SUWANEE, Ga. — ARRIS Group Inc. (Nasdaq: ARRS) today announced that Kabel Deutschland (KD), Germany’s largest cable service provider, has successfully field tested the combination of a EuroDOCSIS™ 3.0-based ARRIS C4® CMTS and 12 ARRIS Touchstone® Cable Modem CM820S’ — each accessing eight bonded Annex A (8 MHz) channels — to deliver 4.7 Gbit/s of aggregated data throughput in the downstream. The tests were conducted on a real cable plant at a school in the city of Schwerin, Germany. Schwerin’s cable plant was recently upgraded by KD to 862 MHz, and the 4.7 Gbit/s field test was based on the use of currently available standards, technology and hardware. Kabel Deutschland has been an ARRIS CMTS customer since 2007.

“Our field test with ARRIS, with an aggregate download capacity of well over 4 Gbit/s, was a complete success and underlines the unique selling proposition of our cable network as the only extensive ultra-fast network in the German broadband market,” said KD Chief Technology Officer Lorenz Glatz. “Using this technology, a feature length movie could theoretically be downloaded in 8 seconds – at speeds faster than a standard laptop or modem can even process – demonstrating that today’s broadband cable network is already a high performance and sustainable infrastructure offering huge untapped potential.”

“This demonstrates that today’s HFC plant has the capacity to deliver a full IP video load, and that the entire HFC plant can be converted into one or more enormous pipes to meet future consumer bandwidth demands, using current technology and networks,” noted Tom Cloonan, ARRIS CTO, Network Solutions. “We congratulate Kabel Deutschland on pushing through existing barriers to deliver their customers the services of tomorrow, today.”
