[0002] In optical fiber communication, the optical modules on the link mainly receive and forward data, and the relevant parameters of the optical receiving end of the optical module cannot be transmitted. By means of tone topping, the information of the optical module is loaded onto the data signal and transmitted using the data signal as the carrier signal, so that both optical modules at both ends can obtain the relevant parameters of the optical receiving end of the optical module at the opposite end, thereby achieving the purpose of managing the optical module at the opposite end and optimizing the local optical module by using the information of the opposite-end device.
[0003] However, when the information of the optical module is loaded onto the data signal by tone topping technology, a certain tone topping cost will be generated, which deteriorates the transmission performance of the communication system when communicating between two communication devices in the communication system.

[0023] The following will describe in detail some embodiments of the present invention with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.
[0024] Please refer to Figure 1 , Figure 1 which is a schematic structural block diagram of a communication system provided by an embodiment of the present invention.
[0025] As Figure 1As shown, the communication system 100 includes a first communication device 101 and a second communication device 201 communicatively connected to the first communication device 101 via an optical fiber network. The first communication device 101 and the second communication device 201 can mutually monitor whether the communication signals transmitted and received by each other are stable. Exemplarily, the first communication device 101 converts the first device information into a corresponding first tone signal, loads it onto the carrier signal, and modulates it into a corresponding first optical communication signal λ1 and sends it to the second communication device 201. The first device information is used to evaluate the signal transmission stability between the first communication device 101 and the second communication device 201, and the first device information includes at least one of the bit error rate, signal-to-noise ratio, received optical power of the signal received by the receiving end of the first optical interface 1019 of the first communication device 101, and eye diagram sampling data. The second communication device 201 receives the first optical communication signal λ1 sent by the first communication device 101 through the second optical interface 2019, analyzes the first tone signal transmitted by the first communication device 101 using the first optical communication signal λ1, and adjusts the amplification gain of the carrier signal of the second communication device 201 according to the obtained first tone signal, so that the signal amplitude of the carrier signal of the second communication device 201 meets the preset standard, thereby effectively reducing the influence of the first tone signal on the carrier signal. The first optical communication signal is an optical modulation signal including at least the carrier signal and the first tone signal.
[0026] In some embodiments, the second communication device 201 can obtain the corresponding first device information according to the first tone signal, and use the first device information to optimize the relevant parameters of the second communication device 201, and / or generate corresponding feedback information according to the first device information and send it to the first communication device 101, so that the first communication device 101 optimizes the relevant parameters of the first communication device 101 according to the feedback information, thereby making the signal transmission stability between the first communication device 101 and the second communication device 201 stronger.
[0027] At the same time, the second communication device 201 converts the second device information into a corresponding second tone signal, loads it onto the carrier signal, and modulates it into a corresponding second optical communication signal λ2 and sends it to the first communication device 101 through the second optical interface 2019. The second device information is used to evaluate the signal transmission stability between the second communication device 201 and the first communication device 101, and the second device information includes at least one of the bit error rate, signal-to-noise ratio, received optical power of the signal received by the receiving end of the second optical interface 2019 of the second communication device 201, and eye diagram sampling data.
[0028] The first communication device 101 receives the second optical communication signal λ2 sent by the second communication device 201, analyzes the second tone signal transmitted by the second communication device 201 by using the second optical communication signal λ2, and adjusts the amplification gain of the carrier signal of the first communication device 101 according to the obtained second tone signal, so that the signal amplitude of the carrier signal of the first communication device 101 meets the preset standard, thereby effectively reducing the influence of the second tone signal on the carrier signal. The second optical communication signal is an optical modulation signal that at least includes a carrier signal and the second tone signal.
[0029] In some embodiments, the first communication device 101 may obtain corresponding second device information according to the second tone signal, and optimize the relevant parameters of the first communication device 101 by using the second device information, and / or generate corresponding feedback information according to the second device information and send it to the second communication device 201, so that the second communication device 201 optimizes the relevant parameters of the second communication device 201 according to the feedback information, thereby making the signal transmission between the first communication device 101 and the second communication device 201 more stable.
[0030] Both the first communication device 101 and the second communication device 201 can receive and transmit optical signals. That is, the first communication device 101 and the second communication device 201 can be optical modules or communication devices with optical modules. Preferably, both the first communication device 101 and the second communication device 201 are PAM4 optical modules.
[0031] Please refer to Figure 2 , Figure 2 the schematic diagram of signal transmission between the first communication device and the second communication device in the communication system provided by the embodiment of the present invention.
