Streaming videos stutter at the most crucial moments; remote workers lose their connection during important conferences — a stable internet connection is more important than ever. The solution for reliable connectivity is fiber optic technology. Matthias Lehniger, Business Area Lead for Fixed & Mobile Networks at Axians Germany, explains in this article which advantages this technology offers and why investing in it pays off in the long run.

The German federal government’s goal of achieving nationwide fiber-optic expansion by 2030 is currently at risk, as I already outlined in my previous article, “Nationwide Fiber-Optic Expansion by 2030: How This Vision Can Become Reality.” While the number of connected households is rising, the activation rate — meaning actual usage of the connections (Homes Activated) — lags significantly behind: According to a recent study by EY conducted in collaboration with Deutsche Telekom, only 28 percent of households with access to fiber-optic internet are actively using their connection.

At the same time, many users remain satisfied with the data transfer speeds of their current DSL or copper connections. Yet this comfort is deceptive: Germany’s data demand doubles every three years! It’s already evident that copper cables and other older technologies will not be able to keep up with this growth over the long term. This trend makes the switch to fiber optics inevitable. The technology brings numerous advantages that make it the superior alternative:

Speed

With a fiber-optic connection, users surf at impressive speeds of up to one gigabit per second (Gbit/s). This means data flows with virtually no delay, videos load in an instant, and even large files are downloaded in no time. Buffering is finally a thing of the past with fiber optics.

To illustrate its performance: Fiber optics can transmit ten times more data than a conventional VDSL line with 100 Mbit/s. This difference isn’t just visible in numbers — it’s clearly felt in everyday use. Whether streaming in UHD, online gaming, cloud applications, or video conferencing — fiber optics ensures a consistently stable connection.

Reliability

Fiber optics stands for reliability. Unlike traditional copper cables, it transmits data not electrically, but via light waves. This makes it immune to electromagnetic interference caused by electronic devices or power lines. The result: a connection that remains stable even under demanding environmental conditions.

Additionally, fiber-optic cables are highly resistant to weather. Made of glass or plastic fibers, they are less susceptible to external influences such as temperature fluctuations, moisture, intense UV radiation, or extreme weather. Whether during storms, freezing cold, or scorching summer heat — fiber optics stays operational and guarantees reliable connectivity. For users, this means no sudden dropouts during critical video calls, no speed drops while gaming online, and no interruptions while streaming — even under the harshest weather conditions.

Sustainability

Fiber-optic technology is not only powerful and reliable, but also environmentally friendly. Fiber requires significantly less energy to transmit data. The efficient use of light waves substantially reduces energy consumption, thereby contributing to a noticeable reduction in CO₂ emissions.

Another advantage: Fiber optics produces no electromagnetic radiation, which can be both disruptive and energy-intensive. This makes fiber optics a greener alternative, playing an important role in climate protection — especially at a time of ever-increasing data volumes.

High Capacity

At peak time, 8:15 PM, some residents in the same apartment building are streaming live TV, while others are watching a movie, browsing online, downloading large files, or joining video calls. With a conventional connection, this could quickly lead to bottlenecks. But with fibre optics, the connection stays fast and stable—no matter how many devices are in use at once.

Thanks to the high transmission capacity of fibre-optic technology, multiple users can run data-heavy applications simultaneously without any drop in speed. Whether it’s ultra-HD streaming, cloud backups, or online gaming, fibre handles peak loads effortlessly. This performance makes it the ideal solution for households and businesses with demanding connectivity needs.

Future-Proof

Fibre-optic technology isn’t just a solution for today’s needs—it’s built for the digital challenges of tomorrow. Its performance already surpasses all other transmission media, and its data capacity will remain unmatched for decades to come.

An active fibre connection is both an immediate upgrade over existing technologies and a long-term investment in your internet access. As data demands grow and digital applications evolve, fibre is ready to meet future requirements with ease. At the same time, a fibre connection boosts property value, as fast and reliable internet is increasingly seen as a basic feature of modern homes and workspaces.
