CableLabs has begun testing the first set of DOCSIS 3.0 gear, as five companies have submitted cable modems to the organization for official approval. We’ve seen precertification equipment tested, and some cable ISPs in Asia have rolled out pre-DOCSIS 3.0 equipment, but this is the first set of gear to be tested for compliance with the final DOCSIS 3.0 standard.
Cable ISPs currently use DOCSIS 1.1, which has been “good enough” in the past. Unfortunately, when compared to fiber, DOCSIS 1.1 lacks in the speed department. DOCSIS 3.0 has the potential to drastically change that, with download speeds of up to 160Mbps and uploads of up to 120Mbps possible. In addition, DOCSIS 3.0 also offers full support for IPv6, along with enhanced network management and security features. DOCSIS 3.0 also offers enough bandwidth for IPTV and other high-def video services.
