ABSTRACT:
An optical switch for switching wavelength multiplexed optical signals between N input links and M output links is disclosed. The optical switch contains a first plurality of input terminals, optical splitters, tunable optical wavelength filters, optical switching elements, transmitters and optical couplers. In addition, the optical switch also contains a second plurality of output terminals, optical couplers, receivers, and optical splitters. Controllers control the first tunable wavelength optical filters, transmitters, and the receivers, selecting wavelengths for each from among 2n-1 different wavelengths so as to prevent two identical wavelengths from occurring simultaneously in any one of the input links and output links.
