Problems solved by technology

[0004] In the existing technology, each network element or single board needs to be externally connected or built-in OSA instrument, and the OSA function is used to determine whether the optical fiber connection is correct. When a new optical fiber connection is introduced, the detection result may be incorrect due to the wrong optical fiber connection, and the external or The cost of the built-in OSA unit is relatively high, and the optical signal needs to be sent from the upstream NE to the local NE for detection. Please refer to figure 1 , if the upstream and downstream connections of U1 and U2 in the figure are wrong, the actual optical signal transmission will become: the optical signal sent by the light source is sent to U2 first, and then sent from U2 to U1, and the optical fiber connection relationship is checked by the above-mentioned prior art method , it can still be detected that both U1 and U2 receive optical signals with wavelengths of λ1 ~ λ4, so that the connection relationship between U1 and U2 is judged to be correct, and the upstream and downstream connection relationship between U1 and U2 as shown in the figure cannot be found to be wrong.

Abstract

The embodiment of the invention provides an optical fiber connection relation checking method and an optical fiber connection relation checking device. In the method, light signals output by a secondary light source are controlled to be led into a selected light signal processing single board, an output port of the selected light signal processing single board is opened, and that whether other light signal processing single boards detect the light signals output by the selected light signal processing single board is judged, so that downstream light signal processing single boards adjacent tothe selected light signal processing single board are judged and the upstream and downstream connection relation between the light signal processing single boards is discovered by executing the stepsthrough the light signal processing single boards. Through the method and the device, the connection relation is checked without externally connected OSA instrument or built-in OSA unit, a new optical fiber connection error risk due to the introduction of new optical fiber connection is avoided, and the cost of the external OSA instrument or the built-in OSA unit cannot be increased.
