include optical fibers and optical waveguides, etc.

[0034] The optical module can realize the mutual conversion between optical signals and electrical signals between the information processing device and the information transmission device. For example, at least one of the optical signal input end or the optical signal output end of the optical module is connected to an optical fiber, and at least one of the electrical signal input end or the electrical signal output end of the optical module is connected to an optical network terminal; the first optical signal from the optical fiber is transmitted to the optical module, the optical module converts the first optical signal into a first electrical signal, and transmits the first electrical signal to the optical network terminal; the second electrical signal from the optical network terminal is transmitted to the optical module, the optical module converts the second electrical signal into a second optical signal, and transmits the second optical signal to the optical fiber. Since information can be transmitted between multiple information processing devices through electrical signals, at least one of the multiple information processing devices needs to be directly connected to the optical module, rather than all information processing devices being directly connected to the optical module. Here, the information processing device directly connected to the optical module is called the host computer of the optical module. In addition, the optical signal input end or the optical signal output end of the optical module can be called an optical port, and the electrical signal input end or the electrical signal output end of the optical module can be called an electrical port.

[0035] Figure 1 Partial structural diagram of an optical communication system according to some embodiments. As Figure 1 shown, the optical communication system mainly includes a remote information processing device 1000, a local information processing device 2000, a host computer 100, an optical module 200, an optical fiber 101, and a network cable 103.

[0036] One end of the optical fiber 101 extends in the direction of the remote information processing device 1000, and the other end of the optical fiber 101 is connected to the optical module 200 through the optical port of the optical module 200. The optical signal can be totally reflected in the optical fiber 101, and the propagation of the optical signal in the total reflection direction can almost maintain the original optical power. The optical signal undergoes multiple total reflections in the optical fiber 101 to transmit the optical signal from the remote information processing device 1000 to the optical module 200, or to transmit the optical signal from the optical module 200 to the remote information processing device 1000, thereby realizing long-distance and low-power-loss information transmission.

[0037] The optical communication system may include one or more optical fibers 101, and the optical fiber 101 is detachably or fixedly connected to the optical module 200. The host computer 100 is configured to provide a data signal to the optical module 200, or receive a data signal from the optical module 200, or monitor or control the working state of the optical module 200.

[0038] The host computer 100 includes a housing generally in the shape of a rectangular parallelepiped, and an optical module interface 102 provided on the housing. The optical module interface 102 is configured to access the optical module 200 to establish a unidirectional or bidirectional electrical signal connection between the host computer 100 and the optical module 200.

[0039] The host computer 100 further includes an external power interface, which can access an electrical signal network. For example, the external power interface includes a Universal Serial Bus (USB) interface or a network cable interface 104, and the network cable interface 104 is configured to access a network cable 103, so that the host computer 100 establishes a unidirectional or bidirectional electrical signal connection with the network cable 103. One end of the network cable 103 is connected to the local information processing device 2000, and the other end of the network cable 103 is connected to the host computer 100, so as to establish an electrical signal connection between the local information processing device 2000 and the host computer 100 through the network cable 103. For example, a third electrical signal sent by the local information processing device 2000 is transmitted into the host computer 100 through the network cable 103, the host computer 100 generates a second electrical signal according to the third electrical signal, the second electrical signal from the host computer 100 is transmitted to the optical module 200, the optical module 200 converts the second electrical signal into a second optical signal, and transmits the second optical signal to the optical fiber 101, and the second optical signal is transmitted in the optical fiber 101 to the remote information processing device 1000. For example, a first optical signal from the remote information processing device 1000 propagates through the optical fiber 101, the first optical signal from the optical fiber 101 is transmitted to the optical module 200, the optical module 200 converts the first optical signal into a first electrical signal, the optical module 200 transmits the first electrical signal to the host computer 100, the host computer 100 generates a fourth electrical signal according to the first electrical signal, and transmits the fourth electrical signal into the local information processing device 2000. It should be noted that the optical module is a tool for realizing the mutual conversion between optical signals and electrical signals. In the above process of converting optical signals and electrical signals, the information does not change, but the encoding and decoding methods of the information may change.

