Problems solved by technology
When the ROADM dimension is high, there will be a large number of internal optical fibers connected manually, but it is impossible to verify whether the actual optical fiber connection is correct; in addition, the optical fiber connection relationship can only be manually entered into the network management system by the user, and the entered connection cannot be guaranteed. Consistency between the fiber state and the actual fiber connection state

Description
technical field [0001] The invention relates to the technical field of optical transmission, in particular to a detection system and method for optical fiber connection status, and ROADM equipment. Background technique [0002] ROADM (Reconfigurable Optical Add-Drop Multiplexer, Reconfigurable Add-Drop Multiplexer) is a node device of an optical fiber communication network. Its basic function is to complete the add and drop of selected wavelengths in real time through remote configuration, which can improve WDM (Wavelength Division Multiplexing, wavelength division multiplexing) the flexibility of the network to schedule wavelengths. [0003] At present, the ROADM in an actual network is mainly composed of a WSS (Wavelength Selective Switch, wavelength selective switch) and an optical combiner / demultiplexer connected through an optical fiber. For an N-dimensional ROADM, 2×N 2 interconnected by an internal optical fiber. When the ROADM dimension is high, there will be a la...
