German cable operator Kabel Deutschland (KDG) has announced it has expanded its high speed fibre-optic cable network to the cities of Bremen, Kiel and Magdeburg. A total of 570,000 households in the three cities and their surrounding communities will now be able to access broadband internet at maximum download speeds of 100Mbps. As previously reported by CommsUpdate, KDG implemented the DOCSIS 3.0 standard to boost its broadband download speeds to up to 100Mbps in February 2010. After implementation in Hamburg, Hannover and Munich in the second quarter of 2010, the company said the 100Mbps service would be rolled out to a further 14 cities – Augsburg, Berlin, Bremen, Dresden, Helmstedt, Kiel, Leipzig, Ludwigshafen, Magdeburg, Nauen, Nuremberg, Potsdam, Saarbrucken and Wurzburg – by the end of its current business year (31 March 2011). So far, KDG has upgraded around 80% of its connectable households for internet and telephone services. Through the further expansion, the 100Mbps service will be made available to 45% of upgraded households. Before summer 2012, KDG is hoping to deploy the high speed internet access across the whole of its upgraded network.
