32 mW CATV RF Over Fiber Tx 45-870 MHz
RF over Fiber Tx - 32mW Output 45-1000 MHz
High Power RF over Fiber Transmitter – 32mW | 45–1000 MHz
Long-distance CATV and broadcast RF distribution over fiber for large-scale networks and FTTH deployments.
Overview
The F-RF-1310-TX-32mW is a high-output RF over Fiber transmitter designed for demanding applications requiring extended reach and large optical distribution networks. Covering the full 45–1000 MHz RF spectrum, it enables transport of complete CATV lineups and RF services over fiber infrastructure.
This unit supports a wide range of modulation types including Analog RF (NTSC / PAL), Digital QAM (J.83B), ATSC antenna feeds, ATSC 8VSB, ATSC 3.0, and other RF signals within band. All services are carried simultaneously over a single optical link, preserving channel quality across long distances.
Built with a high-linearity DFB laser and advanced Automatic Gain Control (AGC), this transmitter is optimized for dense channel loading and high MER performance, making it ideal for modern digital RF environments.
Designed for Large Optical Splits
With a powerful 32mW optical output, this transmitter is engineered for high split-ratio passive optical networks, supporting configurations such as:
- 1x16 and 1x32 fiber distribution
- 1x64 large-scale deployments
- Multi-building or campus-wide RF distribution
This makes it an excellent solution for FTTH RF overlay systems, large hospitality properties, stadiums, military bases, and enterprise-wide CATV distribution over fiber.
Core Advantages
- High optical power for long-distance and multi-node distribution
- Supports full RF spectrum transport over a single fiber
- Optimized for digital QAM and ATSC signal integrity
- RFoG compliant output for wide receiver compatibility
- LCD interface for diagnostics and real-time system monitoring
- Optional dual power supply for critical infrastructure
Application Scenarios
The 32mW transmitter is designed for large and complex RF networks, including:
- Fiber-to-the-Home (FTTH) RF overlay systems
- Hotels, resorts, and large hospitality TV systems
- Sports venues and stadium RF distribution
- Campus and multi-building CATV infrastructure
- Headend to remote node RF transport
- Replacement of long coax trunk lines with fiber
System Integration
This transmitter integrates seamlessly with RF headend equipment such as QAM and ATSC modulators, antenna feeds, and CATV sources. It can be deployed with optical splitters and receivers to create scalable, low-loss RF distribution networks.
