Abstract
The present disclosure relates to a technical field of optical communication, and more particularly to a device and method for matching optical fiber connections for ROADM service side, wherein the device comprises a reference control optical channel transmitter, a downlink WSS, a plurality of emitting ports, a reference control optical channel receiver, an uplink WSS and a plurality of receiving ports; the reference control optical channel transmitter emitting a reference control optical channel signal, and the downlink WSS emitting the reference control optical channel through the respective emitting ports in a polling manner; the reference control optical channel receiver receiving the reference control optical channel signal, and the uplink WSS selectively receiving the reference control optical channel over the plurality of receiving ports in the polling manner; wherein the reference control optical channel operating within an operating wavelength range of WSSs in the ROADM but outside a wavelength range of a service optical channel. By using WSS to control polling of the reference control optical channel among service side ports of ROADM, the present disclosure realizes an auto-routing matching of an optical fiber connection between different service side ports of ROADM and improves configuration efficiency, and at the same time, also realize to monitor performance of the optical fiber connection between service side ports of ROADMs in different directions and be a standby physical channel for chassis cascade.
