Paper Tu2B.2 – Do-il Chang will talk about a 150 x 100G field trial over 1,504 km using all-distributed Raman amplification with 61nm optical spectrum and with excellent transmission performance in field conditions.

On Thursday 13 March, Herve Fevrier will participate in the 100G Deployment on Submarine Links panel (Panel Th1B). The workshop will cover the views of global system operators, transmission equipment manufactures and turnkey system suppliers about the unique set of challenges in deploying spectrally efficient high bit rate transmission technologies on the longest reach among all optical transmission links presented by subsea cable systems.

Xtera pioneered Raman optical amplification in backbone networks with the installation of Raman amplifiers with a 100nm optical spectrum in commercial terrestrial networks in 2004. Xtera was the first supplier to introduce Soft-Decision Forward Error Correction (SD-FEC) in a 100G commercial network in 2011. In April 2013, Xtera launched the industry’s first optical repeater featuring Raman amplification for long-haul subsea cable systems. More recently, in December 2013, Xtera introduced the XWDM solution that makes possible a [Capacity x Reach] metric which exceeds, by a factor of six, what is normally achievable by today’s 100G optical transport systems that use Erbium-Doped Fiber Amplifiers (EDFAs).
