During certification wave 25 that just concluded, CableLabs announced that 12 DOCSISÒ 2.0 cable modems had achieved certification status.

The non-profit research and development consortium- Cable Television Laboratories- founded in 1988 by members of the cable television industry pursues new cable telecommunications technologies and helps the members integrate those advancements into their business objectives, says an official release.

During current certification session, eight companies have gained certified status for DOCSIS 1.1 products, one gained DOCSIS 1.1 qualified status for headend equipment. DOCSIS 2.0 modems from Ambit, Arris, Castlenet, Com21, Hitron, LinkSys, Motorola, Scientific-Atlanta, Terayon, and Thomson were also certified, .

The DOCSIS 2.0 modem speeds up to 600 times faster than the standard dial-up telephone modems. Armed with DOCSIS 2.0 modem, the cable operators can carry so-called peer-to-peer and business services that require high-speed two-way capability.

Since it is also backward compatible with earlier versions of DOCSIS products, advanced Internet Protocol (IP)-based cable services can support it. It adds advanced digital modulation capabilities to cable modems and headend equipment enabling cable companies to increase by a factor of three the speed of the return (or upstream) path of their networks as compared to DOCSIS 1.1, or a factor of six as compared to DOCSIS 1.0.
