    • A reconfigurable optical add-drop multiplexer (10) comprising an input (20), an output (22), drop outputs (30), add inputs (22), a demultiplexer (18), a cross-connect element (12), a drop element (34) and an add element (26). The cross-connect element (12) comprises cross-connect outputs (36), a by-pass output (38), and optical switches (14) connected together as a first switch array. The drop element (34) comprises optical switches (14) connected together as a second switch array. The add element (26) comprises optical switches (14) connected together as a third switch array. Each optical switch (14) comprises a first input (13), a second input (15), a first output (17) and a second output (19). Each optical switch is arranged to deliver a first optical signal received at the first input to the first output. Each optical switch (14) is arranged to receive a respective control signal arranged to cause the optical switch to route a second optical signal received at its second input to a selected one of its first output and its second output.
    • 一种可重新配置的光分插复用器(10),包括输入(20),输出(22),输出输出(30),加法输入(22),解复用器(18),交叉连接元件(12) 下降元件(34)和添加元件(26)。 交叉连接元件(12)包括作为第一开关阵列连接在一起的交叉连接输出(36),旁路输出(38)和光开关(14)。 液滴元件(34)包括作为第二开关阵列连接在一起的光开关(14)。 添加元件(26)包括作为第三开关阵列连接在一起的光开关(14)。 每个光开关(14)包括第一输入(13),第二输入(15),第一输出(17)和第二输出(19)。 每个光开关被布置成将在第一输入处接收的第一光信号传送到第一输出端。 每个光开关(14)被布置成接收相应的控制信号,该控制信号被布置成使得光开关将在其第二输入处接收到的第二光信号路由到其第一输出及其第二输出中的所选择的一个。
