    摘要： A communication system includes three or more nodes and a multi-core fiber having a plurality of cores, the multi-core fiber being used in at least a partial segment of the connection between the nodes is provided. One node of the nodes is connected to the multi-core fiber and includes a connector configured to add and drop a signal to and from an allocated core exclusively allocated from among the cores as a communication path between the one node and another node of the nodes and/or configured to relay a signal transmitted through another core of the cores allocated for communication between other nodes in the multi-core fiber connected to the one node, and a relative positional relationship between a connection position of the allocated core in which a signal is added or dropped in the connector and a connection position of another core in which a signal is relayed in the connector is the same for all of the nodes connected to the multi-core fiber.

    摘要： An output port switching unit that connects to a first optical transmission path, a second optical transmission path, and the connection information processor, and sets a destination of the first optical transmission path as the connection information processor in an initial state. A controller that transmits transmission mode information indicating a transmission mode identified based on connection information of the first optical transmission path acquired from an optical signal transmitted by an optical transceiver provided in an optical communicator that the connection information processor connects to the first optical transmission path, connection request data included in the optical signal and transmitted by the optical transceiver, and transmission path information of the second optical transmission path to the optical transceiver through the first optical transmission path. The output port switching unit performs switching processing of switching a destination of the first optical transmission path from the connection information processor to the second optical transmission path after the controller transmits the transmission mode information.
