Detection unit, optical switch unit, related equipment and port calibration method

Abstract

The embodiment of the invention provides a detection unit, an optical switch unit, related equipment and a port calibration method. The detection unit, the optical switch unit, the related equipment and the port calibration method are used for automatically acquiring a connection relation between a PON port and an input port. The detection unit provided by the embodiment of the invention comprises a wavelength division demultiplexer used for splitting an input optical signal of the detection unit to obtain an uplink service signal of a communication band and a detection signal of a non-communication band, and the input optical signal comes from an internal port connected with the detection unit; the first detection module is used for detecting a detection signal; the second detection module is used for detecting an uplink service signal; the processing module is used for determining the target configuration of the target mark port, and determining the internal port currently connected with the detection unit as a target internal port under the condition that the uplink service signal has the target configuration, the target internal port corresponding to a target input port connected with the target mark port, and the target internal port corresponding to the target input port corresponding to the target mark port; the target mark port comprises a plurality of mark ports of the PON single board, and different mark ports are used for connecting different ODNs.
