Product overview

DWDM: Dense Wavelength Division Multiplexing is a metropolitan area network backbone layer or a long wavelength division transmission technology. It transmits signal by making different ITU-T DWDM wavelength signals multiplex to single fiber in receiving terminal. It decomposes composite signal into different ITU-T DWDM wavelength signal.
