Fresh on the heels of certifying the first gigabit-capable, DOCSIS 3.1 modems, CableLabs says it’s exploring dramatically boosting cable broadband’s upstream speeds and providing symmetrical connections up to 10 Gbps. While eventually DOCSIS 3.1 devices are expected to support speeds of 10 Gbps downstream and 1 Gbps upstream, the first wave of devices just hitting the market will “only” support 5 Gbps downstream and 1 Gbps upstream.
