Nokia may have departed from the mobile market several of us are not aware of the true probable of the Finnish company. Nokia’s acquisition of Alcatel-Lucent this past year also welcomed Bells Labs (now Nokia Bells Labs) to become a part of the Nokia family. Bell Labs was founded in 1925 by Alexander Graham Bell who invented the first working telephone.
Nokia Bell Labs, along with the Techincal University of Munich and Deutsche Telkom T-Labs, has been practicing on a network velocity enhancement method. Known as Probabilistic Constellation Shaping (PCS), the technique, which received the Bell Labs Reward, can permit data tranny over a fiber interconnection at 1 terabit every second.
As of now, Google’s 1Gbps fiber network provides the best speeds to the house users but the new technology, if launched, will definitely enhance the club.
The research is part of the SASER (Safe and Secure European Routing) task. During the experiments done within the Deutsche Telekom’s fiber network, a terabit/sec velocity was observed which was almost near the Shannon Limit – coined by Claude Shannon 66 years ago – of the channel.
How did they find the terabit rate?
“The trial of the novel modulation approach, known as Probabilistic Constellation Framing (PCS), uses quadrature extravagance modulation (QAM) formats to achieve higher transmission capacity over a given route to significantly increase the unreal efficiency of optical marketing communications, ” reads a TUM blog post.
“PCS changes the probability with which constellation points – the alphabet of the transmitting – are being used. Traditionally, all constellation factors are being used with the same frequency. PCS cleverly uses constellation points with high amplitude less frequently than patients with lesser extravagance to transmit signals that, typically, are more resistant to noise and other impairments. This allows transmitting rate to be customized to ideally fit the transmission channel, delivering up to 30 percent better reach. ”
Claims have happened about practically obtaining the terabit speeds. ZDNet been told by a Nokia Networks spokesperson that a round trip acceleration of 1Tbps has recently been recorded between Stuttgart and Darmstadt cities in Germany.
The technology is yet to be released to the market. A productive application lies in improving the core network facilities for FTTH connections to support the rising data needs due to increasing adoption of streaming and cloud services. The someone said that the technology can be implemented in wireless networks at the present point in time.
Upon September 19, the collaborative research will be offered at the ECOC 2016 in D? sseldorf, Germany.
