(Image source: Ray Fujioka/Flickr)Alcatel-Lucent Submarine Networks (ASN) has announced an innovation, which enables data transmission over a distance of 10,000 km using real-time processing prototypes of 300 gbps

This new modulation technology will help optimise the performance of submarine cable systems whose introduction in Africa has seen the costs of Internet and other telecommunication-related services slashed almost by half. It will also contribute to further deepen the adoption of technology across the continent.

A trial has been made on 10,000 kms of ASN’s test bed, combining the innovative 300G 8QAM (8 quadrature amplitude modulation) technology of ASN’s 1620 SOFTNODE platform and second-generation coherent submarine fibre (CSF-2). 8QAM technology can optimise both existing and new undersea cable systems, enabling operators to deliver more than 15 terabits per second per fibre pair on transoceanic systems, which is equivalent to 2.25mn HDTV channels streamed simultaneously.

Olivier Gautheron, chief technology officer of ASN said, “Our researchers continue to develop new solutions to further apply our own innovation to help traditional and web-scale operators cope with increasing requirements for speed, capacity and cost-effectiveness.”

Fibre optic cables carry much more information and at a faster speed than conventional copper wires and are far less subject to breaks in communications. Consequently, they make Internet and telecommunications more affordable than satellites.
