Nokia and Deutsche Telekom achieve 1 Tbsp transmission rate over optical fiber

Nokia Bell Labs, Deutsche Telekom T-Labs and the Technical University of Munich achieved a 1 Terabit-per-second transmission rate over optical fiber. The trial was possible due to a new modulation technique dubbed as Probabilistic Constellation Shaping (PCS) which uses quadrature amplitude modulation (QAM) formats to achieve higher transmission capacity over a given channel to improve the … Continue reading "Nokia and Deutsche Telekom achieve 1 Tbsp transmission rate over optical fiber"
