What is Dark Fiber?

Dark Fiber, i.e. unlit glass fibre, is a term for glass fibres that activating equipment has not yet been connected to. The activating equipment is needed to send and receive data through the glass fibre (fibre optics). In other words, without this activating equipment the fibre literally remains unlit, which is why it is known as ‘Dark Fiber’.

Dark Fiber means unlimited scalability

Relined provides unlit glass fibre (fibre optics) that you yourself must light up. You decide yourself which bandwidth you need for your own network or to provide to your customers. The possibilities are (almost) endless.

Advantages of Dark Fiber

The following table lists all the benefits that Dark Fiber can give you compared to a standard broadband service (Dark Fiber vs. wavelength):

Our own Dark Fiber network with WDM

Open and independent
Investing in improvements
Scalable up to 80 channels
Futureproof, high capacity (40 and 100 GE)
Requires specialist knowhow
All services on a single fibre
High performances; fibre pair completely self-managed and self-used
Completely transparent
Complete freedom to choose strategic and other service provision
Secure, 100% self-managed

Bandwidth service

Dependent on provider
Everything is regulated
Less scalable
Only futureproof to a limited extent
Saves on the specialist knowledge needed
Each service via a separate fibre
Unpredictable latency; network is shared with third parties
Limited transparency
Limited choice of service provision
Security dependent on service provider

Encryption and Dark Fiber

Leased connections and Dark Fiber glass fibres travel across public land, which means they can be ‘broken into’. Unlit glass fibres (Dark Fiber) are inherently more secure because you manage the peripheral equipment yourself. It is also possible to add another layer of protection (namely encryption) to the signal. This is an attractive option for such organisations as banks and hospitals that handle sensitive data.

Dark Fiber protection in each connection

By applying encryption directly in the WDM equipment, you protect per wavelength/colour i.e. per connection. Another advantage of encrypting at glass fibre-level is that there is less delay than with IP or other encryption at higher system levels or at the level of the application. Centralise your encryption key management by entrusting it to a single security officer so that this is kept separate from the network department and/or the server/application department. This can even be done separately for each encrypted connection at the associated organisation, department or business unit.

Who is Dark Fiber suitable for?

Dark Fiber is suitable for businesses that need a very stable, very reliable and very secure connection that is scalable too. Customers buy the transmission equipment themselves that meets their needs. Thanks to the never-ending scalability of Dark Fiber, you can set up and extend connections yourself that provide the desired services and bandwidth. You do not need to buy in any additional bandwidth to do this.

Our customers include not only data centers, network operators, ISPs, hosting parties and system integrators but also organisations in the corporate and healthcare sectors and government institutions.
