C&W Networks, part of Cable & Wireless Communications (CWC), has selected Xtera Communications for upgrading its submarine cable systems in the western Atlantic ocean and the Caribbean Sea to 100G.

C&W Networks has bolstered its subsea network capacity by upgrading several unrepeatered and repeatered segments to 100G, using Xtera’s Nu-Wave Optima multi-purpose optical networking platform. The submarine cable systems were upgraded with new 100G channels to include the 1,570 km Gemini – Bermuda cable system, the 1,700 km Caribbean – US (CBUS) cable system, the 1,700 km East West Cable (EWC) system, the 1,440 km festoon Eastern Caribbean Fiber System (ECFS), and part of the 8,700 km ARCOS-1 submarine ring.

“The global build-out of data centers, coupled with rapid deployment of cloud-based services, are driving renewed demand for even higher fixed and burst rate connections with emphasis on high availability through redundancy,” said Paul Scott, President of C&W Networks. “Our goal is to proactively prepare our networks with the right technology to efficiently address the evolving business needs of today and the future. We are very excited to enhance our network performance to 100G and 100G+ and Xtera was a natural choice for us.”

“Strengthening our relationship with C&W Networks, these new upgrade projects are further evidence of the confidence network operators place in Xtera’s capabilities to improve subsea optical transmission infrastructure already deployed across the world,” said Jon Hopper, President and Chief Executive Officer of Xtera. “Upgrading existing subsea cable systems to increase their capacity and extend their lifetime – from a capacity-cost perspective – is part of our subsea solution portfolio, which includes subsea cable recovery and re-lay, as well as new build.”
