Broadband expansion

The network expansion is carried out by the telecommunications companies themselves. The city of Jena only coordinates within the scope of its legal responsibilities - for example by issuing excavation permits or traffic regulations.

The respective network operator - not the city of Jena.

The city of Jena does not assume any expansion costs, except in the area covered by the so-called "Weiße-Flecken-Programm".

Because a later expansion can be more expensive and complex. In addition, fiber optics are future-proof and increase property value.

Not because of pure speed, but because of higher service quality, including

• Higher network stability

• Low latency times

• Future-proof (copper networks are considered to be exhausted and prone to faults)

In this case, your property will not be connected - but a subsequent connection remains possible.

Deutsche Telekom:
Own-account expansion of existing network throughout the city. Target: 51,000 households by 2028

Thüringer Netkom:
Subsidized new network construction of individual peripheral locations, 446 households and commercial units by the end of 2026.

OXG Glasfaser GmbH:
Self-financed new network construction since 2025, target: approx. 40,000 homes by the end of 2027.

Kommunalservice Jena (KSJ) provides information on the current status of broadband expansion on its website. It is currently not possible to allocate specific time windows for individual addresses. This detailed information is not available to the municipal authorities as it is controlled by the telecommunications companies. If you would like to know whether your connection is already being marketed, it is also worth asking your telecommunications provider directly.

Yes, as long as the representatives can clearly identify themselves as employees of Deutsche Telekom, Thüringer Netkom or OXG and it is only about your home connection. Don't let them put you under pressure, you can usually book a suitable Internet tariff at a later date. Make sure that your desired provider is also available on the respective network.

Not necessarily. All active network operators pursue a so-called open access approach. This means that various tariff providers can offer their services on these networks - but only if corresponding contracts exist between the network operator and the Internet provider.

In the available tariffs and partners. Although they all follow the open access principle, not every service provider (e.g. T-Online) will be available on every fiber optic network.

Some providers link the connection to a product booking. Those who book early are given priority connection. Without a product booking, the connection can be delayed or made up for at an additional cost.

Technically yes, but rarely practical. Fiber optic cables have to be laid right into the home - multiple lines mean more space is required and more work.

Yes, this is generally possible in existing residential areas. In new construction areas, a new extension may be necessary.

A free-of-charge agreement with the property owner giving the grid operator permission to enter the property and lay a connection. Also known as an "owner's declaration" or "permission". There is no obligation to connect.

No.

Some providers make expansion dependent on reaching a certain number of pre-contracts. No provider in Jena currently uses this model.

The road construction authority (KSJ) monitors the work and checks the quality of the restoration.

Due to the legally regulated free competition in the telecommunications market (TKG).

The respective network operator is responsible. Only in exceptional cases does the KSJ take over the restoration - then on the basis of a cooperation agreement.

Sections of 50-100 meters per week are common. House connections are usually installed separately and at specific points.

Please get in touch directly with the contact person of the company carrying out the work named on the mailshots . If your problem cannot be solved in this way, please send an e-mail to breitbandausbau@jena.de.

This cannot always be avoided - especially if parallel media installations are required.

Ask your landlord or get information from your preferred operator.

Kommunalservice Jena (KSJ) as the road construction authority.

Usually not. The work is carried out as one-day construction sites without major closures. Any restrictions will be agreed with you or your property management beforehand.

Yes, for reasons of competition law, it is not possible to allocate expansion areas exclusively to individual telecommunications companies. Compare both offers and choose the product that suits you best. Make sure that your preferred service provider is available on the respective network. If necessary, make use of your right of withdrawal.

If your questions remain unanswered, you can also contact us by e-mail at breitbandausbau@jena.de.

Don't make a hasty decision. Reputable sales staff will not put you under pressure and will be happy to come back. Claims that serve to revise the decision you have already made and urge you to make a quick decision are just as dubious as exclusive legitimization by a higher authority, e.g. the city of Jena.

Ask to see the employee's ID and make a note of the date and name. We will be happy to forward justified complaints to the responsible companies.

If you are part of a homeowners' association (WEG), the fiber optic connection in the building cannot simply be ordered individually. A joint resolution of the owners' association is always required to lay the lines within the building. One point is particularly important for your owners' meeting: legally, several telecommunications companies are allowed to lay their own lines in the building at the same time. In Jena, Deutsche Telekom, OXG / Vodafone and Thüringer Netkom are currently active, among others. This can mean in practice: Without a clear definition, different providers could gradually lay their own cables in the stairwell - with corresponding expense and multiple construction works.
