Ultrafast fiber optics set new speed record

A new broadband speed record has been set - two independent research groups achieved data transmission rate of 100 terabits per second using a single optical fibre. That is equal to the content of 250 double-sided Blu-ray discs.

"This marks a critical milestone in fibre capacity", says Ting Wang at NEC Laboratories in Princeton, New Jersey.

The results considerably exeed today's bandwidth needs.

"Total capacity between New York and Washington DC, one of the world's busiest routes, is only a few terabits per second", says Tim Strong of Telegeography Research in Washington.

According to him "traffic has been growing about 50 per cent a year for the last few years". That means that more and more capacity will be needed in future due to the growing popularity of bandwith-hungry applications, such as social networks and video streaming. The first application of 100-terabit transmission is expected to be inside the giant data centres that power Google, Facebook and Amazon.
