Cable Maintenance & Repair


A-2-Sea maintains in excess of 80% of all the subsea optical telecommunication cable that lands in the UK, utilising its own qualified jointing products, comprehensive equipment and highly experienced jointers. A-2-Sea also maintains many of the UK’s inland subaqueous telecommunication cables, together with subsea optical telecoms cables in Europe and other international locations.

We offer an extensive 365/24/7 hotline and standby maintenance service in the UK which provides a rapid response to faults within the terminal station, beach landing, subsea cable and along the land route.
