Der nächste Meilenstein im Ausbau der Breitbandversorgung heißt Fiber-To-The-Distribution Point (FTTdp). Hierbei wird die Glasfaser bis zu einem flexibel platzierbaren Verteilerkasten (Distribution Point / DP) auf relativ kurze Distanz an das Gebäude geführt. Für die Reststrecke zu und in Gebäuden wird die bestehende Kupferverkabelung genutzt. Wie sich in diesem hybriden Netz Datenraten von 1-2 Gbit/s real umsetzen lassen, untersuchen Wissenschaftler des Fraunhofer ESK zusammen mit Lantiq und der InnoRoute GmbH bis 2016 im Forschungsprojekt FlexDP.
Um hohe Datenraten zu erzielen, müssen über symmetrische Kupferleitungen auch hohe Frequenzbereiche genutzt werden.
