3 ports fiber optic FTB coupler optical fiber FWDM splitter 1*2 coupler for FTTH

FWDM Optical Filter 3 Channel FC SC APC UPC FWDM 1310nm 1490nm 1550nm Optical Filter Filter WDM module extensively used in optical amplifiers, WDM networks. The device combines or separates light at different wavelengths (1310nm/1490nm/1550nm) 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 upgrade and expansion, or introduce new comprehensive business etc.
It works on 1310nm/1490nm, so CATV signal here is delivered over same fiber using 1550nm, and FWDM is a place where all this get together.

APPLICATION

System Monitoring Transmitters and Fiber Fiber optical amplifier CATV System FTTH Syste

FEATURES
