Japanese IT and electronics giant NEC Corporation has been contracted by Facebook to build an ultra-high performance fibre-optic cable under the Atlantic connecting the US and Europe.
The company said it would use its new 24-fibre-pair cable and repeaters, which can deliver a maximum transmission capacity of half a Petabit per second, the highest to date for a long-distance repeatered optical subsea cables.
Until now, subsea cable has been composed of 16 fibre pairs at most, it said.
Data transmission across the Atlantic is expected to expand twenty-fold between now and 2035, NEC said.
The company has built more than 300,000km of cable, enough to circle the earth nearly eight times.
Its subsidiary OCC Corporation manufactures subsea cables capable of withstanding water pressures at depths beyond 8,000m.
