The brief
A four-tower IT campus needed to replace an ageing copper backbone without interrupting the 3,000 people working there.
What we did
- Laid 2 km of 48-core single-mode fibre through existing ducts
- Installed new core racks in each tower's comms room
- Ran the cut-over across three weekends, one tower at a time
Result
Backbone capacity went from 1 Gbps to 40 Gbps between buildings, with no working-hours downtime. Every core is labelled and documented in the handover pack.
