Product Overview of PM Filter WDM
Customizable Fiber High Power Polarization Maintaining Filter WDM
(up to 20W) for CWDM/DWDM Module
Polarization Maintaining Filter WDM
GEZHI polarization maintaining filter WDM series provide wavelength
division multiplexing while maintaining signal polarization. PM
FWDM is based on environmentally stable thin film filters
technology and are characterized with high extinction ratio, low
insertion loss, and high return loss. They are ideal for high speed
WDM network systems.
