DWDM Dense Wavelength Division Multiplexer
■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.
■Product features
♦ Low insertion loss
♦ Low polarization dependent loss
♦ High channel isolation
♦ Good environment reliability
♦ High level of integration by plug-in design
