TeliaSonera International Carrier raising capacity with Infinera’s super-channel SD-FEC solution

11 Sep 2013

Infinera, a US-based provider of Intelligent Transport Network solutions, has announced the completion of a test to double the capacity on a key link in TeliaSonera International Carrier’s (TSIC) North American terrestrial network using what it calls ‘the world’s first super-channel implementation of Soft Decision Forward Error Correction (SD-FEC)’. Infinera also announced that the SD-FEC capability is now generally available as an integrated feature of its DTN-X platform, which provides long haul super-channels based on 500Gbps Photonic Integrated Circuits (PICs) and the FlexCoherent Processor chip, and has been deployed by carriers in 30 countries.

The test was performed on TSIC’s Houston to Phoenix fibre link and verifies the ability of Infinera’s SD-FEC technology to double the available transmission capacity on this network link. SD-FEC is an advanced error detection and correction technology that enables transport networks to deliver error-free digital information at extremely high data rates and over very long distances, offering networks greater capacity and reach without the need to regenerate the signal en route, Infinera’s press release continues. TSIC has deployed an Infinera Intelligent Transport Network in North America and in northern Europe.

In other TeliaSonera group news, the Swedish company has reached an agreement to sell its indirect stake in Nepal Satellite to Zhodar Investment.
