Alcatel-Lucent today announced that scientists in Bell Labs, the company’s research arm, have set a new optical transmission record of more than 100 Petabits per second.kilometer (equivalent to 100 million Gigabits per second.kilometer).
This transmission experiment involved sending the equivalent of 400 DVDs per second over 7,000 kilometers, roughly the distance between Paris and Chicago. This is the highest capacity ever achieved over a transoceanic distance and represents an increase that exceeds that of today’s most advanced commercial undersea cables by a factor of ten. To achieve these record-breaking results the Bell Labs researchers made innovative use of new detection techniques and harnessed a diverse array of technologies in modulation, transmission, and signal processing
High speed optical transmission is a key component of Alcatel-Lucent’s High Leverage Network architecture, key elements of which have already been selected by leading service providers.
