Product Overview
PL170A-3 FTTH Mini WDM node is designed for GPON triple play networks. It has two Optical Connectors. One is to receive combined signals from GPON EDFA , the other connector seperate GPON signal ONU. PL170A-3 FTTH Mini WDM node filt the combined signal and only get 1550nm for CATV broadcasting service, and pass through GPON signal 1310/1490nm for data, internet and voice service. PL170A-3 FTTH Mini WDM node has wide range of AGC from -10 ~0dBM, and also it adopts excellent o-e converter tube with low-noise MMIC Amplifier IC, which is suitable for FTTH networks upgrade.

PL170A-3: High-Gain FTTH WDM Node for GPON Triple-Play Networks
A compact and powerful FTTH optical receiver with integrated FWDM for smooth CATV and data integration.
- Triple-Play Optimization: This FTTH wdm node effectively filters the 1550nm CATV signal while passing the 1310/1490nm GPON signals to the ONU for high-speed internet and voice services.
- Advanced MMIC Amplification: Utilizes a high-performance MMIC amplifier IC to ensure superior non-linearity characteristics and high-definition TV picture quality with low noise.
- Wide-Range Optical AGC: Features a reliable Automatic Gain Control (-10 to 0dBm) that maintains a stable RF output level of ≥80dBµV, even under fluctuating fiber link conditions.
- Field-Adjustable Balancing: Equipped with a built-in adjustable attenuator (0~-20dB), allowing technicians to optimize the signal strength for the subscriber’s specific coaxial cabling.
- Dual-Status LED Display: Integrated Power/Optical indicators provide immediate visual feedback on device power and optical input health, simplifying home-user support.
Technical FAQ: PL170A-3 FTTH WDM Node
Q1: How does a WDM node reduce the complexity of FTTH installations?
A: By integrating the FWDM component directly into the receiver, the PL170A-3 wdm node 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.
Q2: What is the benefit of the wide-range AGC in the PL170A-3?
A: The Automatic Gain Control (AGC) 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 80dBµV RF signal without screen flickering or signal loss.
Q3: Is this WDM receiver compatible with 4K and digital TV?
A: Absolutely. With a frequency range up to 1002MHz and high-performance Pin Diode technology, the PL170A-3 is fully optimized for digital QAM, HDTV, 4K, and traditional analog signals in any RF overlay environment.
