Zayo Group Holdings announced the deployment of a new high fiber count and  ultra-low-loss (ULL) subsea cable, "Zeus". The Zeus cable will run parallel but diverse to Zayo's existing Circe North subsea route, directly connecting the UK to mainland Europe via Lowestoft, UK and Zandvoort, Netherlands.

Zeus represents a substantial upgrade in capabilities, with a potential capacity of more than 4,000Tbps. Zeus will enable critical connectivity and next generation technology within this essential corridor for carriers, hyperscalers and large enterprises, all dependent on low-latency, low-loss and high capacity bandwidth connections.

The Zeus project adheres to world class engineering and sustainability standards, with measures to ensure low emissions. These measures include the selection of a DEME Group Living Stone vessel powered by dual-fuel capabilities for installation of the marine cable. Additionally, the vessel utilises 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.

Zayo is using Hexatronic's high-fibre-count cable for the Zeus project, which provides the latest generation of cable technology including high-capacity 192 fibre, 100% double armoured cable with increased crush resistance and ULL fibre technology. In addition to increased capacity, the cable will provide an unmatched level of resilience for the route.

According to the International Cable Protection Committee, 100 to 200 damaged subsea cables are reported annually, the majority of incidents caused by human activity, led by fishing. To mitigate impact of this activity, the cable will have a target burial depth of two to three metres below the surface of the sea bed, providing enhanced protection and increased service availability.

The Zeus diverse subsea system is owned and operated by Zayo. The commencement of marine operations will begin in August of 2021 and is anticipated to be operational by the end of the first quarter of 2022.
