CeltixConnect - The shortest, most secure system crossing the Irish Sea

Points of Presence

The CeltixConnect cable system was installed by Global Marine Services Ltd in the latter half of 2011 following two years for permitting, survey and detailed design.

The cable system was designed to provide the shortest, but most secure cross of the Irish Sea. Its landfall at Clontarf in Dublin provides one of the safest landfalls on the east coast, located within kilometres of the city centre with connection to Dublin Metro fibre providers at the CLS in East Point Business Park. 

The sub-sea routing from Clontarf avoids fishing and shipping areas as well as mobile sand wave fields to the south whilst providing in excess of 1m of burial in stable stratum throughout. On the difficult approaches to Holyhead the cable utilises double armour and rock armour as well as following the exact route corridor of the highly reliable BT-TE1 cable which was in existence from 1981 to the early 2000s with no outages. The cable system connects into the new Welsh Government Fibrespeed network across North Wales to tie into all of the UK Backhaul providers at Deeside, Manchester and Stoke.

We offer Bandwith, Dark Fibre and Spectrum services on the CeltixConnect system.
