Новая разработка позволила через оптоволоконный кабель длинной в 1 км. переслать информацию со скоростью 1.6 терабайт в секунду!!! Twisted light may boost internet bandwidth A new fibre optic technology could increase internet bandwidth capacity by sending data along light beams that twist like a tornado rather than move in a straight line, say scientists. The discovery comes as internet data traffic is reaching its limit amid mounting demand for bandwidth by users of smartphones and internet-enabled devices, creating problems for network providers. The new technology uses optical vortices, which are like doughnut-shaped laser light beams. Also known as orbital angular momentum (OAM) beams, they were thought to be unstable in fibre until now. abc.net.au/science/articles/2013/06/28/3791903.htm#.Uc0QjfnwlZ8
