Abstract:Two novel optical add-drop multiplexer (OADM) with different self-healing functionalities for reliable wavelength-division-multiplexing networks are presented and demonstrated. Single or multiple failure-link traffics can be bi-directionally restored without the need for wavelength conversion or extra backup fiber links. To evaluate the performances of the proposed structures, a 77-channel CATV signal is experimentally transmitted with a favorable carrier-to-noise ratio (CNR), composite second-order (CSO) and composite triple beat (CTB) performances.
