PL800B: High-Gain FTTB Optical Receiver for MDU Distribution
A professional-grade FTTB node designed for high-density residential buildings and fiber-to-the-building deployments.
- High Output Capability: Delivers a powerful 102dBµV ~ 106dBµV output, capable of driving a 4-way or 8-way splitter to cover multiple households.
- Superior Linearity: Built with Power Doubler amplifier modules to ensure excellent CTB/CSO performance even at high output levels.
- Optical AGC Precision: 集成功能 自动增益控制 (-8 to +2dBm) to maintain a rock-steady RF output despite fluctuating fiber link losses.
- Plug-in Configuration: 采用标准 JXP-style plug-in attenuators and equalizers for quick, accurate field balancing and maintenance.
- Rugged MDU Housing: Encased in a durable, heat-dissipating aluminum alloy housing suitable for wall-mount installation in building corridors or basements.
Technical FAQ: PL800B FTTB Optical Receiver
Q1: What is the main difference between an FTTH and an FTTB optical receiver?
A： An FTTB optical receiver like the PL800B is designed for “Fiber-to-the-Building.” Unlike micro FTTH receivers that serve one home, the PL800B provides a much higher RF output level (100dBµV+), allowing you to distribute CATV signals to an entire floor or multiple apartments through a coaxial distribution network.
Q2: How many TV outlets can a single PL800B support?
A： With its dual RF output ports and 106dBµV maximum level, a single PL800B can typically support 16 to 32 TV outlets depending on the passive splitter loss and cable distances. This makes it an extremely 物有所值 solution for MDU projects.
Q3: Does it support remote network management?
A： The standard PL800B is a localized high-performance node. However, we offer an SNMP-enabled version that allows operators to monitor optical input power and temperature remotely through our centralized management platform.
