TKG Amendment 2026 and Gigabit Infrastructure Ordinance: How New Access Rules Change Fiber Investments for Medium-Sized Businesses

8 Min. Reading Time · As of: 23.04.2026

In spring 2026, the regulatory framework for fiber-optic expansion in Germany is being reorganized. The Federal Ministry for Digital Affairs and Administrative Modernization has submitted the draft bill for the 2026 TKG amendment. The Federal Network Agency is working in parallel on a migration strategy for copper decommissioning. Additionally, there is the adaptation to the EU Gigabit Infrastructure Regulation 2024/1309. For German medium-sized businesses, this means an important change: fiber investments in business parks, industrial sites, and office corridors will receive a new set of rules in 2026.

What specifically changes in the TKG and why it affects medium-sized businesses

What is the TKG Amendment 2026? The TKG Amendment 2026 is a draft bill presented by the Federal Ministry for Digital Affairs and Administrative Modernization in spring 2026 to amend the Telecommunications Act. It adapts German law to the EU Gigabit Infrastructure Regulation 2024/1309, accelerates approval procedures for fiber-optic and mobile network expansion, establishes the Gigabit Register in law, and introduces new access regulations, such as Section 22a TKG-E for non-subsidized fiber-optic networks in areas with only one network operator. It is currently undergoing a consultation with associations and states.

The amendment is not a one-off intervention, but a fundamental regulation for the next decade of fiber-optic investments. Three main directions can be identified. Firstly: acceleration. Permit procedures for civil engineering and laying are streamlined, and a new notification procedure replaces some classic approvals. Secondly: data clarity. The Gigabit Register becomes a binding map that records networks, availability, and expansion plans. Investors will have a reliable nationwide view of infrastructure for the first time. Thirdly: access rules. Section 22a TKG-E forces network operators in monopoly areas to offer open access conditions, giving the BNetzA significant scope for design.

For medium-sized businesses in industry, logistics, and commercial centers, this mix is relevant because location decisions become more transparent. When planning connections for a new hall, logistics center, or commercial park, companies often had to negotiate with different carriers for months. With the Gigabit Register and Section 22a, the map becomes clearer, and the negotiating position improves. If a company experienced connection problems in the last two years, it should check in 2026 whether the new legal situation brings better conditions or new providers into play.

Specific use cases in medium-sized businesses that will benefit in 2026

Four application classes will benefit noticeably. The first is site development. Anyone planning an industrial area or digitizing an existing commercial park can now tender with several carriers in parallel and compare conditions in 2026, as the Gigabit Registry makes the starting situation transparent. For non-funded routes, § 22a facilitates the shared use of passive infrastructure, which reduces the double laying of empty pipes. Sites can thus be opened up more cheaply.

The second class is migration from old connections. Anyone still using DSL connections in subsidiaries, branch offices, or backup paths should plan the transition structurally in 2026. The BNetzA strategy for copper shutdown varies regionally, but an FTTH quota of 80 percent in an expansion region can now be initiated by carriers other than Telekom. Branch offices in regions with high fiber-optic coverage must prepare for the change in the short term, otherwise they will be left without a connection.

The third class is the multiple connection of critical locations. Logistics hubs, cloud on-premise setups, and smart factory locations require redundant connections with different routes. Open access on NE3 facilitates multiple commissioning, as a single physical network is open to several providers. Resilience is thus not only more expensive, but also realistically achievable. A site operator can conclude two contracts with different carriers, both of which are based on the same fiber-optic network but deliver different SLAs and routing.

The fourth class is Data Act-compliant IoT connection. Industrial sensors, logistics tracking, and energy management require reliable, low-latency connections with verifiable data residency. Fiber-optic islands in commercial parks form the basis here. Anyone planning the IoT rollout for 2027 should prioritize the connection question over the sensor investment, as connection delivery times vary regionally.

A practical 12-month roadmap for IT and site managers

Those who want to set up properly by 2026 work along a clear twelve-month plan. The plan covers inventory, contract analysis, negotiation, and migration. It suits medium-sized industrial companies, logistics operators, and site developers.

