In 2017, Microsoft and Facebook achieved the best undersea Internet cable project in collaboration with telecom infrastructure company Telxius.
It is the biggest potential undersea telecommunications cable to ever cross the Atlantic, it might actually be extremely faster than we previously thought it could be.
Marea (Spanish for ‘tide’) spreads across 6,400 km of ocean between Virginia Beach and Bilbao in Spain, around 17,000 foot below the surface of the Atlantic. It has the greatest total capacity in the world, theoretically 160 terabits per second (Tbps), equivalent to streaming 71 million HD videos simultaneously. isn’t it shocking and hilarious at the same time?
The cable contains eight optic fibres, and each pair was previously expected to be capable of transfer speeds of 20 Tbps But a new experiment was done using 16QAM modulation accomplished a new record of 26.2 Tbps. That’s huge news.
For one, the experiment was carried out on an existing cable and not a prototype model, meaning it could be upgraded instead of spending millions laying new cables. Secondly, the speed improvement was also carried out over a long distance, meaning it’s real-world viable.
Sadly, though it can score 26.2 Tbps, the average data transfer rate on Marea is yet about 9.5 Tbps, so it’s going to take some time before we can truly see those kinds of speeds on a daily basis.
