example, there's a fibre optic cable linking the new york stock exchange servers in new jersey, and nasdaq servers in qatar abbing new jersey. a higher speed network will link the exchanges, the laser looks like wally, and uses technology originally developed for the department of defense. >> when our network goes live, it will have the time it takes to move price information between two locations, in imperial terms it will take about 780 microsecond round trip time, and bring it to 350 micro seconds. >> to put that in perspective. that's a 0.00036 of a second savings. imperceptible to you and me, potentially worth millions to a high frequency trader. this quest to trim a fraction of a second extends to the time it takes stock information to travel between london and new york. there are 12 fibre optic cables crossing the atlantic, the last engineered over a decade ago. a new route is plauded, following a straighter line. >> we managed to shave off by beating it, straighter than the existing cable, about 500km off that route, off the cable. that makes it about five milliseconds faster than the fastest cable today.
