Filter
Wavelength Division Multiplexer
(FWDM Series)
The Filter Wavelength Division Multiplexer series are based on environmentally
stable Thin Film Filters technology. The devices combine or separate
light at different wavelength in a wide wavelength range. They offer
very low insertion loss, low polarization dependence, high isolation
and excellent environmental stability. High power handling capability
can be achieved through unique pigtail processing and high quality
AR coating. These components have beed extensively used in EDFAs,
Raman amplifier, WDM networks and fiber optics instrumentation.
