100G/400G Demonstration and Papers by Xtera at OFC 2014

This agreement is a key milestone for Palau Telecoms’ strategy. Under the terms of the agreement, Xtera will design and install the Palau Telecoms system using their innovative subsea optical plant and submarine line terminal equipment. The system will provide high capacity fiber optic connectivity to Guam, enabling connectivity to the US Mainland, the Asia Pacific region, Australia and New Zealand via interconnects with existing and planned submarine cable systems.

Throughout the exhibition in Corning’s booth (#3853), Xtera will demonstrate an unrepeatered 100G transmission on 500 km of fiber with industrial margin for cable repairs using Xtera Raman amplification technology and Corning® SMF-28® ULL optical fiber. This combination offers network design flexibility in high-capacity backbone networks for intermediate site skipping, minimization of regeneration site, and transmission of higher channel rates and new modulation formats. Xtera Raman solution and Corning® SMF-28® ULL optical fiber offer a future-proof solution for long-haul terrestrial networks.

Both Xtera’s papers will be delivered on Tuesday 11 March in the Field Trial Demonstrations and Modulation Formats session:

• Paper Tu2B.1 – Tiejun J. Xia (Optical Technology Planning, Verizon) will present the paper entitled Transmission of 400G PM-16QAM Channels over Long-Haul Distance with Commercial All-Distributed Raman Amplification System and Aged Standard SMF in Field, and co-authored by Xtera. The result shows that Xtera’s commercial Nu-Wave Optima™ optical networking platform enables the effective transport on genuine long distances of high-capacity channels made of multiple 16QAM carriers in deployed long-haul fiber networks.
• 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).

As a leading industry innovator, Xtera has been bringing technical breakthroughs to the optical networking industry for the last decade.
