R1490nm FWDM
PON Multiplexer T1550nm R1310/1490nm FWDM Device with SC connector pigtailed
GEZHI PON Multiplexer is based on thin film filter technology with T1550nm R1310&1490nm. The device features epoxy free optical path, low insertion loss, high extinction ratio, high reliability and high stability.
The PON Muitplexer T1550nm R1310/1490nm is 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".
