We specialize in ruggedized RF Distribution for the professional satcom market.
The Distribution of RF
RF distribution over fiber offers major advantages over traditional coaxial cable in applications where performance, reliability, scalability, and signal quality are important. For modern networks and communication systems, RF transport via fiber optics is becoming the preferred long-term solution.
Both fiber optic and coaxial cable technologies have their place in modern infrastructure. However, for applications that require high bandwidth, low signal loss, long-distance transmission, interference resistance, and future scalability, fiber optic technology offers substantial advantages.
Fiber optic cables transmit data using light, while coaxial cables use electrical signals through copper conductors.
Fiber has several important advantages
• Low signal loss over long distances
• High bandwidth capacity
• Less sensitive to electrical interference and signal disturbances
• Lightweight and easy to install
• Improved signal quality
• Supports growing data and connectivity needs
• Improved signal integrity and data protection
"Our new RF over Fiber platform combines a robust IP67-rated design with user-friendly operation. Its modular architecture allows you to configure, adapt, and scale the solution to meet evolving network requirements.”
Swedish Microwave RF over Fiber system Quad-link simplifies high-performance RF signal transport. The Quad-Link system enables four RF channels to be transported over a single fiber connection while maintaining excellent signal quality over long distances.
The systems are plug-and-play and ready to use without software configuration or complex setup procedures, helping reduce installation time and simplify integration into both new and existing infrastructure. Designed for demanding outdoor environments, the compact IP67-rated devices provide reliable operation even in harsh weather conditions.
Key benefits for customers include:
• Up to 40 km transmission distance
• Four RF channels over a single fiber
• High signal quality with low noise and stable performance
• Reduced cable complexity and infrastructure requirements
• Outdoor-ready IP67 design for demanding environments
• Lightweight and easier installation
• Optional 10 MHz transmission in the reverse direction
• Eliminates gain slope commonly seen in long coaxial cables.
• Compatible with various RF applications and infrastructure systems
• Lower need for amplifiers and signal conditioning equipment
This enables organizations to build scalable and reliable RF infrastructure while simplifying installation. If you need to transport RF signals over distances beyond 20 meters, RF over Fiber should be considered from both a performance and cost perspective.
