Abstract

The embodiment of the invention provides a colorless reconfigurable optical add-drop multiplexer and an optical signal receiving method. The optical add-drop multiplexer comprises a convergence WSS and a cascading coupling optical splitter, wherein an input port of the convergence WSS is connected with an input port of the cascading coupling optical splitter. The convergence WSS is used for receiving optical signals, which have different wavelengths and are transmitted by WSSs connected with a plurality of output ports in different directions, through a plurality of output ports, and enabling the received optical signals to be transmitted to the input port. The cascading coupling optical splitter is used for distributing the optical signals received by the input port to an output port connected with receiving equipment according to a preset power distribution rule. The optical add-drop multiplexer simplifies the deployment mode, and improves the equipment reliability. The invention relates to the technical field of communication.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a colorless reconfigurable optical add-drop multiplexer and an optical signal receiving method. Background technique [0002] In recent years, the explosive growth of bandwidth demand has brought enormous pressure to optical transmission networks, requiring the adoption of new optical communication modulation formats to increase transmission rates. At the cross node, both optical cross and electrical cross are widely used to improve the networking and flexible scheduling capabilities of the optical transmission network. The electrical crossover has the function of optical signal regeneration, but the capacity of the electrical crossover is relatively small and the energy consumption is high. The optical crossover (reconfigurable optical adddrop multiplexer, Reconfigurable optical adddrop multiplexer (ROADM)) architecture is suitable for the scheduling of large-grained ser...