[0040] In addition to including an optical network terminal, the host computer 100 further includes an Optical Line Terminal (OLT), an Optical Network Terminal (ONT), or a data center server, etc.

[0041] Figure 2 It is a partial structure diagram of a host computer according to some embodiments. In order to clearly show the connection relationship between the optical module 200 and the host computer 100, Figure 2 only the structure of the host computer 100 related to the optical module 200 is shown. As Figure 2 shown, the host computer 100 further includes a PCB circuit board 105 disposed in the housing, a cage 106 disposed on the surface of the PCB circuit board 105, a radiator 107 disposed on the cage 106, and an electrical connector disposed inside the cage 106. The electrical connector is configured to access the electrical port of the optical module 200; the radiator 107 has raised structures such as fins for increasing the heat dissipation area.

[0042] The optical module 200 is inserted into the cage 106 of the host computer 100. The cage 106 fixes the optical module 200, and the heat generated by the optical module 200 is conducted to the cage 106 and then diffused through the heat sink 107. After the optical module 200 is inserted into the cage 106, the electrical port of the optical module 200 is connected to the electrical connector inside the cage 106, so as to establish a two-way electrical signal connection between the optical module 200 and the host computer 100. In addition, the optical port of the optical module 200 is connected to the optical fiber 101, so as to establish a two-way optical signal connection between the optical module 200 and the optical fiber 101.

[0043] Figure 3 It is a structural diagram of an optical module according to some embodiments. Figure 4 It is an exploded structural diagram of the optical module according to some embodiments. As Figure 3 and 4 shown, the optical module 200 includes a shell, a circuit board 300, a light source 901 and a coherent optical component 902 disposed in the shell.

[0044] The shell includes an upper shell 201 and a lower shell 202. The upper shell 201 covers the lower shell 202 to form the above-mentioned shell with two openings 204 and 205; the outer contour of the shell generally presents a rectangular body.

[0045] In some embodiments, the lower shell 202 includes a bottom plate 2021 and two lower side plates 2022 located on both sides of the bottom plate 2021 and perpendicular to the bottom plate 2021; the upper shell 201 includes a cover plate 2011, and the cover plate 2011 covers the two lower side plates 2022 of the lower shell 202 to form the above-mentioned shell.

[0046] In some embodiments, the lower shell 202 includes a bottom plate 2021 and two lower side plates 2022 located on both sides of the bottom plate 2021 and perpendicular to the bottom plate 2021; the upper shell 201 includes a cover plate 2011 and two upper side plates located on both sides of the cover plate 2011 and perpendicular to the cover plate 2011. The two upper side plates are combined with the two lower side plates 2022 to realize the upper shell 201 covering the lower shell 202.

[0047] The direction where the line connecting the two openings 204 and 205 is located may be consistent with the length direction of the optical module 200 or may not be consistent with the length direction of the optical module 200. For example, the opening 204 is located at the end of the optical module 200 ( Figure 3 right end), and the opening 205 is also located at the end of the optical module 200 ( Figure 3The left end). Alternatively, the opening 204 is located at the end of the optical module 200, while the opening 205 is located on the side of the optical module 200. The opening 204 is an electrical port, and the gold finger of the circuit board 300 extends out from the electrical port and is inserted into the electrical connector of the host computer 100; the opening 205 is an optical port and is configured to access an external optical fiber 101 so that the optical fiber 101 is connected to the coherent optical component 902 in the optical module 200.

[0048] The assembly method of combining the upper housing 201 and the lower housing 202 facilitates the installation of the circuit board 300, the coherent optical component 902, etc. into the above-mentioned housing, and the upper housing 201 and the lower housing 202 can encapsulate and protect the above-mentioned devices. In addition, when assembling the circuit board 300, the coherent optical component 902, etc., it is convenient to deploy the positioning components, heat dissipation components, and electromagnetic shielding components of these devices, which is beneficial to the automated implementation of production.

