Description

technical field [0001] The present application relates to the technical field of communication optical path testing, in particular to a WDM wavelength channel identification method, device, equipment and readable storage medium. Background technique [0002] The 5G fronthaul network uses three optical wavelength division multiplexing devices: LWDM (LAN WDM, fine wavelength division multiplexing), MWDM (Dense WDM, dense wavelength division multiplexing), and CWDM (Coarse WDM, sparse wavelength division multiplexing), which can realize The function of transmitting multiple optical wavelength signals in the same optical fiber reduces the cost of network construction. Among them, for the test of WDM (Wavelength Division Multiplexing, wavelength division multiplexing) devices, no matter which method is used, a two-dimensional data table of a channel will eventually be obtained, that is, insertion loss-wavelength data, also known as the insertion loss spectrum of the wavelength ch...
