ABSTRACT:
An optical wavelength multiplexing add/drop apparatus branches a received optical wavelength multiplex signal into a plurality of parts. Desired information to be received is selected from a plurality of signals multiplexed in a branch signal. Information to be transmitted is converted into an optical signal of an unused wavelength and the optical signal is transmitted after wavelength-multiplexing thereof with a plurality of signals multipelxed in another branch signal. Thereby, simultaneous transmission to a plurality of optical communication devices becomes possible. Also, an optical wavelength multiplexing cross-connection device is constructed with use of optical couplers having a small circuit scale, thereby realizing a small-sized cross-connection device.
