Polarization Maintaining Dense Wavelength Division Multiplexer for GPON Networks
Product Overview
Gezhi Photonics Polarization Maintaining Dense Wavelength Division
Multiplexer series is designed and manufactured to international
standard, the PM DWDM can preserve the polarization of optical
signals. The devices use environmentally stable Thin Film Filters
and advanced packaging technology to achieve a wide passband, low
insertion loss, high channel isolation, excellent environmental
stability and high extinction ratio. The Polarization Maintaining
Dense WDM can be used individually to perform a single channel add
or drop function or it can be used in DWDM systems and sensor
systems.
