Polarization Maintaining Filter WDM(PMFWDM)
The Polarization Maintaining filter WDM provides wavelength division multiplexing while maintaining signal polarization. The PM FWDM is characterized with low insertion loss, high return loss, high extinction ratio and excellent environmental stability and reliability. It is ideal for high speed WDM network systems.
