National and International use of light paths
Customise your network connections
In the Netherlands SURFnet provides a NetherLight connection to providers who deliver their services via Ethernet. Via NetherLight, a light path can be set up between the service provider and the client institution.
SURFnet also offers the option of setting up international light paths. Although we are working on standardising the installation of international light paths this is often a custom solution. SURFnet will assess whether a location outside SURFnet is accessible via a light path on a case-by-case basis.
100 Gbit/s Transatlantic
International light paths are primarily used for transmitting research data. For instance, a Transatlantic connection between North America and Europe was established with a speed of 100 Gbit/s, which subsequently became a redundant 100Gbit/s ring network.
For destinations within European NRENs (National Research and Education Networks) light paths are available via the hybrid GÉANT network and/or via SURFnet's cross-border connections in Hamburg, Brussels, Geneva, Paris, London, Hasselt and Aachen.
NetherLight open optical exchange
Light paths can also be connected internationally via open optical exchanges. Within a short period of time NetherLight (established by SURFnet in Amsterdam) has evolved into one of the largest open optical exchanges in the world. View the parties that are connected to NetherLight.
