Extremely high capacity (400 Gbit/s) for education and research in the Netherlands

Direct connection between Breda and Utrecht is first step in implementation of new generation SURFnet network

13 JUN 2017

On Friday, June 9th, SURFnet together with ECI Telecom and Tallgrass deployed a 400 Gbit/s connection between Breda and Utrecht. With 400 Gbit/s, this new direct link offers extremely high capacity for education and research in the Netherlands.

For example, with 400 Gbit/s samples of the human genome project can be sent in a few seconds, and around 2,000,000 concurrent Spotify streams can be supported. The connection between Breda and Utrecht is the first step in the implementation of the new generation of the SURFnet network: SURFnet8.

First 400 Gbit/s connection in the SURFnet network

The connection between Breda and Utrecht is the first direct link between these two locations in the SURFnet network. ECI's Apollo platform is used to provide this first 400 Gbit/s connection for the optical layer on a new optical fibre. This is the kick-off for the implementation of the new optical layer of the SURFnet network.

What the new optical layer offers

With the new optical layer, 400 Gbit/s is possible, and 100 Gbit/s transmission capacity will become standard. The Apollo platform offers high capacity, flexible DWDM transport, with many options for software-based applications and network function virtualisation (NFV) in the future. In addition, optical connections can be recovered automatically. If an optical fibre fails, then an alternative route for transmission is found within seconds so that loss of capacity is reduced to a minimum. Certain parts of the network can also be kept clear of traffic so that SURFnet can carry out maintenance during the day without loss of redundancy and capacity.

Implementation process new generation SURFnet network

The optical layer – responsible for illuminating the optical fibres – forms the basis of the SURFnet network and delivers transport functionality to the service layer. The service layer provides services, like Internet, to institutions. In 2017 SURFnet implements the new optical layer. This will be followed by an advanced service layer in 2018.
