| 英文摘要 | The present invention aims at providing an optical switch network of lower loss, lower cost, downsized and superior expandability. To this end, one configuration of the optical switch network according to the present invention comprises a plurality of input ports, a plurality of output ports, a plurality of wavelength converting means provided corresponding to the plurality of input ports, respectively, for each converting a wavelength of light input from each of the input ports, and selecting means for outputting output lights from the plurality of wavelength converting means to particular ports of the output ports, respectively, corresponding to the wavelengths of the output lights. The optical switch network having such a configuration is free of provision of optical branching/coupling devices, therefore it is possible to achieve lower loss, downsized and superior expandability, as compared with conventional distributing and selecting type optical switch networks. According to another configuration of the optical switch network of the present invention, optical switching means for switching directional paths are arranged upstream and downstream of optical branching/coupling means, respectively, thereby enabling a smaller number of distributions at each optical branching/coupling means, to thereby achieve reduction of loss in the optical SW network. |
