Full control. Maximum security. Lowest latency.
Site Connectivity with Dark Fiber
Dark fiber (also known as “darkfibre”) is a fiber optic cable without an active infrastructure. It is therefore sold or leased unconnected or without light on it (dark). The fiber optic cable is spliced through point to point between two locations.
The customer is responsible for selecting, operating and updating the optical components, which is why the bandwidths and possible protocols can also be selected by the customer. The costs of the line therefore do not depend on the speed used.
The advantages of Dark Fiber in a nutshell:
- Scalability: The bandwidth can be flexibly increased at any time without having to replace expensive routers.
- High security: Data transmission via dedicated lines, logical separation of the network ensures security at the infrastructure level.
- Simple connection: Connection of local networks via Ethernet interface, without additional routers. Flexible bandwidth adjustment without additional investment in hardware.

Features of a Dark Fiber
Flexible network topologies
Various structures such as ring, star or cascade networks enable an optimum connection depending on the location and redundancy requirements.
Full control
Selection, operation and updates of the optical components are entirely up to the company. Bandwidths and protocols can be freely defined.
Redundancy
Existing reserve fibers in the cables can be connected if required, thus increasing reliability.
Independent scalability
Bandwidths can be flexibly increased at any time – independent of providers or fixed tariff models.
Maximum security
Dedicated lines with logical separation ensure maximum security, as there is no external use.
Lowest latency
Ideal for SAN couplings, metro storage or other latency-sensitive scenarios.
Network configuration options with Dark Fiber:
1
Ring network
The ring network resembles a string of pearls. The pearls represent the locations. Locations that are geographically close to each other can thus be efficiently connected to form a network.
2
Star network
The Star network is a point-to-point connection in which each location is connected to the central main point. This network connection is used for geographically distributed locations. This network variant is more expensive to cover the greater distances between the locations.
3
Cascade network
When locations are connected one after the other in a series, this is referred to as a cascade network. This is a non-closed connection that is more efficient in terms of costs and length of connection.

Dark fiber provider
Finding the right provider for your dark fiber solution is not easy. As different as your requirements and wishes are, as different are the offers of the individual providers.
What is important:
- Location of the sites and routing
- Availability in the city or (wide-area) area
- Matching topology with ring, star or cascade
- Responsibility for optical components and operation
- Need for guaranteed service levels and provision times

Dark fiber: responsibility, redundancy and areas of application
When purchasing dark fiber products, you are responsible for securing the transmission and managing the transmission devices yourself. The bandwidth used on the line itself must also be determined. This is done, among other things, via the different color spectra used on a fiber optic cable.
The cables contain redundant fibers to absorb any physical interference on the cables. The unused fiber optic capacity in the cables is also referred to as dark fiber, as no light signals are transmitted when the fibers are unused and the fiber is therefore “dark”. The existing redundancy means that additional fibers can be put into operation if required.
Dark fiber is offered by various carriers in both the city and wide area. In addition to operating its own private data networks, it is also often used to link SANs (storage area networks) or in metro storage in order to achieve the lowest latency times (low latency).
