Wavelength division multiplexer and regenerative repeating method in wavelength division multiplexing network
Abstract:
Disclosed is transponder (optical transmitter/receiver) that has a switch, which switches on and off the loopback of an optical path, to allow the same transponder to implement the transmission/reception end function on an optical path, and the regenerative repeating function at an intermediate point on an optical path. When a new optical path is built, the assignment of the wavelength and the allocation of the incoming and outgoing paths for transmission/reception are set remotely.
