Product Details

1x2 Filter 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".
