PM Fiber WDM
Polarization Maintaining Filter Wavelength Division Multiplexers
(PMFWDM Series )
The PM FWDM series provide wavelength division multiplexing while maintaining signal
polarization. The components are 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.
