PROBLEM TO BE SOLVED: To suppress an expanded matrix scale of a node optical switch and an increased number of wirings, and to secure a bypass route having a suppressed number of passing nodes.SOLUTION: An optical transmission system includes at least one ring network constituted by a plurality of nodes. Each node in the ring network includes an optical switch having a connection configuration in which a signal input to the node is permitted to be output to at least two directions, and is configured to allow the output of the optical switch to be input to another node included in the plurality of nodes. |
