摘要： A reconfigurable optical add and drop multiplexer (ROADM) system is provided. The ROADM system may include a switching system which includes at least one first WSS optically coupled to a tapping coupler and configured to receive an input optical signal from a first circulator, transmit a drop optical signal to a demultiplexer to drop one or more first wavelength channels, and output a through optical signal. The switching system may also include at least one second WSS optically coupled to the at least one first WSS and a multiplexer and configured to receive an add optical signal to add one or more second wavelength channels, receive the through optical signal, and output an output optical signal to a second circulator, and at least one OCM configured to monitor the input optical signal and the output optical signal.
