Therefore, the connection relation between the second optical port of the second communication device and the fiber core of the optical cable is automatically identified.
Fig. 2 shows the traffic pulse signals λ 1a λ 1c, the first identity pulse signals λ 2a λ 2c and the second identity pulse signals λ 2d λ 2 f. Here, in the notation of these signals, "λ 1" denotes a first wavelength, "λ 2" denotes a second wavelength, and the letters following "λ 1" and "λ 2" denote different identity pulse signals, i.e. indicate that these identity pulse signals carry identification information of different device optical ports (first optical port or second optical port). The following describes a process of identifying a connection relationship between the first optical port and the fiber core of the optical cable and a connection relationship between the second optical port and the fiber core of the optical cable, taking the service pulse signal λ 1a, the first identity pulse signal λ 2a, and the second identity pulse signal λ 2d as an example.
For example, as shown in fig. 2, the first communication device 110 sends out a service pulse signal λ 1a and a first identity pulse signal λ 2a through the first optical port 111; after receiving the service pulse signal λ 1a and the first identity pulse signal λ 2a, the first optical demultiplexer 120 forwards the service pulse signal λ 1a to the fiber core 171 of the optical cable 170, and forwards the first identity pulse signal λ 2a to the first optical code identification device 130; the first optical code recognition device 130 reads the identification information of the first optical port 111 from the first identity pulse signal λ 2a, and transmits the identification information of the first optical port and the code of the first terminal 121 of the first optical demultiplexer 120 to the optical cable management unit 140; the optical cable management unit 140 identifies the connection relationship between the first optical port 111 and the core 171 of the optical cable based on the identification information of the first optical port 111, the code of the first terminal 121 of the first optical demultiplexer 120, and the pre-stored code of the core 171 of the optical cable 170 corresponding to the first optical demultiplexer 120.
Next, the second optical demultiplexer 220 forwards the traffic pulse signal λ 1a to the second optical port 211 of the second communication device 210 after receiving the traffic pulse signal λ 1a from the fiber core 171 of the optical cable 170; the second communication device 210 receives the service pulse signal λ 1a through the second optical port 211 and sends out a second identity pulse signal λ 2d with a second wavelength through the second optical port 211, where the second identity pulse signal λ 2d carries identification information of the second optical port 211; the second optical demultiplexer 220 forwards the second identity pulse signal λ 2d to the second optical code identification device 230 after receiving the second identity pulse signal λ 2d from the second optical port 211; the second optical code identification device 230 reads the identification information of the second optical port 211 from the second identity pulse signal λ 2d, and transmits the identification information of the second optical port and the pre-stored code of the fourth terminal 224 of the second optical demultiplexer 220 to the optical cable management unit 140; the optical cable management unit 140 identifies the connection relationship between the second optical port 211 and the core 171 of the optical cable according to the identification information of the second optical port 211, the code of the fourth terminal 224 of the second optical demultiplexer 220, and the pre-stored code of the core 171 of the optical cable 170 corresponding to the second optical demultiplexer 220.
Therefore, the automatic identification of the connection relation between the first optical port and the optical cable fiber core and the connection relation between the second optical port and the optical cable fiber core is realized. The system does not need to manually input massive and sometimes-changed resource management system information, so that the actual situation of the network topology can be accurately mastered in real time, and service opening and network maintenance are guaranteed.

The first device network manager 150 is configured to send the device information of the first communication device 110 and the identification information of the first optical port 111 to the optical cable management unit. For example, the device information of the first communication device 110 may include: the device name, the board number, the port number, and the like of the first communication device. Thus, when the optical cable management unit identifies the connection relationship between the first optical port and the fiber core of the optical cable, it can identify which first optical port of which first communication device is connected to which fiber core of the optical cable.
In some embodiments, as shown in fig. 2, the system may further include a second device network manager 250. The second device network manager 250 is configured to send the device information of the second communication device 210 and the identification information of the second optical port 211 to the optical cable management unit 140.
