Efficient Broadband Expansion: Time and Cost Advantages Through Modern Blowing Technology

Broadband expansion in Germany is a race against time. To provide households and businesses nationwide with high-speed internet, innovative methods are needed that accelerate the process while simultaneously minimizing costs. One of the key technologies we at EuroNordBau rely on is modern blowing technology.

In this blog post, you will learn why "blowing" fiber optic cables is far superior to conventional pulling and what economic advantages this offers for developers and municipalities.

2. What exactly is blowing technology?

With blowing technology, the fiber optic cable is not mechanically pulled through a conduit, but rather "pushed" or "carried" using compressed air. A special blowing machine guides the cable into the microduct, while a powerful compressor generates a constant airflow. The cable glides almost frictionlessly through the conduit on a cushion of air.

2.1. Protecting the Sensitive Fiber Optics
Unlike pulling, blowing into the fiber optic cable does not create dangerous tensile stresses. Since fiber optics are made of delicate quartz glass, this process-related protection of the fibers is essential for the longevity and signal quality of the network.

3. The Key Advantages: Focus on Time and Costs
The use of modern blowing equipment offers significant advantages that are revolutionizing broadband expansion:

Enormous Range: Blowing into the fiber optic cable allows cables to be laid in a single piece over distances of up to 2,000 meters. This eliminates the need for additional ducts and splice points.

High Speed: The process is many times faster than manual methods. This means shorter construction times and faster commissioning.

Minimal Personnel Costs: Because the system is highly automated, less personnel are required on-site, reducing the overall project costs.

Flexibility: Existing conduit networks can often be easily retrofitted without the need for new excavation work (trenches).

4. Technical Precision for the Highest Demands
At EuroNordBau, we use the latest generation of blowing systems. These devices continuously monitor the pressure and feed rate. Should an obstruction occur in the conduit, the device stops immediately to protect the fiber optic cable from kinking or damage.

4.1. Microducts and Jetting
This technology truly shines when installing micro cables in microducts (small empty conduits). This so-called "jetting" makes it possible to create additional capacity even in conduits that are already occupied.

5. FAQ: Essential Information on Blowing Technology in Broadband Expansion
Question 1: Why is blowing better than pulling?

Answer: When pulling, the entire force is concentrated on the beginning of the cable, which can lead to stretching. When blowing, the force is distributed evenly along the entire cable length, eliminating the risk of fiber breaks.

Question 2: What requirements must the empty conduits meet?

Answer: The pipes must be pressure-resistant, clean, and, above all, unobstructed. At EuroNordBau, we always perform a calibration and pressure test of the pipes before blowing them in.

Question 3: Does the blowing technique really save on excavation costs?

Answer: Yes, significantly! Because we can bridge greater distances without intermediate shafts, the need for complex earthworks and shaft construction is considerably reduced.

Question 4: How weather-dependent is the process?

Answer: Thanks to modern compressed air dryers, we can use the blowing technique almost year-round. Moisture in the air is filtered, preventing the cable from sticking to the pipe.
