RECONFIGURABLE OPTICAL ADD/DROP MULTIPLEXING DEVICE FOR ENABLING TOTALLY INRESISTANT COLORLESS

摘要

This invention provides a reconfigurable optical add/drop multiplexing device for enabling totally inresistant colorless. A dropping unit is configured to separate multi-wavelength optical signals which are among direction 1~X and inputted in circuit direction, switch multi-wavelength optical signals among direction 1~X to any corresponding output port through multiple N×N optical switches, and send optical signals to corresponding Receiver after combining the received optical signals by corresponding K×1 coupler/optical switch; an adding unit is configured to broadcast optical signals sent by Transmitter to multiple N×N optical switches through N 1×K couplers/ optical switches, switch optical signals to any corresponding output port by each optical switch, and output the corresponding optical signals in direction 1~X to circuit direction after optical signals are implemented with optical multiplexing. X is an integer greater than or equal to 2; K and N are integers. This invention can enable the totally inresistant colorless in adding/dropping units.
