Scientists have accomplished unexpected transferring capacity and spectral efficacy in an optical communications group trial with a novel modulation method. The breakthrough research could encompass the potential of optical networks to encounter surging data traffic demands.

Nokia Bell Labs, Deutsche Telekom T-Labs and the Technical University of Munich have accomplished unexpected transmission spectral efficacy in an optical communications park trial with a novel modulation method. The breakthrough research could enhance the proficiency of optical networks to meet surging data traffic requirements.

In an optical communications field method, Nokia Bell Labs, Deutsche Telekom T-Labs and the TU Munich exhibited that the performance and flexibility of optical networks can be enhanced when adjustable transmission rates are vigorously adapted to channel conditions and traffic requirements. As a component of the Secure and Safe, European Routing project, the study over a deployed optical a fibre network of Deutsche Telekom accomplished a net transfer rate of one Terabit.

It is near to the theoretical maximum information transfer rate of that route and thus allowing the Shannon Limit of the fibre link. The Shannon Limit was introduced by 1948 by Claude Shannon, Bell Labs. Also, the research is a core milestone in providing PCS could be utilized in the future to enhance optical communication techniques. The results of such joint experiment will be introduced at the European Conference on Optical Communication (ECOC) 2015 in Germany.

“Enhanced capacities, flexibility and reach over deployed fibre infrastructures,” says Bruno Jacobfeuerborn, Director Technology Telekom Deutschland and CTO Deutsche Telekom. “Deustche Telekom offers a unique network structure to analyse and illustrate such exceedingly innovative transmission technologies, for instance. Furthermore, it also offers supports bigger layer test technologies and scenarios.”

“Information theory is the estimation of digital technology and during the Claude E. Shannon centenary year 2016 it is exciting to witness his ideas continues to transfer society and industries,” says Professor Gerhard Kramer, Head of the Institute for Communications Engineering at the Technical University of Munich.

“Probabilistic constellation structuring, an ideology that won a Bell Labs Prize instantly applies the principle of Shannon and allow fibre optic systems transfer data, further, and with unparalleled flexibility,” says Professor Kramer. “The overall success of the nearby collaboration with Nokia Bell Labs, who further introduced the technology and Deutsche Telekom T-Labs, who experimented it under virtual conditions, is satisfying confirmation that the TUM Engineering is a benchmark of outstanding quality, and that the TUM teaching offer students the intellectual materials to compete, gain success and lead globally.”

Marcus Weldon, the president of Nokia Bell labs and Nokia CTO, says that “Future optical networks not only require supporting orders of magnitude bigger capacity, but also the potential to dynamically adapt to channel conditions and demand of traffic. Probabilistic Constellation Shaping delivers great benefits to service offers and enterprises by allowing optical networks to work closer to the Shannon Limit to support the huge datacentre interconnectivity and offer the performance and flexibility needed for modern networking in the digital world.”
