摘要 |
It is difficult to increase the number of inputs and outputs of an optical switch supporting CDC functions, therefore, an optical switch according to an exemplary aspect of the present invention includes a unit optical switch inputting n optical signals and outputting n optical signals; an optical splitter inputting a single optical signal, splitting the single optical signal into k optical signals, and outputting the k optical signals; and an optical selector inputting m optical signals and outputting a single optical signal, wherein the optical splitter includes m×n pieces, the unit optical switch includes m×k pieces, the optical selector includes n×k pieces, (k×(m×n)) outputs of the optical splitter correspond to (n×(m×k)) inputs of the unit optical switch, (n×(m×k)) outputs of the unit optical switch correspond to (m×(n×k)) inputs of the optical selector, and (n×m) optical signals inputted into the optical splitter are output through the (m×k) unit optical switch from the optical selector as (n×k) optical signals. |
