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 1X and inputted in circuit direction, switch multi-wavelength optical signals among direction 1X 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 1X 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.
