The Polarization Maintaining Dense Wavelength Division Multiplexer (PMDWDM) is manufactured by using thin film filter (TFF) technology. It provides wide passband, low insertion loss, high wavelength isolation and environmentally stable. It can be used as a single channel add or drop Multiplexers in DWDM systems and sensor systems.
