AI summary
The disclosure relates to the technical field of optical fibers, and particularly relates to an optical fiber detection method, a reconfigurable optical add-drop multiplexer (ROADM) system, a server, and a storage medium. The optical fiber detection method is applied to a network management server of the ROADM system. The method includes: sequentially turning on one optical fiber according to a preset order; controlling a downlink optical amplifier corresponding to the optical fiber to provide an optical signal; obtaining first optical power output by the downlink optical amplifier corresponding to the optical fiber and second optical power input to an uplink optical amplifier corresponding to the optical fiber; and obtaining a connection state of the optical fiber based on a pre-stored first insertion loss value of a downlink wavelength selective switch (WSS) corresponding to the optical fiber, a pre-stored second insertion loss value of an uplink WSS corresponding to the optical fiber, the first optical power, and the second optical power. In an entire testing process, corresponding optical fibers only need to be sequentially turned on according to the preset order, such that a lot of manpower, material resources and time cost are reduced, interference of human factors in test results is basically avoided, and reliability is greatly improved.
