1310nm 1490nm 1550nm 1625nm Triple-play WDM Filter, FTTH Fiber Optic WDM 1x2


1. WDM Filter is an ideal solution for high power optical amplification system and WDM network.
2. It based on Thin Film Filter F(TFF) technology, and be used in EDFA, Raman amplifiers, WDM networks and fiber opticsdevice.

3. 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".
