FWDM Device, Filter WDM, Filter Wavelength Division Multiplexers

Product Details

Filter Wavelength Division Multiplexers (FWDM) are based on environmentally stable thin-film filter technology. This FWDM device can realize the multiplexing and demultiplexing between two communication channel. Filter WDM can expand the capacity of single fiber to achieve bidirectional communication, which can widely used in optical network upgrade and expansion, or introduce new comprehensive business etc.

Features
·Low insertion loss
·Low PDL
·High channel isolation
·Excellent environmental reliability

Applications
·WDM system
·CATV
