100Ghz Polarization Maintaining Dense WDM (DWDM)
The Polarization Maintaining Dense Wavelength Division Multiplexer is manufactured based on environmentally stable thin film filter technology. The DWDM is designed mainly for signals adding/dropping on OADM, and Mux/Demux DWDM communication systems, with the advantage of high isolation, low insertion loss, excellent environmental stability and high power handling capability.
