摘要： A state estimating device includes a pre-processing unit and an estimating unit. The pre-processing unit acquires data representing at one or more of a phase of a signal transmitted from a transmission unit of a transmission device and received at a reception unit of another transmission device via a transmission path, a reception strength, a reception quality, a voltage after conversion into an electric signal, and a signal processing parameter used in reception processing, and processes the acquired data into feature data to be used for state estimation. The estimating unit estimates a state of the transmission path, an abnormal state of the transmission unit, or an abnormal state of the reception unit, on the basis of the feature data.

摘要： A communication system includes three or more nodes and a multi-core fiber having a plurality of cores and being used in at least a partial segment of the connection between the nodes. 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 for communication between the one node and another node of the nodes and/or configured to relay a signal transmitted through another core allocated to communication between the other nodes in multi-core fibers connected to the one node.

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.
