Dark Fibre Definition

Dark Fibre means unlit fibre optics: fibre optics not connected to any active equipment. To generate a signal for the sending and receiving of data, optical equipment has to be connected to the fibres. Without this, the fibres remain unilluminated, or dark – hence: Dark Fibre.

Complete control and unlimited scalability

Relined provides your unlit fibre optics. These are not shared – and therefore secure – and offer you complete control, and so also complete freedom. You and only you determine what services you will transmit through the connection and how much bandwidth you will allocate to your network, or your customer’s. The bandwidth is unlimited and so are the possibilities. And because you retain total control, you can easily scale up as and when you or your customer needs to.

Advantages of Dark Fibre

Advantages of having your own dark fiber

  • Network is not shared with third parties
  • Scale based on your own connectivity needs (up to 80 channels)
  • All services on one fiber
  • Very safe because of your own lighting equipment

We guarantee you with dark fiber

  • Own dark fiber consisting of one fiber pair
  • Access to unlimited bandwidth
  • A private network which is not shared with third parties
  • Low latency


Unlit fibre optics (Dark Fibre) allow you to create an extremely secure network, as you control all the peripherals needed. You can also implement extra encryption (security) on the signal. An interesting option for banks, hospitals and other organisations working with sensitive data.

Need help setting up?

We often work with System Integrators setting up and managing the network. They are experts in all the technical aspects involved in connecting a broadband network

Who is it for?

Dark Fiber is perfect for companies with a need for a highly stable, reliable and secure connection, which is scalable. You acquire your own transmission equipment to suit your individual requirements.
