  • Patent number: 6307652
    Abstract: An optical communication system (11) includes a plurality of nodes (16,17,18,19), each node connected in a first optical communication path (22) and a second optical communication path (23) extending parallel to the first optical communication path. The first optical communication path (22) is joined to each node by a first receiver (30) and first transmitter (31), while the second optical communication path (23) is joined to each node by a second receiver (32) and second transmitter (33). One of the nodes comprises a control unit node (19) having a control unit (37) associated therewith. The other nodes of the communication system comprise data unit nodes, each having a data unit (36) associated therewith. The communication system (11) normally operates with the control unit (37) in an open mode of operation in which data is not transferred across the node. Thus, in normal operation, the communication system (11) operates in an open ring configuration.
