Abstract
An apparatus includes a plurality of demultiplexing modules, a plurality of multiplexing modules, and a plurality of N×N switching modules. Each demultiplexing module is connected to P N×N switching modules through optical fibers. Each multiplexing module is connected to P N×N switching modules through optical fibers. Demultiplexing modules and multiplexing modules are connected to same N×N switching modules. At least one N×N switching module connected to a target demultiplexing module has a function of switching optical signals of a plurality of wavelengths for the target demultiplexing module. A quantity of wavelengths of optical signals received by each N×N switching module connected to the target demultiplexing module from the target demultiplexing module is less than a target value, and the target value is a quantity of wavelengths of optical signals received by the target demultiplexing module.
