Technology

The system consists of 2 independent and diversely routed fibre optic segments, each with 20 repeaters on the sub sea part.
Distance covered between Svalbard and Breivika Distance covered between Breivika and Harstad
Segment 1 1375 km (172 km of this buried) Segment 1a 61 km
Segment 2 1339 km (173 km of this buried) Segment 2a 74 km


Currently only one of the 8 optical fibre pairs of each cable is in use, yielding a 10 Gbit/s transmission capacity per cable, with a prospective maximum capacity of 2500 Gbit/s per cable.

The cable has three landing points
