Tele Columbus Advocates for a Shift Away from DSL Technology

Sat 14th Jun, 2025

Tele Columbus, the Berlin-based company known for its Pÿur service, has expressed concerns regarding the Deutsche Telekom's reluctance to phase out DSL technology. As the demand for faster internet continues to rise, Tele Columbus argues that the transition to fiber-optic infrastructure is essential for both economic efficiency and future readiness.

In a recent blog post, the Deutsche Telekom emphasized that millions of households in Germany still rely on their DSL network for internet and telephone services. The company criticized claims that the copper network is nearing obsolescence, labeling such assertions as misinformation. Despite acknowledging the advantages of fiber-optic technology, Telekom stated that consumers ultimately have the choice, and a timeline for DSL discontinuation has not been established.

In contrast, Tele Columbus advocates for a definitive deadline for the switch from DSL to fiber. They assert that such a timeline would facilitate a smoother transition, allowing consumers and providers ample time to prepare for the new infrastructure. The company argues that maintaining dual systems is inefficient, and a clear cut-off date would expedite the rollout of gigabit-capable fiber networks into homes and businesses.

Tele Columbus also highlighted the financial benefits of upgrading from DSL to fiber optics. They noted that many households have been stuck with outdated DSL connections, missing out on current market prices and faster internet speeds. With fiber-optic connections offering speeds up to five times greater than DSL, consumers could save significant amounts on their internet expenses.

Market research indicates that the Deutsche Telekom has little incentive to deactivate its DSL network in areas where competitors are building fiber-optic infrastructure. The company is expected to retain DSL services until the user base drops below 20 percent, thus delaying the benefits of high-speed internet for many households.

Tele Columbus has called for a comprehensive strategy for transitioning from DSL to fiber that prioritizes competition and consumer interests. This call aligns with industry associations, emphasizing the need for a cohesive approach to ensure rapid and widespread fiber deployment, which would stimulate infrastructure investments and enhance consumer choice.

According to regulations, companies with significant market power, such as Deutsche Telekom, must notify the Federal Network Agency at least a year in advance before shutting down parts of their telecommunication networks. This notification should include a timeline and alternative access product descriptions.

Recently, the regulatory authority tempered expectations regarding the immediate shutdown of copper networks. They issued a discussion paper aimed at fostering constructive dialogue within the industry, emphasizing consensus and cooperation among market participants, though recent exchanges suggest this may be challenging.

Achim Wambach, president of the Center for European Economic Research, has underlined the necessity for a clear and consumer-focused plan for migrating from copper to fiber, including a realistic cutoff date for DSL. The European Commission has proposed a transition by 2030, but this timeline is viewed as overly ambitious by many stakeholders, including the Federal Network Agency, which has not set definitive deadlines. Telekom has claimed there is no external pressure from Brussels, noting that the Commission has only issued a discussion document.
