AON121X 1.2 GHz Optical Node

AON121X Series 1- or 2-port two-way Optical Node is part of ACT Deep Fiber solution, which has been designed to deliver interactive CATV, high capacity DOCSIS Data and other advanced services. The cost-effective node platform helps service providers expand bandwidth of their existing HFC network while minimizing capital investment.

    High response PIN photoelectric conversion tube.

    Optimized circuit design, SMT process production, optimized signal path, make the photoelectric signal transmission smoother.

    Specialized RF attenuation chip, with good RF attenuation and equilibrium linear, high accuracy.

    GaAs amplifier device, power doubler output, with high gain and low distortion.

    Single Chip Microcomputer (SCM) control equipment working, LCD display the parameters, convenience and intuitive operation, and stable performance.

    Excellent AGC performance, when the input optical power range is -9 dBm to +2 dBm, the output level remains unchanged, CTB and CSO basically unchanged.

    Reserved data communication interface, can connect with the Ethernet transponder, access to network management system.

    Return emission can select burst mode to sharply decrease the noise convergence and reduce the forepart receiver number.

    ONU module optional.