[0049] In some embodiments, the upper housing 201 and the lower housing 202 are made of a metal material, which is beneficial to achieving electromagnetic shielding and heat dissipation.

[0050] In some embodiments, the optical module 200 further includes an unlocking component 600 located outside its housing. The unlocking component 600 is configured to achieve a fixed connection between the optical module 200 and the host computer, or to release the fixed connection between the optical module 200 and the host computer.

[0051] For example, the unlocking component 600 is located outside the two lower side plates 2022 of the lower housing 202 and includes an engaging component that matches the cage 106 of the host computer 100. When the optical module 200 is inserted into the cage 106, the engaging component of the unlocking component 600 fixes the optical module 200 in the cage 106; when the unlocking component 600 is pulled, the engaging component of the unlocking component 600 moves accordingly, thereby changing the connection relationship between the engaging component and the host computer to release the fixation of the optical module 200 and the host computer, so that the optical module 200 can be withdrawn from the cage 106.

[0052] The circuit board 300 includes circuit traces, electronic components, chips, etc. The electronic components and chips are connected according to the circuit design through the circuit traces to achieve functions such as power supply, electrical signal transmission, and grounding. The electronic components may include, for example, capacitors, resistors, triodes, Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs). The chips may include, for example, Microcontroller Units (MCUs), laser driver chips, Transimpedance Amplifiers (TIAs), limiting amplifiers, Clock and Data Recovery (CDR) chips, power management chips, and Digital Signal Processing (DSP) chips.

[0053] The circuit board 300 is generally a rigid circuit board. Due to its relatively hard material, the rigid circuit board can also achieve a bearing function. For example, the rigid circuit board can stably bear the above-mentioned electronic components and chips; the rigid circuit board can also be inserted into the electrical connector in the cage 106 of the host computer 100.

[0054] The circuit board 300 also includes a gold finger formed on its end surface. The gold finger is composed of a plurality of independent pins. The circuit board 300 is inserted into the cage 106, and the gold finger is electrically connected to the electrical connector in the cage 106. The gold finger can be provided only on the surface of one side of the circuit board 300 (for example, Figure 4 the upper surface shown), or can be provided on the upper and lower surfaces of the circuit board 300 to provide a larger number of pins, so as to adapt to occasions with a large demand for the number of pins. The gold finger is configured to establish an electrical connection with the host computer to achieve functions such as power supply, grounding, Inter-Integrated Circuit (I2C) signal transmission, and data signal transmission. Of course, flexible circuit boards are also used in some optical modules. The flexible circuit board is generally used in cooperation with the rigid circuit board as a supplement to the rigid circuit board.

[0055] Of course, flexible circuit boards are also used in some optical modules. The flexible circuit board is generally used in cooperation with the rigid circuit board as a supplement to the rigid circuit board.

[0056] The light source 901 is connected to the circuit board 300 and is used to emit light.

[0057] The optical module further includes a transmitting fiber optic adapter 700 and a receiving fiber optic adapter 701. The transmitting fiber optic adapter 700 is used to transmit high-frequency optical signals, and the receiving fiber optic adapter 701 is used to receive high-frequency optical signals.

[0058] The coherent optical component 902 is placed on the circuit board and is used to implement the conversion of high-speed optoelectronic signals. Specifically, the coherent optical component 902 includes an optical transmission interface, an optical reception interface, and a local oscillator optical interface. The optical transmission interface extends out a first optical fiber, the optical reception interface extends out a second optical fiber, and the local oscillator optical interface extends out a third optical fiber. The optical transmission interface is connected to the transmitting fiber optic adapter 700, the optical reception interface is connected to the receiving fiber optic adapter 701, and the local oscillator optical interface is connected to the light source 901. The coherent optical component is connected to the transmitting fiber optic adapter, the receiving fiber optic adapter, and the light source 901 through the optical transmission interface, the optical reception interface, and the local oscillator optical interface respectively. The coherent optical component 902 is also connected to the DSP chip 301.

