Filter Wavelength Division Multiplexer FTTH/FTTx 1310/1550/1490nm EPON FWDM Filter WDM
Description:
Filter-based Wavelength Division Multiplexer (FWDM) is a kind of WDM multiplexer based on the Thin Film Filter (TFF) technology.
The FWDM combines or separates light at different wavelengths in a wide wavelength range and is extensively used in EDFA, Raman amplifiers, and WDM optical networks.
We provides a series of FWDM multiplexers for FTTx constructions.
All the FWDM multiplexers offer low insertion loss, low polarization dependence, high isolation and excellent environmental stability.
FTTX Filter WDM module is based on Thin Film Filter (TFF) technology.
The device combines or separates light at different wavelengths in a wide wavelength range.
They offer very low insertion loss, low polarization dependence, high isolation and excellent environmental stability.
Our FTTH/FTTx 1310/1550nm FWDM Filter WDM can realize the multiplexing and de-multiplexing of communication optical signals of 1310nm and 1550nm. 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.
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".
Features
● Wide bandwidth
● Low insertion loss
● High channel isolation
● Exceptional reliability and stability
