EXA Infrastructure announced upgrades to its pan-European networks, starting with a key backhaul route in Spain.

EXA is collaborating with fibre optic technology provider, Corning Incorporated, leveraging the company’s ultra-low-loss optical cables.

EXA Infrastructure is utilising the latest high-end specification fibre optic cables across multiple key network routes around the continent in a two-year overpull upgrade. The first project has delivered 300 kilometres of backbone network renewed with hybrid cable, featuring Corning® ALTOS® loose tube outdoor duct cable with SMF-28® ULL optical fibre. Additional projects utilize MiniXtend® cable and SMF-28® ULL optical fiber with 200-micron outer diameter, which supports higher density cables through its lower outside diameter.

In initial testing of the upgraded route from the French border via Barcelona toward Valencia, site-to-site losses on installed cables, including network connectors and splice losses, have been in the range of 0.17-0.18 dB/km for the SMF-28 ULL fibre at 1550 nm, providing EXA Infrastructure with great resiliency and capacity levels required for the most data-intensive customers in the region.

The first upgraded route has seen new cable installed through existing EXA Infrastructure ducts to serve increasing demand in north east Spain. This includes new data centres being developed in Barcelona and new subsea cables being deployed into the city.

“This collaboration will see the very latest fibre technology brought to our network across Europe. By engaging closely with Corning, we will ensure that we are investing in the best quality connectivity and making that available to our customers, starting with our high-demand route in Spain and then targeting priority links across the region,” said Steve Roberts, Senior Vice President Product and Marketing.

“Ultra-low-loss optical fibres, such as our SMF-28 ULL fibres, are instrumental in allowing carriers and cloud operators to achieve long reach and high transmission capacity to meet future bandwidth demand,” said Sharon Bois, Division Vice President, Product Line and Marketing, Corning Optical Fiber and Cable. “Collaborating with EXA on such a large and advanced fibre network provides an excellent endorsement of the quality and scalability of our solutions, and we look forward to the development of this project across Europe.”

Corning’s SMF-28® ULL fibre is the world lowest loss terrestrial fibre. Millions of kilometres have been sold and deployed worldwide, including in the harshest environments and most demanding long-haul applications.
