Abstract

An optical communication network includes a plurality of nodes and optical fibers for interconnecting the nodes whereby an optical signal may be transmitted from a source node to a destination node which may be determined selectively. Each node includes input channels, output channels and a connection control device for controlling the connection between the input and output channels. Terminal devices are provided to be in operative association with selected nodes. Thus, the present invention provides a high speed network having high reliability. The present network is easy to expand and its reliability increases as it is expanded.