[0059] The light emitted by the light source 901 is input into the coherent optical component 902 through the local oscillator optical interface, and the laser is split inside the coherent optical component 902. One of the beams is used as the transmitted beam and enters the coherent modulator inside the coherent optical component. Under the drive of the high-frequency electrical signal of the DSP chip 301, the electro-optical signal conversion is realized, and the converted high-frequency optical signal is output from the optical transmission interface of the module; the other beam is used as the local oscillator beam and is coherently demodulated with the high-frequency optical signal input into the coherent optical component 902 from the optical reception port of the module. The demodulated electrical signal enters the DSP chip 301 for signal processing, thus completing the optoelectronic signal conversion.

[0060] Due to the insufficient bandwidth of the laser driver chip and the coherent modulator, and the high-frequency damage introduced by the traces on the circuit board during the connection of the module, the spectrum of the high-frequency optical signal emitted by the coherent optical module often has deviations, resulting in an increase in the pre-correction bit error rate, thereby reducing the quality and stability of optical communication. To solve this problem, the conventional method is to use the global traversal method to optimize the frequency control parameters of the high-frequency electrical signal. However, it is difficult and inefficient to use the global traversal method to optimize the frequency control parameters of the high-frequency electrical signal. To solve this problem, the test host uses the local traversal + preset combination method to optimize the frequency control parameters of the high-frequency electrical signal.

As Figure 5As shown, the optical module has a gold finger, and the test host is connected to the optical module through the gold finger. The test host includes a processor, and the processor is configured to: set an initial value set of high-frequency electrical signal frequency control parameters; traverse multiple high-frequency electrical signal frequency control parameters in a preset range in sequence to obtain multiple first pre-error-correction codes; where, when one high-frequency electrical signal frequency control parameter is traversed, the other high-frequency electrical signal frequency control parameters remain unchanged at their initial values; find the smallest first pre-error-correction code from the multiple first pre-error-correction codes obtained after traversing one high-frequency electrical signal frequency control parameter; record the real-time value of the high-frequency electrical signal frequency control parameter corresponding to the smallest first pre-error-correction code as the first optimized value of the high-frequency electrical signal frequency control parameter, so as to obtain a first optimized value set of the high-frequency electrical signal frequency control parameters; select at least one first optimized value of the high-frequency electrical signal frequency control parameter from the first optimized value set of the high-frequency electrical signal frequency control parameters according to a preset combination method, and replace the initial value of the high-frequency electrical signal frequency control parameter with the selected first optimized value of the high-frequency electrical signal frequency control parameter to obtain multiple second pre-error-correction codes; select the smallest second pre-error-correction code from the multiple second pre-error-correction codes to obtain a second optimized value set of the high-frequency electrical signal frequency control parameter corresponding to the smallest second pre-error-correction code.

[0062] The processor is further configured to: determine whether the real-time value of the high-frequency electrical signal frequency control parameter corresponding to the smallest first pre-error-correction code is a minimum point; if the real-time value of the high-frequency electrical signal frequency control parameter corresponding to the smallest first pre-error-correction code is not a minimum point, use the real-time value of the high-frequency electrical signal frequency control parameter corresponding to the smallest first pre-error-correction code as the initial value, and the high-frequency electrical signal frequency control parameter starts traversing again until the real-time value of the high-frequency electrical signal frequency control parameter corresponding to the smallest pre-error-correction code is a minimum point; if the real-time value of the high-frequency electrical signal frequency control parameter corresponding to the smallest first pre-error-correction code is a minimum point, record the real-time value of the high-frequency electrical signal frequency control parameter corresponding to the smallest first pre-error-correction code as the first optimized value of the high-frequency electrical signal frequency control parameter, so as to obtain a first optimized value set of the high-frequency electrical signal frequency control parameters.

