4 x FWDM Module Set
FWDM module combines or separates light at different wavelengths in a wide wavelength range. It can be used to expand the capacity of a single fiber to achieve bidirectional communication.Featured with low insertion loss, low PDL, high channel isolation and excellent environmental stability, the filter is extensively used in EDFA, Raman amplifiers, WDM networks and fiber optics instrumentation.
