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.
KEXINT 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".

The Filter WDM system uses a Multiplexer at the transmitter to combine several wavelengths together, each one carry different signal with bite-rate up to 10G and a demultiplexer at the receiver to split them apart.
Due to its low insertion loss, low polarization dependence and high isolation, the filter is widely used in CATV system, FTTx and PON system, Fiber Communication, Test Instrument and etc.