[0065] The processor sets an initial value set for the high-frequency electrical signal frequency control parameters, and each high-frequency electrical signal frequency control parameter has an initial value. For example, in the low sampling mode, there are 7 high-frequency electrical signal frequency control parameters set in the DSP, and the initial value set given by the processor to the 7 high-frequency electrical signal frequency control parameters is 0 0 0 127 0 0 0. The initial value of the first high-frequency electrical signal frequency control parameter is 0, the initial value of the second high-frequency electrical signal frequency control parameter is 0, the initial value of the third high-frequency electrical signal frequency control parameter is 0, the initial value of the fourth high-frequency electrical signal frequency control parameter is 127, the initial value of the fifth high-frequency electrical signal frequency control parameter is 0, the initial value of the sixth high-frequency electrical signal frequency control parameter is 0, and the initial value of the seventh high-frequency electrical signal frequency control parameter is 0.

[0066] S200: Within a preset range, multiple high-frequency electrical signal frequency control parameters are traversed in sequence to obtain multiple first pre-error correction codes.

[0067] S201: Within a preset range, multiple high-frequency electrical signal frequency control parameters are traversed in sequence to obtain a set of real-time value sets of multiple high-frequency electrical signal frequency control parameters.

[0068] The preset range is the traversal range, and the traversal range of each high-frequency electrical signal frequency control parameter is M, that is, each high-frequency electrical signal frequency control parameter traverses within the range of Fn0 - M to Fn0 + M. Among them, Fn is the nth high-frequency electrical signal frequency control parameter, and Fn0 is the initial value of the nth high-frequency electrical signal frequency control parameter.

[0069] The range of each high-frequency electrical signal frequency control parameter is 0 to 511. When Fni is less than 0, Fni = Fni + 512; when Fni is greater than 511, Fni = Fni - 512. Among them, Fni is the real-time value of the nth high-frequency electrical signal frequency control parameter at the ith point.

[0070] The traversal step size of the high-frequency electrical signal frequency control parameter is a second preset value. For example, the second preset value is 2, and the traversal step size of the high-frequency electrical signal frequency control parameter is 2.

[0071] The preset traversal order is the order in which the high-frequency electrical signal frequency control parameters perform frequency compensation on the high-frequency electrical signal. For example, the preset traversal order is 1, 2, 3, 4, 5, 6, 7.

[0072] The preset traversal order is the order of the weights of the high-frequency electrical signal frequency control parameters. For example, the preset traversal order is 4, 3, 5, 2, 6, 1, 7.

[0073] Within the traversal range, the processor traverses multiple high-frequency electrical signal frequency control parameters in sequence according to a preset traversal order. Each high-frequency electrical signal frequency control parameter is traversed independently, and multiple first error codes before correction are obtained. For example, the preset traversal order is 1, 2, 3, 4, 5, 6, 7. The first high-frequency electrical signal frequency control parameter F1, the second high-frequency electrical signal frequency control parameter F2, the third high-frequency electrical signal frequency control parameter F3, the fourth high-frequency electrical signal frequency control parameter F4, the fifth high-frequency electrical signal frequency control parameter F5, the sixth high-frequency electrical signal frequency control parameter F6, and the seventh high-frequency electrical signal frequency control parameter F7 are traversed in sequence; the preset traversal order is 4, 3, 5, 2, 6, 1, 7. The fourth high-frequency electrical signal frequency control parameter F4, the third high-frequency electrical signal frequency control parameter F3, the fifth high-frequency electrical signal frequency control parameter F5, the second high-frequency electrical signal frequency control parameter F2, the sixth high-frequency electrical signal frequency control parameter F6, the first high-frequency electrical signal frequency control parameter F1, and the seventh high-frequency electrical signal frequency control parameter F7 are traversed in sequence.

[0074] The preset traversal order affects the size of the preset traversal range. For example, when the preset traversal order is 1, 2, 3, 4, 5, 6, 7, the preset traversal range of all high-frequency electrical signal frequency control parameters is the first value. When the preset traversal order is 4, 3, 5, 2, 6, 1, 7, the traversal ranges of the high-frequency electrical signal frequency control parameters decrease in sequence. That is, the preset traversal range of F4 is the first value, the preset traversal range of F3 is the second value, the preset traversal range of F5 is the third value, the preset traversal range of F2 is the fourth value, the preset traversal range of F6 is the fifth value, the preset traversal range of F1 is the sixth value, and the preset traversal range of F7 is the seventh value, where the first value > the second value > the third value > the fourth value > the fifth value > the sixth value > the seventh value.

