Dark Fibre

Unlit fibre with unlimited potential

What is Dark Fibre?

A dark or ‘unlit’ fibre refers to unused fibre optic cable in the ground. Laying fibre routes requires substantial investment, so cables are installed with extra capacity available for lease. Dark fibre gives you complete control over your network infrastructure.

Benefits of Dark Fibre

Scalability

Maximum control and network flexibility. Expand your network as bandwidth demands increase, with virtually limitless capacity. No dependency on your provider’s equipment or protocols.

Security & Privacy

Networks are physically dedicated to your organisation and remain unshared. This offers complete confidentiality and helps demonstrate regulatory compliance for data protection requirements.

Route Diversity

Network route diversity protects against outages. Design geographically diverse Dark Fibre networks separate from existing routes, or establish secondary backup paths for resilience.
