FTTX Filter WDM module offers very low insertion loss, low PDL, high isolation and excellent environmental stability. Optico 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, 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".
