Product description
Filter Wavelength Division Multiplexer FTTH/FTTX 1310/1550/1490nm Fwdm Filter WDM
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 upgrades and expansion, or introduce new comprehensive business, etc. FS 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, the GEPON system itself works on 1310/1490, so the CATV signal here is delivered over the same fiber using 1550nm, and FWDM is a place where all this get's "mixed".
