Product update – GNSS/GPS-over-Fibre (12 June 2024)
This is the first in a short series of product updates, starting with GNSS/GPS-over-Fibre systems.
Fibre optic links are a popular choice for extending the reach of antenna cables far beyond the limitations of traditional coaxial cables.
The inherent immunity of optical fibre to electromagnetic interference (EMI) allows for installation in challenging environments, such as proximity to high voltage cables.
Our range includes solutions for both single-mode and multi-mode optical fibre.
Single-mode fibre systems can typically be shipped within 2-3 days, while multi-mode fibre systems are custom-built with a lead time of four weeks.
GPS over single-mode fibre
ViaLiteHD RF-to-optical (TX) and optical-to-RF (RX) modules are straightforward to install and include efficient fault monitoring circuitry.
They can extend the antenna to receiver distance up to 10km when necessary, although typically the link spans only a few hundred meters.
These modules are available either as standalone units or as components of a comprehensive system that includes an outdoor antenna, coaxial cables, and pre-terminated fibre

As well as single optical links, there are RF and optical splitter solutions to allow up to 64 devices to share a single outdoor antenna
GPS over multi-mode fibre
Multimode fibre (MMF) is primarily utilised for short-range communication, often within buildings or on campuses.
MMF is frequently found in abundance in such settings, facilitating data traffic between switches and routers within the network infrastructure.
The RVL-1 system from Forsberg leverages existing MMF systems, and can transport GNSS signal over a maximum fibre length of 1500 meters

RVL-1 is a very cost-effective solution that utilises what may be an existing resource.
Out of interest …..
I often use the terms “GNSS-over-fibre” and “GPS-over-fibre” interchangeably.
Do you do the same? Ever wondered what the difference is, if any?
I hope you find the explanation here useful.
