Abstract: Aspects of the present disclosure describe systems, structures and methods providing fully reconfigurable optical add-drop multiplexing (ROADM) that provide redundancy protection against any two (2) simultaneous wavelength selective switch (WSS) failures with only four 2x1 WSS structures for both Eastbound and Westbound traffic, while not requiring bidirectional operation of the WSS structures.

Abstract translation: 本公开的各方面描述了提供完全可重新配置的光分插复用（ROADM）的系统，结构和方法，其仅针对任何两（2）个同时波长选择开关（WSS）故障提供冗余保护，而仅 4个2x1 WSS结构用于东向和西向流量，同时不需要双向操作WSS结构。
