Continuing expansion of the fiber-optic network

Deutsche Telekom operates the largest fiber-optic network in Europe, covering a length of 500,000 kilometers in Germany alone. We are further expanding our fiber-optic network to keep pace with demand for higher bandwidths in the network. We use our online ticker to report on our progress.

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 infrastructure by means of super vectoring. With FTTH, the fiber-optic cables are taken right into the customer’s home.

Download up to 16 Mbit/s up to 250 Mbit/s up to 1,000 Mbit/s
Upload up to 2.4 Mbit/s up to 40 Mbit/s up to 500 Mbit/s

Super vectoring compensates for electromagnetic interference that arises between the copper lines on the way to the households. The technology allows for faster data transmission with speeds of up to 250 Mbit/s img. The technology for this is installed in the cable distribution box.
