SURF network

The network is the foundation of all ict facilities at your institution. No education, research and innovation with ICT without a stable network. That is why we at SURF continuously work on a reliable, flexible and powerful network.

Podcast What you need to know about... network resilience

You only realise how dependent you are on a network… when it goes down. In this episode of SURFshort, Harold Teunissen, Head of Network at SURF, and presenter Eva van Dam discuss network resilience. No institution is alone in this. Our network expert’s call to action: “We need to get used to the fact that things don’t always just work.”

Unprecedented precision with new Time&Frequency technology

Vibrations and time transfer

SURF Time&Frequency gives researchers access to unprecedented measurement precision via fibre. University lecturer Jeroen Koelemeij, for instance, uses the service to measure atomic vibrations to twelve decimal places. The technology is also being investigated as a safer alternative to GPS. Read how it works in this real-life story.

What you need to know about... fiber sensing

All across the Netherlands, fiber-optic cables are in the ground. But did you know that besides carrying data, they can be used for entirely different purposes as well? Fiber optics can provide scientists with a wealth of information by measuring strain, pressure, vibrations, or temperature. SURF is exploring the possibilities of this technology, known as fiber sensing, and its potential for research is significant.

Fiber sensing: today's technology

Fiber sensing is a technology in which fiber-optic cables are used as sensors. This technology allows us to monitor not only the fiber itself, but also its immediate surroundings. For example, strain, pressure, vibration, temperature and other physical parameters are measured. Both within the cable and in the environment in which it is located.

We have SURF. Because all colleges and universities are in the same network system, the basic infrastructure is already there. That is the prerequisite for cooperation.
