Zayo Group Holdings has announced that it is deploying a new diverse subsea cable called Zeus.

Described as a "highly fortified, hybrid, ultra-low-loss (ULL) cable" the system will run parallel but along a diverse to Zayo’s existing Circe North subsea cable, directly connecting the UK to mainland Europe via Lowestoft, UK and Zandvoort, Netherlands.

From a technical standpoint, Zeus has the potential to deliver more than 4,000Tbps of capacity and using Hexatronic’s high-fibre-count cable, it delivers next-gen cable technology including high-capacity 192 fibre, 100% double armoured cable with increased crush resistance and ULL fibre technology for added resiliency.

“The deployment of the subsea Zeus route demonstrates our commitment to expanding our network footprint in Europe while also providing high-quality, essential connections for customers between key global markets,” said Jesper Aagaard (pictured), president of Zayo, Europe.

“This investment will support the steep rise in global demand for bandwidth and capacity in data use and transfer across multiple sectors, primarily driven by a shift towards cloud services and the rapidly expanding number of networked devices and connections.”

In addition, the project will adhere to global engineering and sustainability standards, with measures to ensure low emissions. These include the selection of a DEME Group Living Stone vessel powered by dual-fuel capabilities for installation of the marine cable.

The vessel uses biodegradable grease and oil in addition to heat recuperation to decrease fuel consumption, as well as minimise carbon dioxide, nitrogen oxide and sulphur oxide emissions.

At the same time the cable will have a target burial depth of two to three metres below the surface of the seabed, providing enhanced protection and increased service availability.

“The Zeus subsea route represents not only the newest technology in equipment and installation but our dedication to responsible and sustainable infrastructure,” said Yannick Leboyer, chief operating officer of Zayo, Europe.

Marine operations for the project are due to begin in August of 2021 with a ready for service date set for by the end of Q1 2022.
