Continuing expansion of the fiber-optic network

Telekom already operates the largest fiber-optic network in Europe with a length of 455,000 kilometers. However, demand for higher bandwidths is constantly increasing. In view of this trend, we continue to expand our fiber-optic network in order to secure our business success in the long term. Our goal is to provide 80 percent of Germany's population with a minimum of 50 Mbit/s img by 2018/2019 – subject to regulatory changes.

To reach this goal, we are using FTTC img (fiber to the curb) technology and are expanding FTTH img (fiber to the home) as well. In the scope of the FTTC expansion, fiber optics are laid to the gray street cabinets on the curb. From there we can supply our customers with large bandwidths via existing lines by means of VDSL img vectoring. With FTTH, the fiber-optic cables are really taken into the customer’s home.

Download up to 16 Mbit/s up to 100 Mbit/s up to 200 Mbit/s
Upload up to 2.4 Mbit/s up to 40 Mbit/s up to 100 Mbit/s

Vectoring img compensates for electromagnetic interference that arises between the copper lines on the way to the customer's home. The technology allows for faster data transmission with speeds of up to 100 Mbit/s. The technology for this is installed in cable distribution boxes.

In October 2017, we switched the first two of 7,600 nearshore areas in Germany to fast vectoring: Moitin near Rostock and Bad Grund in the Harz region. Nearshore areas are households that are supplied over street cabinets at a distance of at most 550 meters from the main distribution frame (the central service installation for households and companies in the area). The German Federal Network Agency decided in 2016 to approve vectoring expansion in the vicinity of Deutsche Telekom's main distribution frames (nearshore vectoring).
