Fibre vs Copper Cabling for Commercial Sites
Most commercial sites use a mix of copper and fibre cabling. Copper is commonly used for work area outlets, access points, phones, printers and security devices. Fibre is commonly used for backbones, longer links and higher-capacity connections.
This guide explains how to think about fibre and copper cabling during commercial site planning.
Where each cabling type fits
- Copper for outlets and devices
- Fibre for backbone links
- Comms rooms and racks
- Distance and pathway constraints
- Future network capacity
Copper and fibre do different jobs
The right choice depends on distance, network design, device type, bandwidth requirements and future flexibility.
Copper cabling
Copper cabling is commonly used for desks, printers, WiFi access points, phones, cameras, access control devices and general local network outlets.
Fibre cabling
Fibre cabling is commonly used for building backbones, longer runs, high-capacity links, comms room interconnections and network expansion.
Comms racks
Both fibre and copper need to be planned around rack locations, patching, switches, cable management and future capacity.
Distance planning
Longer distances or links between areas may make fibre the better pathway, while local device connections often remain copper.
Future upgrades
Fibre can help support future network capacity where the site needs room to grow.
Coordination
The decision should be coordinated with the IT provider, building layout, site pathways and intended use of the space.
Think about the network before the cable is installed
Cabling choices should support the network design, not the other way around.
The site layout, rack positions, access point locations, camera locations and future expansion plan all affect whether copper, fibre or both should be installed.
EDN can work with the client and IT provider to install the physical cabling infrastructure required for the final network design.
Review before deciding
- Distance between racks and zones
- Switch and patching locations
- Access point layout
- Camera and security device locations
- Future expansion needs
- Testing and documentation requirements
Where fibre and copper are often used together
Most commercial networks are not purely one or the other.
Office fitouts
Copper often serves desks, meeting rooms and access points, while fibre may support building backbone or rack links.
Warehouses
Copper may serve local devices and cameras, while fibre can help link distant warehouse zones or separate communications areas.
Retail sites
Copper is common for POS, access points and cameras, while fibre may be relevant for larger sites or building infrastructure.

Is fibre always better than copper?
No. Fibre and copper do different jobs. The right choice depends on the site, device types, distances and network design.
Can EDN install both fibre and copper cabling?
Yes. EDN supports commercial data cabling and fibre infrastructure projects.
Who should decide between fibre and copper?
The decision should be made with the client, IT provider and cabling contractor based on the site requirements.
Does fibre need testing?
Fibre work should be tested and documented according to the project requirements and scope.
