| Product List |
Gezhi Photonics Polarization Maintaining Dense Wavelength Division Multiplexer series is designed and manufactured to international standards. The PM DWDM preserves the polarization of optical signals using environmentally stable Thin Film Filters and advanced packaging technology to achieve wide passband, low insertion loss, high channel isolation, excellent environmental stability and high extinction ratio. These devices can be used individually for single channel add/drop functions or in DWDM systems and sensor systems.
