FIG. 1 is a schematic flowchart of some embodiments of the disclosed top modulation signal transmission control method.

In step 110, the first multi-channel optical module and the second multi-channel optical module interact to determine the first channel for transmitting the top adjustment signal.

In some embodiments, the first multi-channel optical module is an optical module located at the remote end, and the second multi-channel optical module is an optical module located at the central office.

The first channel is the main channel that transmits the top tuning signal.

In step 120, the first multi-channel optical module transmits the optical module information to the second multi-channel optical module in the form of a top-adjusting signal through the first channel.

In some embodiments, the optical module information includes OAM (Operation Administration and Maintenance, operation and maintenance management) information.

In some embodiments, the remote optical module sends the OAM information to the driver or modulator in a framed manner through an MCU (Microcontroller Unit, micro control unit), superimposes it on the main road data service in the form of a low-speed analog signal, and then converts it. The optical signal is converted into an optical signal, and the optical signal is sent to the optical module at the central office. The optical module at the central office converts the optical signal into an electrical signal, and then obtains the OAM signal after processing by one or more circuits of amplification, filtering, and amplitude limiting, and finally returns to the MCU to parse the original data. After receiving the instruction of reading the information of the remote optical module sent by the host device, the central office optical module can send the information of the remote optical module to the host device, so that the host device can complete the central office optical module and the remote optical module. Data collection and monitoring of end optical modules.

In this embodiment, through the interaction of the multi-channel optical modules at both ends, one channel is determined as the main channel for transmitting the top modulation signal, and then the optical module information is transmitted to the opposite end through the single channel, which can ensure that the main channel data is not affected. At the same time of business, the interaction of optical module information is realized.

FIG. 2 is a schematic flowchart of other embodiments of the disclosed top modulation signal transmission control method.

In step 210, the first multi-channel optical module transmits the service signal carrying the preconfigured top-adjustment signal to the second multi-channel optical module through multiple channels.

In some embodiments, as shown in FIG. 3 , each sub-channel inside the multi-channel optical module is equipped with a set of sending and receiving processing circuits for top-adjustment signals, ie, top-adjustment circuits, which are centrally controlled and scheduled by the MCU. Before transmitting the optical module information, it is necessary to complete the pre-configuration of the top tuning channel, select a single sub-channel to transmit the optical module information, and close the top tuning circuit of other channels.

In this step, as shown in Figure 4, the remote optical module turns on the top adjustment circuit of each channel, generates a top adjustment signal with a certain frame format for handshake, and transmits it to the central office optical fiber through each channel together with the service data signal. module.

In some embodiments, the optical module at the central office determines the bit error rate of each channel according to the service signal sent by each channel, and uses the channel with the smallest bit error rate as the first channel, that is, as the main channel for transmitting the top modulation signal .

For example, the optical module is equipped with a PRBS (Pseudo-Random Binary Sequence, pseudo-random binary sequence) transmission and detection functional unit. The data part of the remote optical module transmits PRBS signals of the specified code type (such as PRBS7/PRBS15/PRBS23/PRBS31, etc.), and the central optical module receives and detects these PRBS signals, and calculates the bit error rate of each channel separately. Among them, the PRBS code patterns set by the optical modules at both ends must be consistent to ensure the accuracy of the bit error rate calculation. The single-channel bit error rate is equal to the ratio of the number of error bits received by the channel to the total number of received data bits. For systems with 0 bit error rate, the fiber link loss can be increased. The optical module at the central office finds a channel with the smallest bit error rate, and uses this channel as the channel with the best performance under the interference of the top-adjusted signal, and it is also the most suitable path for receiving information from the remote optical module.

In some embodiments, the central office optical module sends the first channel information to the remote optical module through the first channel, and turns off the top adjustment circuits of other channels except the first channel.

In step 230, the first multi-channel optical module disables the top adjustment function of other channels except the first channel according to the first channel information, and uses the first channel as the main channel for transmitting the top adjustment signal.

When the performance of the main adjustment top channel is degraded, causing the central office optical module to fail to receive the information sent by the remote optical module, the selection is based on the channel bit error rate. The channel with the next best performance is selected as the second channel, that is, the backup channel.