[0032] As Figure 2 shown, the first communication device 101 includes a first electrical interface 1011, a first DSP (Digital Signal Processing) unit 1012, a first electro-optical (E / O) converter 1013, a first opto-electrical (O / E) converter 1014, a first tone unit 1015, a first optical splitter 1016, a first gain controller 1017, a first optical amplifier 1018, and a first optical interface 1019.
[0033] The second communication device 201 includes a second electrical interface 2011, a second DSP (Digital Signal Processing) unit 2012, a second electro-optical (E / O) converter 2013, a second opto-electrical (O / E) converter 2014, a second peak clipping unit 2015, a second optical splitter 2016, a second gain controller 2017, a second optical amplifier 2018, and a second optical interface 2019.
[0034] The first optical interface 1019 and the second optical interface 2019 are used to receive or transmit optical signals. When the second communication device 201 receives the first optical communication signal λ1 sent by the first communication device 101 through the second optical interface 2019, the first optical communication signal λ1 is split by the second optical splitter 2016, and a preset proportion of the first optical communication signal λ1 is output to the second opto-electrical converter 2014 for opto-electrical conversion, so as to convert a preset proportion of the first optical communication signal λ1 into a corresponding electrical signal, thereby identifying the signal parameters corresponding to the first peak clipping signal in the first optical communication signal λ1.
[0035] For example, 90% of the first optical communication signal λ1 is converted into a corresponding electrical signal. Since the frequencies of the carrier signal and the first peak clipping signal are different, the electrical signal parameters such as the signal amplitude and signal length corresponding to the electrical signal obtained after opto-electrical conversion are also different. Therefore, the second opto-electrical converter 2014 can identify the first electrical signal corresponding to the first peak clipping signal in the first optical communication signal λ1 after opto-electrical conversion by identifying the electrical signal parameters of the corresponding electrical signals generated by the carrier signal and the first peak clipping signal after opto-electrical conversion, and obtain the signal parameters such as the signal amplitude and signal length of the first electrical signal.
[0036] The second optical splitter 2016 outputs the remaining proportion of the first optical communication signal λ1 to the second optical amplifier 2018 to adaptively amplify the carrier signal of the first optical communication signal λ1 through the second optical amplifier 2018 to eliminate the influence of the first peak clipping signal on the carrier signal, where the first optical communication signal λ1 is an optical modulation signal at least including a carrier signal and a first peak clipping signal.
[0037] The second optical-electric converter 2014 outputs signal parameters such as the signal amplitude and signal length of the acquired first tone-top signal to the second gain controller 2017, and outputs the electric signal corresponding to the converted first tone-top signal to the second tone-top unit 2015. The second gain controller 2017 controls the amplification gain of the carrier signal of the first optical communication signal λ1 by the second amplifier 2018 by using signal parameters such as the signal amplitude and signal length of the first tone-top signal, so that the signal amplitude of the amplified carrier signal conforms to a preset standard, and a stable output carrier signal is obtained.
[0038] The second tone-top unit 2015 demodulates the electric signal to obtain the corresponding first device information, and adaptively adjusts the relevant parameters of the transmitting end of the second optical interface 2019 of the second communication device 201 according to the first device information.
[0039] In some embodiments, the second communication device 201 generates corresponding feedback information according to the adaptive adjustment result, and sends the feedback information to the first communication device 101, so that the first communication device 101 adaptively adjusts the equalization parameters of the first optical interface 1019, making the signal transmission between the first communication device 101 and the second communication device 201 more stable.
[0040] Similarly, when the first communication device 101 receives the second optical communication signal λ2 sent by the second communication device 201 through the first optical interface 1019, the second optical communication signal λ2 is split by the first optical splitter 1016, and a preset proportion of the second optical communication signal λ2 is output to the first optical-electric converter 1014 for optical-electric conversion, so as to convert a preset proportion of the second optical communication signal λ2 into a corresponding electric signal, thereby identifying the signal parameters corresponding to the second tone-top signal in the second optical communication signal λ2.
[0041] For example, 90% of the second optical communication signal λ2 is converted into a corresponding electric signal. Since the frequencies of the carrier signal and the second tone-top signal are different, the electric signal parameters such as the signal amplitude and signal length of the corresponding electric signal obtained after optical-electric conversion are also different. Therefore, the first optical-electric converter 1014 can identify the second electric signal corresponding to the second tone-top signal after optical-electric conversion by identifying the electric signal parameters of the corresponding electric signals generated by the carrier signal and the second tone-top signal in the second optical communication signal λ2 after optical-electric conversion, and obtain signal parameters such as the signal amplitude and signal length of the second electric signal.