[0075] When one high-frequency electrical signal frequency control parameter is traversed, the other high-frequency electrical signal frequency control parameters remain unchanged at their initial values. For example, when traversing the second high-frequency electrical signal frequency control parameter F2, the other high-frequency electrical signal frequency control parameters are F1 = 0, F3 = 0, F4 = 127, F5 = 0, F6 = 0, F7 = 0.

[0076] S202: Send the real-time value sets of multiple groups of high-frequency electrical signal frequency control parameters.

[0077] After the processor sends a real-time value set of a group of high-frequency electrical signal frequency control parameters, the processor sends an initialization instruction. After receiving the initialization instruction, the MCU of the optical module completes the initialization and changes the initialization parameters from the first value to the second value in the register of the MCU. The processor periodically reads the initialization parameters in the register.

[0078] S203: When the initialization parameter read is the second value, read the first pre-error correction code multiple times and record the last read first pre-error correction code.

[0079] The processor reads that the initialization parameter is the second value, reads the first pre-error correction code multiple times, and records the last read first pre-error correction code.

[0080] After the processor issues a set of real-time value sets of high-frequency electrical signal frequency control parameters each time, the processor will issue an initialization parameter instruction again to facilitate reading multiple first pre-error correction codes.

[0081] S300: Find the smallest first pre-error correction code from multiple first pre-error correction codes obtained after traversing a high-frequency electrical signal frequency control parameter.

[0082] Each high-frequency electrical signal frequency control parameter is traversed independently, and multiple first pre-error correction codes are obtained after traversing. The processor finds the smallest first pre-error correction code from multiple first pre-error correction codes obtained after traversing a high-frequency electrical signal frequency control parameter.

[0083] S400: Determine whether the real-time value of the high-frequency electrical signal frequency control parameter corresponding to the smallest first pre-error correction code is a minimum point.

[0084] Since the traversal range of each high-frequency electrical signal frequency control parameter is limited, the smallest first pre-error correction code obtained by traversing the high-frequency electrical signal frequency control parameter within the traversal range may not be the smallest first pre-error correction code after traversing all values of the high-frequency electrical signal frequency control parameter. Therefore, after obtaining the smallest first pre-error correction code, it is necessary to determine whether the real-time value of the high-frequency electrical signal frequency control parameter corresponding to the smallest first pre-error correction code is a minimum point.

[0085] The processor determines whether the real-time value of the high-frequency electrical signal frequency control parameter corresponding to the smallest first pre-error correction code is a minimum point.

[0086] S500: If the real-time value of the high-frequency electrical signal frequency control parameter corresponding to the smallest first pre-error correction code is not a minimum point, use the real-time value of the high-frequency electrical signal frequency control parameter corresponding to the smallest first pre-error correction code as the initial value, and the high-frequency electrical signal frequency control parameter starts traversing again until the real-time value of the high-frequency electrical signal frequency control parameter corresponding to the smallest pre-error correction code is a minimum point.

[0087] If the real-time value of the high-frequency electrical signal frequency control parameter corresponding to the smallest first pre-error correction code is not a minimum point, the processor uses the real-time value of the high-frequency electrical signal frequency control parameter corresponding to the smallest first pre-error correction code as the initial value, and this high-frequency electrical signal frequency control parameter starts traversing again until the real-time value of the high-frequency electrical signal frequency control parameter corresponding to the smallest pre-error correction code is a minimum point.

[0088] S600: If the real-time value of the high-frequency electrical signal frequency control parameter corresponding to the smallest first pre-error correction code is the minimum point, record the real-time value of the high-frequency electrical signal frequency control parameter corresponding to the smallest first pre-error correction code as the first optimization value of the high-frequency electrical signal frequency control parameter, so as to obtain the first optimization value set of the high-frequency electrical signal frequency control parameter.

