摘要：
A combined wavelength router and switch apparatus for use in an optical communication system is disclosed. The apparatus includes arrays of optical signal demultiplexers, wavelength division switches, space division switches and multiplexers, arranged in a manner that can increase the connectivity of an optical system using wavelength division multiplexed (WDM) signals. In several embodiments, time-multiplexed wavelength division switches and time-multiplexed space division switches may be used to increase further the degree of connectivity of the system or to reduce the number of wavelength division switches and space division switches required. Additional arrays of wavelength division switches or time-multiplexed wavelength division switches may be included to allow carrier frequencies to be shifted to meet the channel ordering requirements of the optical system.
摘要（中）：
在光通信系统中使用的组合波长路由器和交换机设备是游离缺失盘。 该装置包括光信号解复用器，波长分割开关，空分开关和多路复用器的阵列，以这样的方式布置确实可以增加使用波分复用（WDM）信号的光学系统的连通性。 在几个实施方案中，时间复用的波分复用开关和时间复用的空分开关可以被用来进一步增加系统的连通性的程度或以减少所需的波分开关和空分开关的数量。 可以包括波分复用开关或时间复用的波分复用开关的附加的阵列，以允许载波频率被移位，以满足信道订购的光学系统的要求。
