1x2ch FWDM Filter-based Wavelength Division Multiplexer compact plastic ABS box with FC/APC connector
 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. Powerlink provides a series of FWDM multiplexers for FTTx constructions. Our FWDM product line covers different wavelength windows commonly used in optical fiber systems. All the FWDM multiplexers offer low insertion loss, low polarization dependence, high isolation and excellent environmental stability.
 Features:
 Wide Wavelength Range
 Low Insertion Loss
 High Channel Isolation
 High stability and reliability
 Applications:
 System Monitoring
 Transmitters and Fiber
 Fiber optical amplifier
 CATV System
 FTTH System
