Aerial Fibre Deployment: Faster, Cheaper — If It Is Done Right
Underground fibre is durable but slow and expensive to build: trenching, road-cutting permissions and restoration take time. Aerial fibre — strung on utility or dedicated poles — can be deployed in a fraction of the time and cost, which is why it is widely used for campus links, last-mile networks and rural and semi-urban routes.
Choosing the right cable
- ADSS (all-dielectric self-supporting): no metal, so it can run near power lines and needs no messenger wire.
- Figure-8 cable: fibre with an integrated steel messenger for longer spans.
- Drop cables for the final connection into buildings.
What a good build involves
- Route survey: pole condition, spans, clearances over roads and existing cables.
- Permissions: pole-attachment agreements and local approvals.
- Engineering: sag and tension calculations for span length and wind load.
- Installation: correct hardware, slack loops at joints and clear labelling.
- Splicing and testing: fusion splicing in weatherproof closures, OTDR traces and loss measurements.
- Documentation: as-built maps with pole numbers and joint locations.
Maintenance matters more overhead
Aerial cables are exposed to storms, vehicles and construction. Regular patrolling, spare cable and fast restoration teams keep availability high.
