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
