DWDM Dense Wavelength Division Multiplexer

Product overview

DWDMDense 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