[0089] Figure 9 It is the fourth flowchart of the optimization method for the high-frequency electrical signal frequency control parameter provided according to some embodiments. As Figure 9 shown, recording the real-time value of the high-frequency electrical signal frequency control parameter corresponding to the smallest first pre-error correction code as the first optimization value of the high-frequency electrical signal frequency control parameter to obtain the first optimization value set of the high-frequency electrical signal frequency control parameter includes:

[0090] S601: If the real-time value of the high-frequency electrical signal frequency control parameter corresponding to the smallest first pre-error correction code is the minimum point, the processor records the real-time value of the high-frequency electrical signal frequency control parameter corresponding to the smallest first pre-error correction code as the first optimization value of the high-frequency electrical signal frequency control parameter.

[0091] The first optimization value of the nth high-frequency electrical signal frequency control parameter is F ni-best .

[0092] S602: Combine the first optimization values of multiple high-frequency electrical signal frequency control parameters to obtain the first optimization value set of the high-frequency electrical signal frequency control parameter.

[0093] Traverse one high-frequency electrical signal frequency control parameter to obtain the first optimization value of one high-frequency electrical signal frequency control parameter, and traverse multiple high-frequency electrical signal frequency control parameters to obtain the first optimization value set of the high-frequency electrical signal frequency control parameter. Exemplarily, there are 7 high-frequency electrical signal frequency control parameters set in the DSP, and the first optimization value set of the high-frequency electrical signal frequency control parameter is (F 1i-best , F 2i-best , F 3i-best , F 4i-best , F 5i-best , F 6i-best , F 7i-best ).

[0094] When traversing one high-frequency electrical signal frequency control parameter, the other high-frequency electrical signal frequency control parameters remain unchanged at their initial values, indicating that each high-frequency electrical signal frequency control parameter is traversed independently. Although the first optimization value set of the high-frequency electrical signal frequency control parameter can also be obtained by traversing each high-frequency electrical signal frequency control parameter independently, the mutual influence between multiple high-frequency electrical signal frequency control parameters is not considered, resulting in a relatively large pre-error correction code. To solve this problem, the optimization method further includes:

[0095] S700: Select at least one first optimized value of the high-frequency electrical signal frequency control parameter from the first set of optimized values of the high-frequency electrical signal frequency control parameter according to a preset combination method, and correspondingly replace the initial value of the high-frequency electrical signal frequency control parameter with the selected first optimized value of the high-frequency electrical signal frequency control parameter to obtain multiple second pre-error correction codes.

As Figure 10 shown, select at least one first optimized value of the high-frequency electrical signal frequency control parameter from the first set of optimized values of the high-frequency electrical signal frequency control parameter according to a preset combination method, and correspondingly replace the initial value of the high-frequency electrical signal frequency control parameter with the selected first optimized value of the high-frequency electrical signal frequency control parameter to obtain multiple second pre-error correction codes, including:

[0097] S701: Select at least one first optimized value of the high-frequency electrical signal frequency control parameter from the first set of optimized values of the high-frequency electrical signal frequency control parameter according to a preset combination method.

[0098] The preset combination method is to select 1 to N first optimized values of the high-frequency electrical signal frequency control parameter from the first optimized values of N high-frequency electrical signal frequency control parameters for combination.

[0099] There are N high-frequency electrical signal frequency control parameters set in the DSP. The preset combination method is to read 1 from the first optimized values of N high-frequency electrical signal frequency control parameters for combination + read 2 from the first optimized values of N high-frequency electrical signal frequency control parameters for combination + read 3 from the first optimized values of N high-frequency electrical signal frequency control parameters for combination +... + read N - 3 from the first optimized values of N high-frequency electrical signal frequency control parameters for combination + read N - 2 from the first optimized values of N high-frequency electrical signal frequency control parameters for combination + read N - 1 from the first optimized values of N high-frequency electrical signal frequency control parameters for combination + read N from the first optimized values of N high-frequency electrical signal frequency control parameters for combination. Exemplarily, there are 7 high-frequency electrical signal frequency control parameters set in the DSP. The preset combination method is to read 1 from the first optimized values of 7 high-frequency electrical signal frequency control parameters for combination + read 2 from the first optimized values of 7 high-frequency electrical signal frequency control parameters for combination + read 3 from the first optimized values of 7 high-frequency electrical signal frequency control parameters for combination +... + read 4 from the first optimized values of 7 high-frequency electrical signal frequency control parameters for combination + read 5 from the first optimized values of 7 high-frequency electrical signal frequency control parameters for combination + read 6 from the first optimized values of 7 high-frequency electrical signal frequency control parameters for combination + read 7 from the first optimized values of 7 high-frequency electrical signal frequency control parameters for combination.

