ABSTRACT:
In an optical transmission system including a trunk LAN having duplex optical transmission lines, and branch LANs connected with the trunk LAN through nodes, an optical signal on the optical transmission line of the trunk LAN is input to a node including an optical switch, an optical transmitting and receiving circuit, a serial-parallel converter, an internal bus, and a LAN interface. The optical signal input to the node is converted to an electric signal (serial date) by the optical transmitting and receiving circuit through the optical switch, and is converted to parallel data by the serial-parallel converter. Thereafter, the parallel data is output onto the internal bus. The LAN interface peforms an operation for outputting the parallel data onto the internal bus to the branch LANs. Data on the branch LAN is output to the optical transmission line by the operation opposite to that described above. The node can include a signal optical transmitting and receiving circuit. A self return mode is set by the LAN interface, so that the presence/absence of malfunction of the node can be self-checked.
