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