RECONFIGURABLE OPTICAL ADD/DROP MULTIPLEXER

WIPO Patent Application WO/2017/190331

A1

A reconfigurable optical add/drop multiplexer, relating to the technical field of optical communications. The reconfigurable optical add/drop multiplexer comprises: an input component (101), a first wavelength dispersion component (102), a first redirection component (103), a first switch array (104) comprising (M + P) lines of switch units, a second switch array (105), a third switch array (106) and an output component (107). After (M + P) input beams input from the input component (101) are dispersed by the first wavelength dispersion component (102), M sub-beams of the input beams and P sub-beams of the input beams are obtained, and some sub-beams of the M sub-beams are respectively routed to N output ports via the first, second and third switch arrays (104, 105, 106). Some sub-beams are respectively routed to Q output ports via the first, second and third switch arrays (104, 105, 106). The P sub-beams of the input beams are respectively routed to N output ports via the first, second and third switch arrays (104, 105, 106). The reconfigurable optical add/drop multiplexer is applied to the process of optical communications.
