Embodiment 1
[0033] The basic flow of the optical fiber connection relationship inspection method in the first embodiment of the present invention can be referred to figure 2 , the optical fiber connection relationship inspection method of the present embodiment mainly includes:
[0034] Step 101, shutting down the output ports of each optical signal processing single board in a network element device.
[0035] There is a switch in front of the output port of each optical signal processing board, and the switch can control the closing of the output port of each optical signal processing board. If the output port of the optical signal processing single board is opened, the received optical signal can be sent to its adjacent optical signal processing single board after corresponding processing.
[0036] Step 102, select an optical signal processing board, and guide the optical signal output by the auxiliary light source into the optical signal processing board.
[0037] The auxiliary ligh...

[0048] The basic flow of the optical fiber connection relationship inspection method in the second embodiment of the present invention can be referred to Figure 4 , this example combines image 3 The optical fiber connection schematic diagram of the network element equipment shown in this embodiment is illustrated by taking the case of finding the connection relationship of the multiplex optical fiber as an example. The method for checking the optical fiber connection relationship mainly includes:
[0049] Step 201, shut down image 3 For the output ports of each optical signal processing board in the shown network element equipment (that is, the output ports of U21, U22, U23, and U24), one optical signal processing board is selected arbitrarily, for example, the optical signal processing board U21 is selected.
[0050] Step 202, import the optical signal output by the auxiliary light source from the input port of the optical signal processing board to the selected optical s...

[0067] For ease of understanding, the method for checking the connection relationship of optical fibers provided by the present invention is described in detail below: In this embodiment, the connection relationship checking of single-wavelength optical fibers is taken as an example for illustration. see figure 1 , U3 is a single-wavelength signal processing board. The single-wavelength signal processing board U3 demultiplexes the received wavelength-division multiplexing signals, and outputs single-wavelength signals from its output ports. Each output port of U3 is connected to a Single-wavelength optical signal processing single board. see Figure 5 , is a flow chart of the third embodiment of the method for checking optical fiber connection relationship provided by the present invention, the method includes:
[0068] Step 301, shutting down the output ports of each optical signal processing single board in a network element device.
[0069] see figure 1, to turn off the...
