Abstract:
1. An optical communicating apparatus, comprising: a two-core optical transmission path by which the optical communicating apparatus is optically coupled to another optical communicating apparatus: a one-core optical transmission path that passes a first optical signal transmitted from an optical transmitter/receiver performing one-core bilateral communication and a second optical signal transmitted to the optical transmitter/receiver in an opposite direction; a first coupler that inserts the first optical signal transmitted from the optical transmitter/receiver through the one-core optical transmission path, into a first core of the two-core optical transmission path to the other optical communicating apparatus; and a second coupler that branches the second optical signal transmitted from a second core of the two-core optical transmission path which is optically coupled to the other optical communication apparatus, to the optical transmitter/receiver through the one-core optical transmission path, wherein the two-core optical transmission path is an optical transmission path of a Synchronous Optical NETwork/Synchronous Digital Hierarchy-scheme network.
