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.