[0042] The first optical splitter 1016 outputs the remaining proportion of the second optical communication signal λ2 to the first optical amplifier 1018, so as to adaptively amplify the carrier signal of the second optical communication signal λ2 through the first optical amplifier 1018 to eliminate the influence of the second tone-top signal on the carrier signal, where the second optical communication signal λ2 is an optical modulation signal including at least a carrier signal and a second tone-top signal.
[0043] The first optical-electric converter 1014 outputs signal parameters such as the signal amplitude and signal length of the obtained second tone-top signal to the first gain controller 1017, and outputs the electric signal corresponding to the converted second tone-top signal to the first tone-top unit 1015. The first gain controller 1017 controls the amplification gain of the carrier signal of the second optical communication signal λ2 by the first amplifier 1018 by using signal parameters such as the signal amplitude and signal length of the second tone-top signal, so that the signal amplitude of the amplified carrier signal meets the preset standard, and a stable output carrier signal is obtained, making the signal transmission between the first communication device 101 and the second communication device 201 more stable.
[0044] The first tone-top unit 1015 demodulates the electric signal to obtain the corresponding second device information, and adaptively adjusts the relevant parameters of the transmitting end of the first optical interface 1019 of the first communication device 101 through the second device information, making the signal transmission between the first communication device 101 and the second communication device 201 more stable.
[0045] In some embodiments, the first communication device 101 generates corresponding feedback information according to the adaptive adjustment result, and sends the feedback information to the second communication device 201, so that the second communication device 201 adaptively adjusts the equalization parameters of the second optical interface 2019, making the signal transmission between the first communication device 101 and the second communication device 201 more stable.
[0046] Please refer to Figure 3 , Figure 3 which is a schematic flowchart of a communication method provided by an embodiment of the present invention.
[0047] As Figure 3 shown, the communication method includes steps S101 to S102.
[0048] Step S101: When the second communication device receives the first optical communication signal sent by the first communication device, extract the first tone-top signal from the first optical communication signal, where the first optical communication signal is an optical modulation signal including at least a carrier signal and the first tone-top signal.
[0049] In this embodiment, taking the application of this communication method to the second communication device 201 as an example for illustration, and taking the first communication device as the first communication device 101 for illustration.
[0050] Exemplarily, the first communication device 101 loads the first device information into the carrier signal through the tone-top technology, and converts it into the corresponding first optical communication signal and sends it to the second communication device 201 connected by optical fiber network communication, so as to monitor whether the signal transmission of the first communication device 101 is abnormal through the second communication device 201.
[0051] When the second communication device 201 receives the first optical communication signal λ1 sent by the first communication device 101, the second communication device 201 extracts the first tone signal from the first optical communication signal λ1 through the second optical splitter 2016 and the second optoelectronic converter 2014. The first optical communication signal λ1 is an optical modulation signal including at least a carrier signal and a first tone signal, and the first tone signal is a signal carrying the first device information corresponding to the first communication device. The first device information includes at least one of the bit error rate, signal-to-noise ratio, received optical power, and eye diagram sampling data of the signal received by the receiving end of the first optical interface 1019 of the first device information.
[0052] Based on the first device information, it can be determined whether the relevant parameters of the transmitting end of the second optical interface 2019 of the second communication device 201 need to be adjusted, or whether the equalization parameters of the receiving end of the first optical interface 1019 of the first communication device 101 need to be adjusted.
[0053] Step S102: Adjust the amplification gain of the carrier signal according to the first tone signal so that the signal amplitude of the carrier signal meets a preset standard.
[0054] Adaptively adjust the amplification gain of the carrier signal of the first optical communication signal λ1 according to the signal parameters of the obtained first tone signal, so as to obtain a carrier signal with a signal amplitude meeting the preset standard, where the preset standard is that the output amplitude of the carrier signal is stable and the amplitude meets the preset value.
[0055] Please refer to Figure 4 , in some embodiments, step S102 includes steps S1021 to S1022.
[0056] Step S1021: Obtain the signal parameters of the first tone signal.
[0057] The signal parameters of the first tone signal include the signal length and the signal amplitude. By obtaining the specific signal parameters of the first tone signal, the amplification gain of the carrier signal of the first optical communication signal λ1 is adjusted according to the signal parameters, so as to obtain a carrier signal with a stable output amplitude and an amplitude meeting the preset value.
