Researchers will this week demonstrate a newly-refined data-transmission technique that can deliver one terabit per second (Tbps) over optical fiber. Nokia Bell Labs, Deutsche Telekom T-Labs, and the Technical University of Munich will be showing off how a technique called Probabilistic Constellation Shaping, or PCS, can deliver blistering 1Tbps speeds over a fiber connection. The work provides more momentum behind the push to bring terabit networks to reality. It follows another optical breakthrough earlier this year by researchers at University College London, who achieved speeds of 1.25Tbps. To put that in perspective, they noted it was fast enough to download an entire Games of Thrones series in high definition within one second.
