While Docsis vendors work on refreshing the technology to reach 10Gbit/s downstream speeds, a recent field trial shows that current gear can get almost halfway there.
Ahead of next week’s ANGA Cable Show in Cologne, Kabel Deutschland GmbH and Arris Group Inc. (Nasdaq: ARRS) demonstrated downstream speeds of 4.7Gbit/s on live Docsis 3.0 plant connected to a school in Schwerin, Germany.
It’s considered a new Docsis land speed record, achieved by bonding 96 8MHz-wide EuroDocsis channels (that’s 768MHz total spectrum). The trial used 12 Arris cable modems, each capable of bonding eight downstream channels (the latest generation of Docsis 3.0 modems can bond up to 24).