[0058] In some embodiments, the obtaining the signal parameters of the first tone signal includes:
[0059] Perform optoelectronic conversion on the first tone signal to obtain a corresponding first electrical signal;
[0060] Extract the signal parameters of the first electrical signal, where the signal parameters include the signal amplitude and the signal length.
[0061] Exemplarily, the first optical communication signal λ1 is split by the second optical splitter 2016, and a preset proportion of the first optical communication signal λ1 is output to the second optoelectronic converter 2014 for optoelectronic conversion, so as to convert a preset proportion of the first optical communication signal λ1 into a corresponding electrical signal, thereby identifying the signal parameters corresponding to the first tone signal in the first optical communication signal λ1.
[0062] For example, 90% of the first optical communication signal λ1 is converted into a corresponding electrical signal. Since the frequencies of the carrier signal and the first tone signal are different, the electrical signal parameters such as the signal amplitude and signal length corresponding to the electrical signal obtained after optoelectronic conversion are also different. Therefore, the second optoelectronic converter 2014 can identify the first electrical signal corresponding to the first tone signal in the first optical communication signal λ1 after optoelectronic conversion by identifying the intensity of the corresponding electrical signals generated by the carrier signal and the first tone signal after optoelectronic conversion, and obtain signal parameters such as the signal amplitude and signal length of the first electrical signal.
[0063] Step S1022: Adjust the amplification gain of the carrier signal according to the signal parameters.
[0064] The second optoelectronic converter 2014 outputs signal parameters such as the signal amplitude and signal length of the first electrical signal corresponding to the converted first tone signal to the second gain controller 2017. The second gain controller 2017 adaptively adjusts the amplification gain of the carrier signal of the first optical communication signal λ1 by the second optical signal amplifier 2018 according to the signal parameters of the first tone signal, so that the output amplitude of the obtained amplified carrier signal is more accurate.
[0065] In some embodiments, the adjusting the signal amplification gain of the carrier signal according to the signal parameters includes:
[0066] Adjust the amplification gain of the carrier signal according to the signal amplitude and the signal length, so that the signal amplitude of the carrier signal meets a preset standard.
[0067] The first optical communication signal λ1 passing through the second optical splitter 2016 is output to the second optical amplifier 2018. The second gain controller 2017 controls the amplification gain of the carrier signal of the first optical communication signal λ1 by the second optical amplifier 2018 according to signal parameters such as the signal length and signal amplitude of the obtained first electrical signal, so as to obtain a stable output carrier signal with an output amplitude within a preset amplitude range, thereby effectively reducing the influence of the first tone signal on the carrier signal after the first tone signal is loaded on the carrier signal.
[0068] Please refer to Figure 5 , Figure 5 which is a schematic flowchart of another communication method provided by an embodiment of the present invention.
[0069] The communication method further includes steps S201 to S205.
[0070] Step S201: When the second communication device receives the first optical communication signal sent by the first communication device, extract the first tone signal from the first optical communication signal, where the first optical communication signal is an optical modulation signal including at least a carrier signal and the first tone signal.
[0071] Figure 5 Step S201 in Figure 1 is the same as step S101 in
[0072] and will not be elaborated here.
[0073] Figure 5 Step S202 in Figure 1 is the same as step S102 in
[0074] and will not be elaborated here.
[0075] The second optoelectronic converter 2014 outputs the first electrical signal corresponding to the converted first tone signal to the second tone unit 2015 for signal demodulation in the second tone unit 2015, so as to obtain the first device information corresponding to the first communication device 101, where the first device information is used to evaluate the signal transmission stability between the first communication device 101 and the second communication device 201.
[0076] In some embodiments, the first device information includes at least one of the bit error rate, signal-to-noise ratio, received optical power, and eye diagram sampling data of the signal received by the receiving end of the first optical interface 1019 of the first communication device 101.
[0077] Step S204: Generate feedback information according to the first device information and send it to the first communication device, so that the first communication device adjusts the relevant parameters of the first optical interface of the first communication device.
[0078] Exemplarily, the second communication device 201 determines whether there is any abnormality in any one of the bit error rate, signal-to-noise ratio, received optical power, or eye diagram sampling data of the signal received by the receiving end of the first optical interface 1019 of the first communication device 101 according to the acquired first device information. When there is an abnormality in the first device information, the second communication device 201 generates feedback information based on the abnormal data and sends it to the first communication device 101, so that the first communication device 101 adjusts the relevant parameters of the first optical interface 1019 of the first communication device 101. For example, when the bit error rate is abnormal, the transmitted optical power of the transmitting end of the first optical interface 1019 of the first communication device 101 is adjusted. When the signal-to-noise ratio is abnormal, the dispersion parameter of the first optical interface 1019 of the first communication device 101 is adjusted.
