PON Multiplexer T1550nm R1310/1490nm FWDM
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.

  • PON Multiplexer T1550nm R1310/1490nm FWDM Device 

     

     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".

     

    Features

    Pass(Transmission)Channel: 1550nm
    Reflection Channel: 1310nm and 1490nm
    High Isolation, Reliability and channel isolation
    Low Insertion loss and excellent environmental reliability

     

    Applications

    CATV
    WDM system
