摘要
A reconfigurable optical add/drop multiplexer and a reconfigurable optical add/drop multiplexing method are provided. The reconfigurable optical add/drop multiplexer comprises: an optical processing unit for receiving a first optical signal containing a plurality of optical channels, processing the first optical signal to generate a second optical signal which is a part of the first optical signal, and outputting the second optical signal; and a coherent detection unit for performing a coherent detection on the second optical signal so as to separate from the second optical signal an optical channel contained therein, and outputting the optical channel. With the reconfigurable optical add/drop multiplexer and the reconfigurable optical add/drop multiplexing method, any number of degrees can be supported, and adding/dropping of an optical channel with any wavelength and any bandwidth to/from any direction can be achieved, so that requirements of being colorless, directionless, contentionless and gridless can be satisfied.
