Global Foxcom optical links offer a full range of L-Band, IF & C, X & Ku Band frequencies and are deployed by major satellite operators and broadcasters around the world.
Satellite Antenna Site Diversity
The Challenge:
To provide multi-channel RF-linkage to remotely located earth stations for site diversity to mitigate the impact of adverse weather conditions.
The Solution:
Global Foxcom’s RF Over Fiber (RFOF) Platinum series was deployed to transfer satellite signals to mirrored teleports at distances in excess of 100km.
Turnkey Benefits of Global Foxcom’s RFOF Solutions
Using FIBER rather than coax cables has multiple advantages
Distance
Transmits signals over distances of 100km without signal degradation
Flexible
Lightweight & flexible
Unlimited Bandwidth
Operates without optical loss at any bandwidth
Immune to EMI/RFI
Does not conduct electricity. It is safe during lightening/electrical storms
Security
No optical leakage
Cost Effective
Most cost effective medium for transporting signals
RF Over Fiber Advantages
- Fiber can transmit signals over distances of 100km without single degradation.
- Fiber is lightweight, flexible, and has less optical loss than coax cables.
- Fiber has unlimited bandwidth.
- Fiber does not conduct electricity, so it cannot be damaged during electrical / lightning storms.
- Fiber tapping does not occur because optical leakages do not exist in the system.
- Fiber is the most cost effective material for transporting signals.

FAQs
What are the key components of an RFoF system?
- Optical Transmitter: Converts RF signals into optical signals using a laser diode.
- Optical Fiber: Medium for transmitting the optical signals over long distances.
- Optical Receiver: Converts the optical signal back to an RF signal using a photodetector.
- RF Amplifiers: Used for signal boosting at both the transmission and reception ends.
Does RFoF require special fiber optic cables?
Standard single-mode fiber (SMF) is commonly used for RFoF applications due to its low attenuation and ability to support long-distance transmission.
How does RFoF compare to Digital RF over Fiber (D-RFoF)?
- RFoF: Analog transmission of RF signals over fiber, maintaining original signal characteristics.
- D-RFoF: Digital conversion of RF signals before transmission, which can reduce noise but adds latency and requires extra processing.
Can RFoF be used in 5G networks?
Yes, RFoF is increasingly used in 5G infrastructure for backhaul, fronthaul, and remote radio head (RRH) connections due to its low latency and high-frequency capabilities.
How does temperature affect RFoF performance?
Temperature variations can impact laser diodes and optical fibers, causing signal drift. Temperature-stabilized components help mitigate these effects.
Is RFoF compatible with existing RF systems?
Yes, RFoF can integrate with traditional RF systems using appropriate interfaces and converters. It is often used to extend or replace parts of existing RF distribution networks.
