8 mW CATV RF Over Fiber Tx 45-870 MHz
RF over Fiber Tx - 8mW Output 45-870 MHz
RF over Fiber Tx – 8mW Output | 45–870 MHz
1310nm CATV RF optical transmitter for transporting analog and digital television RF signals over single-mode fiber.
Product Overview
The F-RF-1310-TX-8mW is a professional RF over Fiber optical transmitter designed to carry the full 45–870 MHz RF spectrum over a single fiber. It directly converts incoming coaxial RF into optical RF, allowing all channels and services within the band to be transported together with excellent stability and low distortion.
This unit is ideal for systems distributing Analog RF NTSC or PAL, Digital QAM / QAM J.83B, ATSC antenna feeds, ATSC 8VSB, ATSC 3.0, and other RF services operating within the supported range. It provides a simple way to move CATV, off-air antenna, and headend-generated RF signals across long distances where coax alone would introduce excessive loss.
Built around a highly linear 1310nm DFB laser with Automatic Gain Control (AGC), the transmitter is optimized for stable multi-channel transport in both point-to-point and passive optical split networks. For expanded deployments, it can be paired with PLC optical splitters and compatible Thor Fiber RF receivers to serve multiple remote locations from one headend source.
Key Benefits
- Transports the full RF band over one fiber
- Supports analog and digital CATV / broadcast RF formats
- Compatible with RFoG-style optical RF distribution
- Suitable for direct fiber links or splitter-based multi-location systems
- Front-panel LCD displays operating status and alarm information
- Optional redundant power supply for higher reliability
Typical Applications
This 8mW RF transmitter is well suited for hotel TV systems, apartment and MDU CATV distribution, campus antenna feed transport, headend-to-building fiber backbones, sports bars, hospitals, stadiums, and enterprise coax TV upgrades.
It is especially useful when a system needs to deliver RF from a central location to remote buildings while preserving signal quality for existing coax-based televisions, set-top boxes, modulators, or RF amplifiers.

Why Use RF Over Fiber?
Fiber allows long-distance RF transport with much lower loss than coax, while keeping legacy CATV and antenna systems active at the remote end.
Real System Diagram Using Thor Products
Example signal flow: HDMI sources enter a Thor modulator, the RF output feeds an RF optical transmitter, the fiber is split using PLC splitters, and multiple optical RF receivers convert the signal back to coax for TVs or local RF amplifiers.
Media Players, PCs
Transmitter can be used with any or Thor Fiber optical RF receivers
• 8 mW Optical Power Output from sensor feedback controlled laser system
• Transports entire 45-1000 MHz band even with full channel linups
• Create high security "Fiber Breaks" to eliminate coax signal return path
• Automatic Gain Control (AGC) manages RF level with no adjustment needed
• Compatible with all Thor RFoG CATV series optical receiver systems
IMPORTANT NOTE*** (it is very important to interface our unit with SC/APC - Angle Polished Connector to avoid any light reflections.
If your fiber is terminated with the SC, ST, FC /PC flat connector, you need to use an optical jumper from PC type to SC/APC for proper conversion.
