FTTH / FTTx Filter WDM Device , Coarse Wavelength Division Multiplexer
FTTX Filter WDM module extensively used in EDFA, Raman amplifiers,
WDM networks and fiber optics instrumentation is based on Thin Film
Filter (TFF) technology. The device combines or separates light at
different wavelengths 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 business etc.
GEZHI Photonics provides filter-based wavelength division
multiplexing (WDM) filter devices that are customized to the
particular wavelength bands for your special applications. As you
might know, GEPON system itself works on 1310/1490, so CATV signal
here is delivered over same fiber using 1550nm, and FWDM is a place
where all this get's "mixed".