What the amendment means structurally for location development and management

The TKG amendment and adaptation to EU requirements are not just a tech issue, but a location issue. For those investing in logistics, production, or office clusters in 2026, the negotiation basis with municipalities, carriers, and construction companies suddenly changes. The discussion about fiber-optic connections must be included early in construction planning, rental agreements, and funding applications. Anyone writing a location concept without a connection strategy is calculating with assumptions that will noticeably shift by 2027.

For management, there is a second lever. Multi-year carrier contracts with unupdated migration clauses will become a potential trap in 2026. Those who concluded a 5-year DSL-based contract in 2024 will have to check in 2026 whether the migration option to fiber-optic is included in the contract or if renegotiation is necessary. The regional effects of the BNetzA copper shutdown triggers vary by state, so a nationwide location inventory is less of an end in itself than a control instrument.

For medium-sized investors in commercial parks and industrial areas, the amendment opens up new scope. Open access to non-funded fiber-optic networks allows for the construction of its own FTTB infrastructure and opening it to several carriers for marketing. This significantly changes the economic calculation for owners of commercial areas. Those who previously waited two or three years for a carrier can make the location more attractive in 2026 with its own fiber-optic island and amortize investments over several rental cycles.

An additional strategic factor is the Reboot Germany funds that will flow into infrastructure and location development in 2026. Those who conduct funding eligibility checks and economic analyses should incorporate regulatory changes into their argumentation. Funding approvals are granted faster if locations are applied for with a transparent connection strategy and verifiable migration planning. Those who do not do this systematically will leave funding quotas unused.

A final observation belongs on the management agenda. The shortage of skilled workers in fiber-optic construction will continue to be a bottleneck in 2026. Even accelerated approval procedures are of little help if no construction teams are available. Those who conclude framework contracts with civil engineering partners and fiber-optic specialists early on secure delivery slots that will remain scarce over the next two years. Medium-sized businesses that underpin their location planning with concrete construction slots will achieve productive connectivity faster in 2027 than competitors who are still stuck in approval loops.

How Fiber Optic Strategy Intertwines with Other Regulatory Topics

In 2026, fiber optic topics rarely stand alone. They are intertwined with three other regulatory topics that are running in parallel in the mid-market. The first is the smart meter obligation and the Energy Measurement System Act, which creates data-technical prerequisites in many industrial locations that in turn build on fiber optic connections. The second is NIS2 with its requirement for reliable availability of critical network components, which makes redundant fiber optic connections more attractive. The third is the Data Act, which regulates data transport between devices and platforms and thus indirectly drives latency and availability requirements.

Those who think about these three topics together are building a location strategy that addresses several compliance obligations simultaneously. For the IT management in the mid-market, this means an honest inventory of which regulatory topics drive which connection requirements. A joint strategic roadmap that brings together the TKG amendment, NIS2 resilience, smart meter backbone, and Data Act-compliant data paths in a consistent picture avoids expensive double investments and creates a basis for argumentation vis-à-vis management and the supervisory board.

A practical tip from consulting practice: Locations that have so far flown under the radar because they did not need a prominent connection are coming into focus in 2026. Branch offices with pure DSL connections, warehouses with only a narrowband mobile backup, and production offices with old and slow copper connections should be included in the central connection inventory. The migration is often not expensive, but it needs a guiding hand. Those who leave this inventory lying and do not actively deal with the upcoming migration will have a tangible availability problem on their hands in 2027 as soon as the regional copper shutdown takes effect and subsidiaries are left without a viable connection overnight.

The last point for the executive level: In 2026, fiber optic investments are no longer a pure IT issue, but a location and personnel issue. Employees expect reliable connections without waiting times in modern office buildings and plants. Recruiting and employee retention benefit from locations that do not stand out due to poor connections. Those who include this in the location argumentation have a soft factor that has a harder impact on HR decisions than most tech arguments. The HR managers in the company react to such arguments from experience much faster than IT strategists, because they work daily with applicant feedback and employee retention data and know concrete examples from their own recruiting everyday life.
