Abstract

A ring network communication structure for communication comprising a nodes connected to each other in pairs and each connection comprising pairs of first and second optical carriers. Transmission occurs on the ring according to a WDM scheme, by utilizing a first wavelength for communication in one direction on the first carrier of the pair, and a second wavelength for communication in the opposite direction on the other optical carrier. In the presence of a failure on one of the connections, the nodes adjacent to the failed connection are reconfigured to provide continuation of communication on the alternative path provided by the ring, by utilizing the first wavelength for communication on the second carrier and the second wavelength for communication on the first carrier.
The ring structure is suitable for application to SDH
optical fibre ring networks.
