Product Overview
PL200A-3 FTTH WDM optical receiver has a FWDM filter, which can separate input optical signals into CATV and PON signals. PL200A-3 FTTH WDM optical receiver uses a Pin Diode receiving tube to convert the CATV optical signal to RF signal, which is then amplified and adjusted to keep a high performance and high quality TV picture signal and sent to subscribers’ TV sets. Meanwhile, after being saperated, the PON optical signal is sent to the subscribers’ ONU, where it provides Internet, data, and voice.

Welcome to enquiry PL200A-3 FTTH wdm optical receiver
PL200A-3: Professional FTTH WDM Optical Receiver with High-Linearity
A high-gain, active optical receiver with integrated FWDM, designed for analog and digital TV distribution over GPON networks.
- Advanced O-E Conversion: This wdm optical receiver utilizes a premium Pin Diode tube, ensuring an exceptional CTB/CSO performance of ≥63dB for clear 4K and HD video.
- Precision Optical AGC: Features a built-in Automatic Gain Control (-7 to 0dBm), providing a stabilized RF output level of up to 86dBµV, even if the fiber link loss fluctuates.
- Integrated FWDM Filter: Efficiently separates the 1550nm CATV signal from 1310/1490nm data signals, allowing for a clean GPON pass-through to the subscriber’s ONU.
- Technician-Grade Balancing: Equipped with an on-board adjustable attenuator (0~-10dB), enabling precise RF level matching for complex in-home coaxial distributions.
Technical FAQ: PL200A-3 WDM Optical Receiver
Q1: How does this wdm optical receiver maintain “Excellent Non-linearity”?
A: The PL200A-3 wdm optical receiver is built with high-linearity amplification circuitry. By optimizing the O-E converter’s matching, it minimizes signal intermodulation, delivering a CNR ≥50dB and keeping distortion (CTB/CSO) at industry-leading levels even with a full 98-channel load.
Q2: What is the benefit of the external 9V switching power adapter?
A: Using a high-quality external switching power adapter reduces internal heat within the receiver chassis. This separate design extends the lifespan of the internal optical components and ensures a more stable DC voltage, which is critical for maintaining RF output consistency.
Q3: Can I use this receiver for multi-room coaxial splitters?
A: Absolutely. With a high output level of 86dBµV, the PL200A-3 provides enough “link budget” to drive 4 to 8 TV outlets via passive splitters without requiring an additional drop amplifier, making it a cost-effective choice for large residences.
