ABSTRACT:
In an optical communication network in which a plural number of nodes are connected to each bidirectional broadcasting bus, and a node communicates with another using the packets, or an optical communication network in which a plural number of nodes are connected to a bidirectional broadcasting bus, and a node communicates with another using the packets, each node comprises carrier sensing means for sensing a carrier on the broadcasting bus, and jamming detecting means for detecting a jamming state of received signals.
