The Svalbard Undersea Cable System is a twin submarine communications cable which connects Svalbard to the mainland of Norway. The two optical fiber cable consist of two segments, from Harstad to Breivika in Andøy, and from Breivika to Hotellneset near Longyearbyen in Svalbard. The segments from Harstad to Breivika are 74 and 61 kilometers long, respectively, and the segments from Breivika to Hotellneset 1,375 and 1,339 kilometers. Each consists of eight fiber pairs and there are twenty optical communications repeaters on each segment. Each segment has a speed of 10 gigabits per second (Gb/s), with a future potential capacity of 2,500 Gbit/s. The system is now the sole telecommunications link to the archipelago.
Hibernia Networks, alternately known as Hibernia Atlantic, was a privately held, US-owned provider of telecommunication services. It operated global network routes on self-healing rings in North America, Europe and Asia including submarine communications cable systems in the North Atlantic Ocean which connected Canada, the United States, the Republic of Ireland, the United Kingdom and mainland Europe.

FARICE-1 is a submarine communications cable connecting Iceland, the Faroe Islands and Scotland. The cable has been in use since January 2004 and is 100% owned by the Icelandic state. The cable had an initial design capacity of 720 Gbit/s and is a two fibre pair design. The length of the cable is 1205 km for the direct route between Iceland and Scotland. The cable structure and repeaters were made by Pirelli and the terminal equipment was supplied by TYCO. In the year 2013 the terminal equipment was upgraded by Ciena bringing the total capacity of the submarine cable to 11 Tbit/s. The cable has service access points in Reykjavik and Keflavik Airport as well as in London Telehouse East. The company Farice ehf sells services over the FARICE-1 cable. FARICE-2 was never built. DANICE is the complementary submarine cable.
