Broadband advance services/ FTTH connections

1&1 Drillisch AG is expanding its fibre optic offering and will in future receive all VDSL and FTTH advance services (fibre to the home - "FTTH") from its affiliate 1&1 Versatel. For this purpose, 1&1 Drillisch has entered into an agreement with 1&1 Versatel on the long-term purchase of FTTH and VDSL complete packages including Voice and IPTV effective from 1 April 2021.

At the same time, 1&1 Versatel has entered into an agreement with Deutsche Telekom on the use of Deutsche Telekom's FTTH / VDSL connections for households. These enable 1&1 Versatel to provide FTTH / VDSL complete packages for 1&1 Drillisch, as 1&1 Versatel's nationwide transport network is largely connected to the local broadband networks of Deutsche Telekom. The FTTH purchase from Deutsche Telekom has a term ten years.
