Deutsche Telekom said it started offering the Internet with up to 100 Mbps and a minimum of 50 Mbps download and 40 Mbps upload speed to 200,000 more households in 209 cities and communities in Germany.

“Some of our upgrade projects serve tens of thousands of households, while others serve just a handful. For us, every line counts whether they are in big cities like Berlin, Erfurt or Nuremberg, or in small towns like Hirschaid, Kranenburg or Stutensee,” Tim Hottges, CEO of Deutsche Telekom, said.

Deutsche Telekom engineers have replaced the copper lines running between local exchanges and street cabinets with fiber-optic cables (FTTC) to support higher transmission speeds. The engineers are converting existing large, gray roadside distribution cabinets into multi-function cabinets.

In the multi-function cabinets, the light signal coming from the fiber-optic line is converted into an electrical signal, and then fed into the existing copper cable leading to the subscriber’s access, Deutsche Telekom said.

Deutsche Telekom engineers are utilizing the vectoring technology in order to make that copper-cable connection fast. Vectoring technology, by reducing electromagnetic interference in lines, boosts bandwidth significantly to ensure better customer experience to broadband customers. Deutsche Telekom will be using super-vectoring technology to enable bandwidths of up to 250 Mbit/s from the second half of 2018.
