High Isolation CATV EPON Division Multiplexer FWDM 1310 1490 1550 Filter Wavelength
High Isolation CATV EPON Division Multiplexer FWDM 1310 1490 1550 Filter Wavelength
Description
1310 1490 1550 Filter Wavelength Division Multiplexer FWDM for CATV EPON manufactured by ANC International Co., Limited 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. 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".
