Abstract
A wavelength selective switch, including: an optical fiber array, an optical signal processing device and an output selection device. The optical fiber array includes multiple dual-core optical fibers arranged in parallel, one dual-core optical fiber being used for inputting two optical signals; the optical signal processing device is located at an output end of the optical fiber array and is used for splitting the two optical signals into sub-signals of different wavelengths and projecting the sub-signals of different wavelengths to different spectral band regions in the output selection device; and the output selection device is located at the rear end of the optical signal processing device, and is used for processing the sub-signals projected to the spectral band regions, so as to respectively perform output selection on the sub-signals split from two optical signals, thereby achieving a dual-switch function.
