A new data-transmission technique will offer speeds 1,000 times faster than Google Fiber.


Researchers at Nokia Bell Labs, Deutsche Telekom T-Labs, and the Technical University of Munich have developed Probabilistic Constellation Shaping, a data-transmission technique that will have the capacity to provide speeds 1,000 times faster than Google Fiber.

Nokia says the method is able to provide up to 1 Gbps and is fast enough to download a full movie in less than two minutes.

The researchers say the technology should make it possible to download high-definition films and entire seasons of TV shows in a matter of seconds, bringing the field close to the theoretical maximum information transfer rate of that channel, and approaching the "Shannon limit" of the fiber link.

Nokia says the technique uses quadrature amplitude modulation formats to achieve higher transmission capacity over a given channel, to boost optical fiber flexibility and performance in order to move data traffic faster and over greater distances without increasing the optical network complexity.

"Probabilistic Constellation Shaping offers great benefits to service providers and enterprises by enabling optical networks to operate closer to the Shannon Limit to support massive datacenter interconnectivity and provide the flexibility and performance required for modern networking in the digital era," says Nokia Bell Labs president Marcus Weldon.
