(Telecompaper) Arris has announced its first Docsis 3.1 modems, the Touchstone CM8200 and SurfBoard SB8200. The CM8200 is aimed at operators and delivers data rates of over 5 Gbps downstream and 2 Gbps upstream. It features switchable filters with 1218 MHz downstream and 240 MHz upstream to support reliable gigabit performance while reducing interference in the home network. The SurfBoard SB8200 offers the same features as the first, but is intended for retail customers, who can take advantage of its 32x8 QAM channel bonding capabilities on Docsis 3.0 cable systems. Arris will display the two products at the SCTE Cable-Tec Expo between 14-16 October and will become available next year. Arris will expand the line to include telephony modems and additional voice and data gateways.
