ABS FWDM Module

Share

Hilink Filter WDM FWDM module extensively used in optical amplifiers, WDM networks. 

The device combines or separates light at different wavelengths (1310nm/1490nm/1550nm) in a wide wavelength range. 

It can expand the capacity of a single fiber to achieve bidirectional communication, so that widely used in optical network upgrade and expansion, or introduce new comprehensive optical transfer solutions etc.
 

Product description

FWDM module works on 1310nm/1490nm/1550/1620, so CATV signal here is delivered over same fiber using 1550nm.
