Abstract

See full text

Disclosed are a reconfigurable optical add-drop multiplexer, and an optical signal processing method. The reconfigurable optical add-drop multiplexer includes: at least one optical cross-connect device and at least two optical signal processing devices. Each optical signal processing device includes a wavelength-selective switch and a filter. The wavelength-selective switch is configured to perform wavelength-based allocation on inputted dense wavelength division multiplexing optical signals and input the dense wavelength division multiplexing optical signals into the filter. The filter is configured to separate optical signals outputted by the wavelength-selective switch into single-channel optical signals, and multiplex a plurality of single-channel optical signals outputted by the optical cross-connect device and input the multiplexed single-channel optical signals into the wavelength-selective switch. The wavelength-selective switch is configured to perform wavelength combination on the optical signals outputted by the filter and output the optical signals. The optical cross-connect device includes N upper ports and N lower ports.
