Client Brief

With 7 subsea cable stations and 2 terrestrial backhaul networks into London and Slough, Linbrooke have been involved in works on all L3 sites in the UK – including the build of their new backhaul link into Slough, Lannion France and upgrading the Apollo Submarine system to Ciena Flexgrid.

Mainly working on the Subsea equipment for L3 Linbrooke have carried out over 20 upgrades over the last 2 years. This includes major new builds on dark fibre pairs increasing capacity on the L3 network.
