Transmission 1310nm Reflect 1490/1550nm Filter-based WDM Multiplexers
FWDM, is known as Filter-based WDM or Filter WDM. It is based on Thin Film Filter (TFF) technology. The Filter WDM is extensively used in WDM networks ,EDFA, Raman amplifiers, and fiber optic instrumentation. The device combines or separates light at different wavelengths in a wide wavelength range. They offer very low insertion loss, low polarization dependence loss, high isolation and excellent environmental stability.
GEZHI's FWDM product family covers following wavelength windows commonly used in optical fiber systems
