Implementation optical layer SURFnet8In 2016 the tendering process for the optical layer was completed. ECI Telecom will provide the new optical layer for the SURFnet network. In 2017 and 2018, we will implement this new optical layer.
Upgrade of optical layer
The optical layer illuminates the optical fibres. This layer forms the basis of the SURFnet network and delivers transport functionality to the service layer. With the new optical layer from ECI Telecom, 100 Gbit/s transport capacity will be the standard and 400 Gbit/s will be possible.
About the implementation process
We will migrate the optical layer by branch - a chain of locations between 2 major hubs in the network. Taking a branch-based approach means that the implementation process will take a little longer but, that way, we avoid temporary interruptions to institutions' connections. When work is being carried out in a branch, there will be loss of resilience in part of the network. The institutions will be informed about this well in advance. By working mainly during the day and migrating on a location-by-location basis, we keep loss of resilience to a minimum. We're in control during the work. In the event of increased impact as a result of problems elsewhere in the network, the connections can be recovered quickly and easily.
The engineers have been in training as preparation for the implementation process. On Friday, June 9th, we have deployed a 400 Gbit/s connection between Breda and Utrecht. With this link we have tested ECI’s Apollo platform on a new optical fibre that was not yet in use. At the end of June we started installing the new equipment. At the moment, all of the equipment is installed.
In August, we migrated the first branch in the production network; Zwolle to Nijmegen via Deventer, Apeldoorn and Arnhem. At the moment, 10 branches in the production network have been migrated. The next branch to be migrated is Amsterdam to Utrecht and Utrecht to Almere. We expect to complete the full SURFnet8 migration in October 2018.
ResultsSURF is working on Project SURFnet8, the goal of which is to further develop the fixed section of the national education and research network. Both layers of the SURFnet network – the optical layer and the service layer – will be upgraded.Read more
Implementation SURFnet8Both layers of the SURFnet network - the optical layer and the service layer - are renewed when SURFnet8 is implemented. In 2018, we will complete the implementation of the optical layer and start implementing the service layer.Read more
