1x2 Ports FWDM module Transmission 1550nm Reflction 1310&1490nm
GEZHI's 1x2 Ports FTTX Filter WDM module extensively used in Raman amplifiers, EDFA, fiber optics instrumentation and WDM networks. It is based on Thin Film Filter (TFF) technology. The device combines or separates signal (1310/1490/1550nm) at different wavelengths in a wide wavelength range. The 1x2 Ports FWDM Module can expand the capacity of a single fiber to achieve bidirectional communication, so that widely used in optical network expansion and upgrade, or introduce new comprehensive business etc.
GEZHI provides 1x2 Ports FWDM Module 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 GEZHI's 1x2 Ports FWDM Module is a place where all this get's "mixed".
