Deutsche Telekom (DT) launched the Access 4.0 program to introduce a disaggregated, automated platform for access and service edge in the next generation German fixed network – while preserving already installed equipment and services. Progress in the Access 4.0 platform development is ongoing, with first pilot deployments running stable and robust over time. By inserting VOLTHA between its existing Optical Line Terminals (OLTs) and upper‑layer OSS/BSS, DT created a vendor‑neutral environment that supports both in‑service hardware and new, white‑box platforms.
This case study explains why DT chose VOLTHA, how the solution was integrated, the benefits so far, and the operator’s forward path.
