Denmark Boasts Biggest Fiber Network

COPENHAGEN -- Europe’s largest fibre-optic connection now runs through the ground under Denmark’s capital city, Copenhagen. The cable comprises 624 fibre-optic wires, with a total capacity to transfer volumes of 50 million gigabits – equivalent to 500 million phone lines – a second. The cable was laid on the 1st and 2nd of February 2003 and is a good 10 km long. Danish company, Cablux, undertook the technical work for the installation.Europe’s largest fibre-optic cable comprises a so-called redundant connection (every 5 km, two lines are drawn between the same two points for optimum data security). The 10-km long cable was bought by a Danish company in the Copenhagen area, which before now used a connection with 480 fibre-optic wires, but this capacity was no longer enough. Therefore, the fibre-optic connection was expanded using a cable containing an additional 624 fibre-optic wires – a number not exceeded by any other cable laid in Europe to date.“Optical connections of this size are used to transfer data between two places, for example, when it is extremely important that there is a precise copy of the data available at the same moment it is updated. For example, this would be the case with large server parks, where there must always be a 100% identical backup, so that customers never risk losing information under any circumstance,” explains Henrik Mütze, Sales and Marketing Director of Cablux A/S, the company which undertook the contract.In addition to projects in Denmark, Cablux has been involved in projects in Germany, Sweden, Iceland and the Faeroes – including work with the offshore industry’s drilling platforms and large wind farms.Cablux A/S
