M-net: Munich has 500,000 households on the fiber-optic network


With the connection of the GWG Munich building on the Kainzenbadstraße in Munich, 500,000 households and businesses are connected to the fiber-optic network of M-net. That was the company known on August 13, 2019, Stadtwerke München (SWM) and its communications subsidiary M-net are mainly expanding FTTB (Fiber To The Building). The number of FTTH households (Fiber To The Home) of M-net in the core area of ​​Munich, Augsburg and Erlangen amounts to around 10,000, the company announced in October 2017.

SWM and M-net are gradually expanding the network. They started in the city center and the inner city peripheral areas. Since 2016, expansion outside the Mittlerer Ring has continued.
Florian Bieberbach, Chairman of the SWM Executive Board, said: "While others are still talking, we have been opening up Munich with fiber optics for over ten years, which makes us proud."

The next development areas are located in the eastern Pasing, in southern Nymphenburg, on the old heath and in Old Moosach. For the fiber-optic expansion, up to 50 civil engineering columns are on the way each year. A total of around 500 people are deployed by SWM and the contracted companies for grid expansion.

FTTB is not yet the optimal solution for the provider. Nelson Killius, CEO of M-net, said on May 28, 2019: "I'm not saying that FTTB is the best." M-net will, if it somehow go, only make FTTH expansion.

Nevertheless, one will still have to live with FTTB for 10 to 20 years, announced Killius. G.fast is used where the glass fiber only reaches into the cellar. The transmission method G.fast uses a frequency range for signal transmission in which vectoring and super vectoring overlap. A special feature is that G.fast Upstream and Downstream are freely scalable. 1 GBit / s is the sum bandwidth of G.fast, which can be split up to 400 MBit / s in the upload and 600 MBit / s in the download, for example.