[0079] Step S205: Receive the first parameter adjustment feedback of the first communication device for the first optical interface, and adjust the relevant parameters of the second optical interface of the second communication device according to the first parameter adjustment feedback.
[0080] After the parameter adjustment of the first optical interface 1019 of the first communication device 101 is completed, the optical communication information is sent to the second communication device 201 again through the transmitting end of the first optical interface 1019. If the second communication device 201 determines that the transmitting end of the first optical interface 1019 still needs to be adjusted according to the received signal, corresponding feedback information is generated again, and so on in a loop.
[0081] When the adjustment of the parameters of the first optical interface 1019 cannot improve the signal transmission stability between the first communication device 101 and the second communication device 102, the first communication device 101 generates corresponding first parameter adjustment feedback and sends it to the second communication device 201. The second communication device 201 then adjusts the receiving end equalization parameter of the second optical interface 2019 of the second communication device 201 according to the first parameter adjustment feedback.
[0082] For example, after the first communication device 101 adjusts the parameters of the transmitting end of the first optical interface 1019 multiple times, and the bit error rate and signal-to-noise ratio of the signal received by the receiving end of the second optical interface 2019 of the second communication device 201 still cannot reach the preset range, the first communication device 101 generates the first parameter adjustment feedback to the second communication device 201 to inform the second communication device 201 that the parameter adjustment of the first optical interface 1019 can no longer improve the signal transmission stability problem between the first communication device 101 and the second communication device 201, and the second communication device 201 needs to adjust the parameters of the receiving end of its own second optical interface 2019. Then the second communication device 201 adjusts the receiving end equalization parameter of the second optical interface 2019 according to the first parameter adjustment feedback.
[0083] In some embodiments, Figure 5Different from the communication method provided by the corresponding embodiment, the communication method further includes:
[0084] Loading the second device information onto the carrier signal to form a second optical communication signal, where the second device information is used to evaluate the signal transmission stability between the first communication device and the second communication device;
[0085] Sending the second optical communication signal to the first communication device to obtain a feedback signal in response to the second optical communication signal by the first communication device, and adjusting relevant parameters of the second optical interface of the second communication device according to the feedback signal.
[0086] Exemplarily, the second communication device 201 loads the second device information onto the carrier signal after gain adjustment to form a second optical communication signal λ2, where the second device information is used to evaluate the signal transmission stability between the first communication device 101 and the second communication device 201, and the second device information includes at least one of the bit error rate, signal-to-noise ratio, received optical power, and eye diagram sampling data of the signal received by the receiving end of the second optical communication interface 2019 of the second communication device 201.
[0087] The second communication device 201 sends the second optical communication signal λ2 to the first communication device 101, so that the first communication device 101 analyzes the corresponding second device information according to the second optical communication signal λ2. The first communication device 101 knows whether any one of the bit error rate, signal-to-noise ratio, received optical power, or eye diagram sampling data of the signal received by the receiving end of the second optical interface 2019 of the second communication device 201 is abnormal according to the obtained second device information. When the second device information is abnormal, the first communication device 101 generates a feedback signal according to the abnormal data and sends it to the second communication device 201. The second communication device 201 adjusts relevant parameters of the second communication device 201 according to the feedback signal. For example, when the bit error rate is abnormal, the transmitted optical power of the transmitting end of the second optical interface 2019 of the second communication device 201 is adjusted. When the signal-to-noise ratio is abnormal, the dispersion parameter of the second communication device 201 is adjusted.
[0088] In some embodiments, the communication method further includes:
[0089] Receiving the feedback on the adjustment of the second parameter of the second optical interface by the second communication device, so that the first communication device adjusts relevant parameters of the first optical interface according to the feedback on the adjustment of the second parameter.
[0090] Exemplarily, after the second communication device 201 finishes adjusting the parameters of the second optical interface 2019, the optical communication information is sent to the first communication device 101 again through the transmitting end of the second optical interface 2019. If the first communication device 101 determines that the transmitting end of the second optical interface 2019 still needs to be adjusted based on the received signal, corresponding feedback information is generated again, and so on in a loop.
[0091] When the adjustment of the parameters of the second optical interface 2019 cannot improve the signal transmission stability between the first communication device 101 and the second communication device 102, the second communication device 201 generates corresponding second parameter adjustment feedback and sends it to the first communication device 101. The first communication device 101 then adjusts the receive-end equalization parameters of the first optical interface 2019 of the first communication device 101 according to the second parameter adjustment feedback.
