Tech utilized three prototype modems
Cisco has demonstrated a DOCSIS 3.0-based system running in excess of 1.5 Gigabits per second (Gbps), with a 48-channel downstream connection. The achievement, which was demonstrated at CableLabs Winter Conference, required three of Cisco's prototype cable modes, each running 16 download channels and four upload channels.
"What we were going for was bolstering everybody's confidence in what we can do with DOCSIS," said Access Transport and Technology Group CTO John Chapman, as quoted in Multichannel News. "There's a lack of proven test cases about how high DOCSIS can scale. So we wanted to simulate what a high-density solution would look like."
Such speeds are currently limited to technology previews, as most real-world deployments are working with a fraction of the channels and therefore achieving much slower speeds. Chapman suggests the prototype modems are at least a year from production, while the company is confident it can build 72-channel modems if necessary.
