The optical transmission devices in the two communication devices are connected through an optical fiber link to realize the communication between the two communication devices. At present, the optical transmission device in the communication equipment can monitor whether there is an abnormality in its own working state, and issue an alarm when an abnormality occurs. However, if in the process of allocating or adjusting the resources of the optical network system, for example, the optical transmission device is connected to the wrong fiber, the current optical transmission device cannot perceive which optical transmission device is connected to the other end of the optical fiber link, so It is difficult for operation and maintenance personnel to locate the root cause of the error, which makes it difficult to manage the optical network system, resulting in low efficiency in resource adjustment of the optical network system. Among them, the fiber connection error of the optical transmission device means that the optical transmission device and another optical transmission device that should have established a communication connection relationship are not connected through an optical fiber link, resulting in the inability to communicate between the two optical transmission devices , or, the optical transmission device is connected through an optical fiber link to another optical transmission device that should not have established a communication connection relationship, resulting in unreasonable or illegal communication between the two optical transmission devices, or, A one-way communication connection relationship should be established between the optical transmission device and another optical transmission device in the direction from the optical transmission device to the other optical transmission device.

After the optical transmission device in the communication device on the receiving side receives the message, the receiving side The communication device can then determine that there is a communication connection relationship between the optical transmission device receiving the message and the optical transmission device indicated by the identifier carried in the message in the transmission direction of the message. In the embodiment of the present application, the communication device can clarify the communication connection relationship between its own optical transmission device and other optical transmission devices in a specific direction, so that the operation and maintenance personnel can know the fiber connection relationship between the optical transmission devices in the optical network system , helping to improve the resource allocation and adjustment efficiency of the optical network system.

On this basis, after receiving the message carrying the identification of the optical transmission device, the communication device on the receiving side may also respond to the message by sending a message including the identification of the optical transmission device that received the message through the optical transmission device that received the message. and another message of the identification of the optical transmission device carried in the message, used to determine the transmission direction of the message between the optical transmission device that received the message and the optical transmission device indicated by the identification carried in the message Whether there is a communication connection relationship in the opposite direction. When the communication device on the sending side receives the other message, the communication device on the sending side can determine according to the other message that the two optical transmission devices respectively indicated by the two identifiers carried in the other message have a two-way communication connection relationship .

The auxiliary channel modulation unit is used to modulate non-service signals such as management information, control information, and physical characteristic parameters other than service signals. Correspondingly, the auxiliary channel demodulation unit is used to demodulate non-service signals. Based on the auxiliary channel modulation unit in the first optical transmission device 011 and the auxiliary channel demodulation unit in the second optical transmission device 021, an auxiliary channel can be implemented for the first optical transmission device 011 to transmit non- business signal. Similarly, based on the auxiliary channel modulation unit in the second optical transmission device 021 and the auxiliary channel demodulation unit in the first optical transmission device 011, another auxiliary channel can be realized for the second optical transmission device 021 to transmit Device 011 transmits non-traffic signals.

Optionally, the auxiliary channel between two optical transmission devices is implemented based on an optical fiber link connecting the two optical transmission devices. For example, in the optical network system shown in FIG. 1 , the auxiliary channel between the first optical transmission device 011 and the second optical transmission device 012 is implemented based on the optical fiber link 03 . That is, the auxiliary channel and the traffic channel may share the same physical link.

For example, the auxiliary channel modulation unit may use frame insertion technology to insert non-service signals into idle frame bytes of service signals for transmission. Correspondingly, the auxiliary channel demodulation unit extracts and demodulates corresponding bytes in the received signal to obtain a non-service signal. In this implementation manner, non-service signals and service signals do not interfere with each other during transmission. Alternatively, the auxiliary channel modulation unit may insert the non-service signal into the reserved field of the training sequence frame by using the frame insertion technology for transmission. Correspondingly, the auxiliary channel demodulation unit demodulates the reserved field of the received training sequence frame to obtain the non-traffic signal. Wherein, the training sequence frame is usually transmitted before the transmission of the service signal.

Optionally, the auxiliary channel modulation/demodulation unit may be an independent modulation/demodulation unit, or may be integrated with the modulation/demodulation unit corresponding to the service signal, which is not limited in this embodiment of the present application.
