PL170A-3: High-Gain FTTH WDM Node for GPON Triple-Play Networks<\/h2>\n

A compact and powerful FTTH optical receiver with integrated FWDM for smooth CATV and data integration.<\/p>\n

    \n
  • Triple-Play Optimization:<\/strong> This FTTH wdm node<\/strong> effectively filters the 1550nm CATV signal while passing the 1310\/1490nm GPON signals to the ONU for high-speed internet and voice services.<\/li>\n
  • Advanced MMIC Amplification:<\/strong> Utilizes a high-performance MMIC amplifier IC<\/strong> to ensure superior non-linearity characteristics and high-definition TV picture quality with low noise.<\/li>\n
  • Wide-Range Optical AGC:<\/strong> Features a reliable Automatic Gain Control<\/strong> (-10 to 0dBm) that maintains a stable RF output level of \u226580dB\u00b5V, even under fluctuating fiber link conditions.<\/li>\n
  • Field-Adjustable Balancing:<\/strong> Equipped with a built-in adjustable attenuator (0~-20dB)<\/strong>, allowing technicians to optimize the signal strength for the subscriber’s specific coaxial cabling.<\/li>\n

    Technical FAQ: PL170A-3 FTTH WDM Node<\/h2>\n
    \n

    Q1: How does a WDM node reduce the complexity of FTTH installations?<\/h3>\n

    A:<\/strong> By integrating the FWDM component<\/strong> directly into the receiver, the PL170A-3 wdm node<\/strong> eliminates the need for separate external filters. It acts as a single-entry point for the fiber, providing a dedicated RF output for TV and a COM\/Pass port for the data ONU, saving space and reducing connector loss.<\/p>\n<\/div>\n

    \n

    Q2: What is the benefit of the wide-range AGC in the PL170A-3?<\/h3>\n

    A:<\/strong> The Automatic Gain Control (AGC)<\/strong> compensates for variations in optical input power from -10 to 0dBm. This means that even if the fiber signal weakens slightly due to splitters or distance, the subscriber will still receive a steady 80dB\u00b5V RF signal<\/strong> without screen flickering or signal loss.<\/p>\n<\/div>\n

    \n

    Q3: Is this WDM receiver compatible with 4K and digital TV?<\/h3>\n

    A:<\/strong> Absolutely. With a frequency range up to 1002MHz<\/strong> and high-performance Pin Diode technology, the PL170A-3<\/strong> is fully optimized for digital QAM, HDTV, 4K, and traditional analog signals in any RF overlay environment.<\/p>\n<\/div>\n<\/div>\n
