Abstract

An optical communication equipment comprises shared optical sources to be shared by communication nodes, the wavelengths of optical signals are converted into desired wavelengths according to the addressed information of the corresponding optical label signals by using the shared optical sources, and routed to the addressed communication nodes without being converted into electrical signals by using the wavelength routing function of the cyclic-wavelength arrayed-waveguide grating (AWG). The load of each communication node can be reduced by incorporating the multi-wavelength optical sources , which can be shared among individual communication nodes, into the router.
Further, each communication node is provided with an optical gate or the like for returning the optical signal to the communication node from which the optical signal ha been transmitted through the router in order to adjust the transmission time lag between the optical signal and the corresponding optical label signal by the controllers.
In this way, the setting of the transmission time lag by each communication node can be made easier, thereby largely reducing the work load.
