1x2 Polarization Maintaining Filter Wavelength Division Multiplexer for CATV System
Product Overview
The polarization maintaining filter WDM series provides wavelength division multiplexing while maintaining signal polarization. The PM FWDM is based on environmentally stable thin film filters technology and is characterized with high extinction ratio, low insertion loss, and high return loss. They are ideal for high speed WDM network systems.The polarization maintaining filter WDM series provides wavelength division multiplexing while maintaining signal polarization.
