1310/1490/1550nm Filter Type Wdm Steel Tube Optical Fwdm
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
