Two variants of a fiber-optical crossbar switch based on the magnetooptical spatial light modulator (MOSLM) have been developed for the purpose of connecting N inputs with M outputs with the arbitrary reconfiguration network. The 2D MOSLM uses Bi-substituted iron garnet film and consists of 128 x 128 elements. In the first variant the MOSLM is used as a multichannel array of light-beam shutters with vector-matrix multiplicator architecture for a small (less than 10) number of optical channels. In the second variant, the MOSLM is used as a multichannel light deflector for a high (10 and more) number of optical channels and appeared to be more effective. Experiments show that switching times are in the range from 0.1 to 10 microsec, while the best results were obtained in the case of films with pronounced orthorhombic anisotropy.
