The team were able to boost the power of their transmission some 20 fold and push data over a “record-breaking” 12,000km (7,400 miles) long fibre optic cable. Amazingly the data was still intact at the other end and that was achieved without using repeaters and only needing standard amplifiers (the cost of repeaters plays a big part in the overall expense of such networks).
That’s a pretty cool development. In practical terms, it means financial centers on each side of the pond will be able to exchange information with a much shorter round trip delay. It also makes serving your content as close as you can from your users (using a CDN) less useful.
