Xtera has announced the completion of the final splice and marine operations on the Guantanamo – Puerto Rico submarine cable system for the Defense Information Systems Agency (DISA).

Xtera, a provider innovative subsea fibre-optic technology, first announced plans for build the private subsea cable system for DISA back in September 2017 and reconfirmed the construction of the system in March of this year when its Xtera founder and CSO Robert Richardson and CTO Tony Frisch spoke exclusively to Capacity.

The international cable ship, the IT Intrepid successfully carried out the marine installation for the project and is due to be fully commissioned in December and placed into service in early 2019 after being fully integrated into the global DISN network.

“The success of this project is a credit to the professionalism of our expert team and their ability to work seamlessly with our industry-leading partners,” said Keith Henderson, chief executive officer of Xtera. “Excellent collaboration between Xtera and the DISA project team has enabled the on-schedule delivery of the system despite regional weather challenges. Once again Xtera has demonstrated that it is the Supplier of choice for those seeking a high-quality innovative optical solution.”

This marks the second submarine cable system that Xtera has deployed for DISA, the first having been deployed and operational since 2015. The cable features Xtera’s second-generation low noise repeater and delivers a high-capacity solution at the lowest cost per terabit per second.

When combined with the Nu-Wave Optima Submarine Line Terminal Equipment (SLTE), which uses patented Raman technology, enabling Xtera to deliver more than 40Tbps on a singer fibre pair.

In May of this year, Xtera was selected by Seaborn Networks for its C+L band design to power its subsea cable system running between Sao Paulo and Buenos Aires as it looks to meet the capacity demands for content providers in the area.
