Dark Fiber network - Denmark

From 2019 onwards, Relined will supply Dark Fiber connections to Denmark via a G.654.D Low Loss (LL) undersea cable (COBRA Fiber Optic Cable), which runs from Eemshaven to Esbjerg. From Esbjerg, the connection is transferred via the land-based infrastructure to destinations such as Copenhagen, Esbjerg (with an undersea cable connection to the UK), and Bulbjerg (with an undersea cable connection to Norway).

The undersea cable benefits from a unique location in comparison to competing connections. For example, a reliable and super-fast connection between Amsterdam and Copenhagen can be achieved via the cable.

Denmark already has an extensive fibre-optic infrastructure in place. A whole host of carriers are connected to the most popular carrier-neutral data centers, as are landing stations for undersea cables and foreign fibre-optic cable systems that connect the country with the rest of Europe.

Colocation data centers

Most colocation data centers in the country have been established in or near the capital Copenhagen and most data flows in Denmark are exchanged here. Peering is primarily undertaken via private peering in the carrier-neutral data centers or via the Internet exchange point DIX (the Danish Internet Exchange).

COBRA Fibre Optic Cable

The COBRA Fibre Optic Cable, which is the undersea cable that runs between Eemshaven (the Netherlands) and Esbjerg (Denmark) is solely leased out in the form of Dark Fiber. Once on the mainland, the connection is easily picked up again by Energinet, our partner in the COBRA Fibre Optic Cable partnership. Naturally, it is also possible to connect with other carriers such as Global Connect, Telia, Colt, TDC, Zayo and GTT.

Fully redundant

The COBRA Fibre Optic Cable is fully redundant in respect of alternative connections with Denmark. The advantage of this is that we can realise your connection between Amsterdam and Copenhagen with just two operators, whereas a land-based route between countries would normally pass through multiple borders and operators. In addition, it is the light’s speed that determines the level of damping i.e. the delay between the transmission and receipt of data. This reduces latency compared to a land-based route between the same points.
