Maximum Control and Speed with our Dark Fiber Service
Your custom fiber optic solution for ultimate performance and data security for business critical networks. Scalable to meet future demands without additional infrastructure costs. Supports bandwidths of several TBit/s.
Why Dark Fiber?
Dark fiber, also known as unlit fiber or dark fibre, refers to fiber optic cables that are not currently in use. Companies lease or purchase these cables to run their own networks, providing complete control over their network infrastructure. This level of control results in maximum flexibility, enhanced security, and superior performance.
As IT continues to converge within data centers and bandwidth demands surge, the strain on your network intensifies. To overcome these challenges, many companies are now integrating dark fiber into their network architecture.
A dark fiber network offers a reliable and secure optical infrastructure, enabling businesses to manage critical aspects of their network independently. It provides unparalleled flexibility and control, allowing virtually limitless bandwidth expansion exactly when and as quickly as needed. By adopting dark fiber, businesses can effectively meet growing network demands and ensure their infrastructure remains future-proof.
For businesses that need to transmit large amounts of data, such as data centers, financial institutions, media companies, or cloud providers, Dark Fiber offers an unbeatable solution. It is especially attractive for companies that:
- Have high bandwidth requirements
- Require the highest data security standards
- Want to control and customize their own network infrastructure

Frequently Asked Questions
What is a dark fiber connection?
Dark fiber refers to an unlit fiber optic line provided for your exclusive use. You bring your own transmission equipment and use the full capacity of the connection.
Why should businesses rent dedicated fiber instead of buying it?
Renting fiber avoids high upfront investments while giving you full control over performance, hardware and security. You are also independent of provider infrastructure.
How does a dark fiber connection work technically?
You receive access to the physical fiber only. Your team handles the transmission layer using modules like SFP or QSFP and protocols like DWDM or CWDM.
Is dedicated fiber GDPR-compliant?
Yes, because you manage encryption, routing and data handling yourself. This makes it easy to meet the highest compliance and data protection standards.
What types of businesses benefit from dark fiber?
Any organization with high data volumes or strict security requirements, such as enterprises in manufacturing, cloud hosting, media or research.
What bandwidths are possible with dark fiber?
Bandwidth is only limited by your equipment. Depending on your setup, speeds of 10 Gbps, 100 Gbps or more are achievable.
What does dedicated fiber in Germany cost?
Pricing depends on distance, buildout requirements, SLAs and contract duration. We provide tailored quotes for each project.
How long does provisioning take?
Depending on the availability of routes and construction needs, provisioning typically takes a few weeks to several months.
Can multiple sites be connected with dark fiber?
Yes, we support flexible designs including point-to-point, ring or mesh topologies with guaranteed latency and failover options.
Are redundant connections available?
Absolutely. We provide fully redundant designs with separate routes and active monitoring for maximum availability and network resilience.
