Now there's a name we don't see too often nowadays... VTLWaveNet, the wholesale network remnant of Viatel, is providing the dark fiber underlying SURFnet's latest project. The Dutch research network is always putting the latest equipment and network designs through their paces.
Here, they've built a 100G link all the way to CERN down in Geneva. The 23 span, 1,650km route is built on a VTLWaveNet's Netherlands-Belgium-France-Switzerland fiber route, and is said to be the longest 100G link yet deployed. They're using Ciena gear, as they have in other 100G builds this year. CERN tends to produce massive streams of research data, making it ideal for 100G trials in the research and education sphere.
I'm always a bit surprised that VTLWaveNet's fiber holdings are still independently held, as they seem to have been an easy M&A target for quite some time. But actual fiber M&A is fairly uncommon still in Europe, unlike here in the US where it has been flying off the shelves.
