PL8130B: Compact Bi-Directional Outdoor RF Amplifier Line Extender
A high-performance, cost-effective distribution solution designed to extend the reach of HFC networks and ensure consistent signal levels at the subscriber drop.
- Full 1GHz Broadband Performance: Сайт PL8130B outdoor RF amplifier covers the 5MHz to 1002MHz spectrum, providing a robust 30dB forward gain to compensate for passive coaxial losses in multi-dwelling units and neighborhood distribution.
- Integrated Bi-Directional Design: Purpose-built for modern interactive cable services, featuring a high-performance return path (5-42/65MHz) that supports high-speed DOCSIS upstream data without additional external modules.
- Compact Form Factor: Engineered for space-constrained outdoor deployments, its small-footprint aluminum housing offers IP-rated weather protection and simplified mounting on strands or pedestals.
- Signal Conditioning: Equipped with independent forward/return attenuators and equalizers (EQ), allowing technicians to fine-tune the output slope and level for optimal CTB (≥67dB) и CSO (≥66dB) performance.
- Surge Protection: Built to withstand harsh field conditions with 5kV (10/700μS) shock voltage resistance and wide-range power options (Line-powered 35-90VAC or Mains 110-245VAC).
Technical FAQ: Outdoor RF Amplifier
Q1: When should I choose a Line Extender like the PL8130B over a Trunk Amplifier?
A: Сайт PL8130B outdoor RF amplifier is ideal for the last stage of signal distribution. While Trunk Amplifiers are for long-haul signal transport, the Line Extender provides a “final boost” to signals before they enter the subscriber’s home, offering a much higher ROI for short-distance coverage.
Q2: How does the PL8130B simplify onsite testing for technicians?
A: Efficiency is key in the field. This outdoor RF amplifier includes four dedicated test points (Forward Input/Output, Return Input/Output), allowing engineers to measure and balance the entire bi-directional link without disrupting the live service to existing customers.
Q3: Is the frequency split adjustable for different global markets?
A: Yes. The PL8130B supports flexible frequency configurations (e.g., 5-42/54-1002MHz or 5-65/85-1002MHz). This adaptability ensures compliance with various international band-plans for CATV and HFC networks across Europe, Southeast Asia, and Russia.
