RVL-1 RavenLink GPS Fiber Optic Link System


The RVL-1 Fiber Optic Link System is an affordable GPS fiber optic antenna link system for GPS and GNSS systems, which offers exceptions lightning protection.

SKU: RVL-1-FIBER Categories: , , Manufacturer: Forsberg Services Ltd.

The Forsberg RVL-1 RavenLink GPS Fibre Optic Link System)

The RVL-1 Fiber Optic Link System (formerly Raven StarLink) is an affordable multi-constellation solution for remote GPS antenna installations and was designed to accommodate future expansions of GPS signals. The product covers frequency ranges from from 800 MHz up to 1800 MHz and passes all of the GNSS frequencies (GPS, GLONASS, Galileo, BEIDOU, SBAS, L-BAND) over fiber from a few meters up to 1,524 meters (5,000 feet).
This system offers exceptional lightning protection. Because the fiber optic cable will not pass current induced by lightning strikes, both the th the cable and the system are protected.

This unit has been designed to operate on 12V to 36V AC or DC, allowing the use of low voltage NEC electrical wiring standards to be used at installation. The RVL-1 is designed to operate with any TNC GNSS antenna with at least 34dB gain for a complete solution.

RVL-1 GPS fiber optic link is patented technology. (US8032031 B2)

The RVL utilizes the advantages of fiber optic cable over coaxial including: 

  • Greater distance for remote antenna (up to 1,524 meters)
  • Lower signal loss during transmission
  • Security as the cable does not radiate signals.
  • Immune to environmental factors that affect copper
  • Insulated cable so no electrical current can flow through, therefore providing the ultimate in lightning and surge protection.
  • Immune to electrometric interference and radio-frequency interference.
  • Fiber cable can run beside industrial equipment without concern
  • The cable is lightweight, thin and durable making installation easier to handle, while also taking up less space.
  • Lower costs to maintain than copper cable.
