More Information
Summary:The equipment has multiplexers (M1,M2) connected to respective portions of fiber optics that carry multiplexed signals in opposite directions. Signal protection units present a wavelength in one portion when an interruption of transmission of signals from a terminal is locally detected. The wavelength is transmitted to the multiplexer (M2) according to another wavelength so that the terminal transmits the signals. Independent claims are also included for the following: (a) a procedure of transmission of signals around a wavelength division multiplexing ring communication network (b) utilization of equipment of a equipment of a wavelength division multiplexing ring communication network and a procedure of transmission of signals around a wavelength division multiplexing ring communication network.
