Swedish Internet Exchange deploys WDM from Transmode


Stockholm, Sweden - The Swedish Internet Exchange (Netnod) has significantly reduced customer costs by deploying an optical networking solution from Transmode, a leading provider of Optical Networking Solutions.

ISPs in Sweden are able to interconnect securely via Netnod as it provides the National Internet Exchange-points across the country. The five exchange points are housed in underground bunkers in Stockholm, Gothenburg, Sundsvall, Luleå and Malmö. These bunkers were originally built by the Swedish Government to house critical telecommunications infrastructure. Netnod has deployed the Transmode TM-Series in order to increase the capacity and reliability but mainly to reduce its costs.

“Not only have we significantly reduced the number of fibers we connect to, as well as our costs, but we have also been able to significantly increase the capacity of the network. The Transmode installation has directly led to an increase in the number of our ISP customers,” said Netnod’s CEO Kurt-Erik Lindqvist.

“Having decided we needed a WDM solution, we sent an RFP to seven telecommunications vendors, and after an exhaustive selection process we chose the Transmode TM-Series,” added Lindqvist. “Only two companies could meet our specification due to our particular network requirements. We selected Transmode on price and the ability to meet our delivery times.”

“This Netnod installation is yet another example of how Transmode’s WDM solutions are enabling national Internet exchanges to improve their performance – both in terms of capacity and value for money,” commented Björn Andersson, Transmode’s VP Sales. “We have already implemented similar successful installations in London’s LINX and Dublin’s INEX Internet exchanges.”
