Description:
Filter-based Wavelength Division Multiplexer (FWDM) is a kind of WDM multiplexer based on the Thin Film Filter (TFF) technology.

The FWDM combines or separates light at different wavelengths in a wide wavelength range and is extensively used in EDFA, Raman
amplifiers, and WDM optical networks. 



Features:
Low Insertion loss
High Channel Isolation
Low Polarization Dependent Loss
Application:
Fiber Amplifier
CATV Fiber Optic Links
Long-hual,Metro,Access and FTTx