[0100] S702: Replace the initial value of the high-frequency electrical signal frequency control parameter with the first optimized value of the selected high-frequency electrical signal frequency control parameter to obtain a set of real-time values of the high-frequency electrical signal frequency control parameter.

[0103] S800: Select the smallest second pre-error correction code from multiple second pre-error correction codes to obtain a set of second optimized values of the high-frequency electrical signal frequency control parameter corresponding to the smallest second pre-error correction code.

[0104] In some embodiments, an optimization method for the high-frequency electrical signal frequency control parameters of an optical module, the optimization method includes: setting an initial value set of the high-frequency electrical signal frequency control parameters; traversing multiple high-frequency electrical signal frequency control parameters in sequence within a preset range to obtain multiple first pre-correction error codes; finding the smallest first pre-correction error code from the multiple first pre-correction error codes after traversing one high-frequency electrical signal frequency control parameter; recording the real-time value of the high-frequency electrical signal frequency control parameter corresponding to the smallest first pre-correction error code as the first optimized value of the high-frequency electrical signal frequency control parameter, so as to obtain a first optimized value set of the high-frequency electrical signal frequency control parameters. Among them, when traversing one high-frequency electrical signal frequency control parameter, the other high-frequency electrical signal frequency control parameters remain unchanged at their initial values, indicating that each high-frequency electrical signal frequency control parameter is traversed independently. Although the first optimized value set of the high-frequency electrical signal frequency control parameters can also be obtained by independently traversing each high-frequency electrical signal frequency control parameter, the mutual influence between multiple high-frequency electrical signal frequency control parameters is not considered, resulting in a relatively large pre-correction error code. To avoid this problem, after independently traversing each high-frequency electrical signal frequency control parameter, at least one first optimized value of the high-frequency electrical signal frequency control parameter is selected from the first optimized value set of the high-frequency electrical signal frequency control parameters according to a preset combination method, and the selected first optimized value of the high-frequency electrical signal frequency control parameter is correspondingly used to replace the initial value of the high-frequency electrical signal frequency control parameter to obtain multiple second pre-correction error codes; the smallest second pre-correction error code is selected from the multiple second pre-correction error codes, so as to obtain a second optimized value set of the high-frequency electrical signal frequency control parameters corresponding to the smallest second pre-correction error code. In some embodiments, first, the local traversal method is used to sequentially traverse multiple high-frequency electrical signal frequency control parameters, and each high-frequency electrical signal frequency control parameter is traversed independently to obtain a first optimized value set of the high-frequency electrical signal frequency control parameters, and then the first optimized value set of the high-frequency electrical signal frequency control parameters is combined according to a preset combination method to obtain a second optimized value set of the high-frequency electrical signal frequency control parameters corresponding to the smallest second pre-correction error code. In some embodiments, by using the local traversal and combination method to optimize the high-frequency electrical signal frequency control parameters, the optimal high-frequency electrical signal frequency control parameters can be obtained, thereby reducing the pre-correction error code of the optical module; compared with the method of optimizing the high-frequency electrical signal frequency control parameters by using the global variable method, the number of optimization times is effectively reduced, and the optimization efficiency is improved.

[0105] In addition to providing an optimization method for the high-frequency electrical signal frequency control parameters based on an optical module, the present application also provides an optimization device for the high-frequency electrical signal frequency control parameters based on an optical module.
