Optical clock signal distribution system for WDM Networks

摘要

A system for controlling the clock synchronization between optical transmission devices constituting an optical communication network is disclosed. An optical clock generating means for converting a clock signal of a PRC (primary reference clock) level into an optical clock signal of wavelength. Lambda.. sub.0, wavelength multiplexing means for wavelength multiplexing with optical wavelength signals of the wavelength. Lambda.. sub.0 along with other light wavelength data, and a device in the network In the apparatus of the network, the optical wavelength signal of the wavelength. Lambda.. sub.0 is treated as the reference clock and the other wavelength data is processed.
