    摘要： Provided is a wavelength selective switch. The wavelength selective switch includes a first wavelength division multiplexer, an M number of optical switches, an (M+N−1) number of optical combiners, and a second wavelength division multiplexer. The first wavelength division multiplexer receives optical signals of an M number of wavelength channels to divide the received optical signals according to each channel, thereby outputting the divided optical signals. The M number of optical switches changes a path of on an optical signal outputted by an M number of wavelength channels from the first wavelength division multiplexer into one of an N number of output ports. The (M+N−1) number of optical combiners is respectively connected to the N number of output ports of the optical switches. The (M+N−1) number of optical combiners couple the N number of inputted optical signals to one output port. The second wavelength division multiplexer has an (M+N−1) number of input ports and an N number of output ports. The (M+N−1) number of output signals of the optical combiners is connected to the input ports, respectively, and the inputted signals are multiplexed to output the multiplexed signals from any of the N number of output ports.
