PL160A-3: Indoor FTTH WDM Mini Node with MMIC Amplification
The high-performance WDM optical receiver designed for superior TV picture quality in GPON/EPON triple-play networks.
- MMIC Low-Noise Technology: Built-in MMIC amplifier IC guarantees excellent non-linearity characteristics and crystal-clear HD video distribution.
- Integrated FWDM Filter: This wdm mini node efficiently separates 1550nm CATV signals while passing 1310/1490nm data signals to the ONU for broadband access.
- Precision Optical AGC: Reliable Automatic Gain Control (-10 to 0dBm) ensures a stabilized 76dBµV RF output, even with fluctuations in fiber link loss.
- Integrated ATT Adjustment: Features a built-in mini button for manual attenuation control, allowing on-site output balancing without external pads.
- Eco-Friendly Engineering: Ultra-low power consumption of only 1.2W, making it an ideal “set-and-forget” terminal for large-scale FTTH deployments.
Technical FAQ: PL160A-3 WDM Mini Node
Q1: How does the MMIC amplifier improve the WDM mini node’s performance?
A: Unlike standard receivers, the PL160A-3 wdm mini node uses a high-performance MMIC (Monolithic Microwave Integrated Circuit). This technology significantly reduces distortion (CTB/CSO) and noise, which is essential for maintaining “carrier-grade” video quality at the subscriber’s terminal.
Q2: Can I use this node with existing GPON or EPON equipment?
A: Absolutely. It is fully compatible with any GPON/EPON triple-play architecture. It features a dedicated COM/Pass port with high optical isolation (≥30dB), ensuring data traffic remains unaffected by the CATV overlay.
Q3: What is the benefit of the plastic indoor housing?
A: The PL160A-3 uses a compact, high-quality plastic housing designed for indoor media boxes. Its lightweight and small footprint (94mm x 60mm) make it easy to install in tight spaces while maintaining excellent heat dissipation for long-term reliability.
