Kabel Deutschland achieves 4.7Gbps download speed

Germany’s Kabel Deutschland says it has become the first cable operator in the world to successfully achieve a download speed of 4.7Gbps in a field test via the cable network. According to a company press release, the tests took place at a school in the city of Schwerin over an 862MHz upgraded cable network. They were carried out in co-operation with technology firm ARRIS, which supplied a head-end using a standard commercial EuroDOCSIS 3.0-based ARRIS C4 CMTS (Cable Modem Termination System) and twelve Touchstone CM820S cable modems. ‘Our field test with a download speed of significantly more than 4Gbps was a complete success and underlines once more the possibilities of a cable network as the only extensive ultra-broadband network in the German broadband market,’ commented Lorenz Glatz, CTO of Kabel Deutschland. The achievement comes on the back of an announcement last week by Croatian cellco VIPnet (owner of the country’s largest cableco B.net), which claimed it had demonstrated a peak speed of 4.3Gbps during data transmission tests on its DOCSIS 3.0-based HFC cable network.
