sb6141If you are looking for cable modem that offers innovative high-bandwidth data and multimedia services, Motorola SB6141 is one of the good choice. The SB6141’s comes with higher-speed services enable you to protect an installed base of high-speed data users, deliver high-bandwidth, multimedia services, deliver competitive plus high-capacity commercial services to your business customers. This Motorola SB6141 Cable Modem utilizing the power of DOCSIS 3.0, it is enables channel bonding of up to eight downstream channels and four upstream channels, which gives you an advanced multimedia services.

DOCSIS stands for Data Over Cable Service Interface Specification. SB6141 modem from motorola  is the third and the latest version of DOCSIS; the 3.0 specification was actually released way back in August 2006 by a consortium of technology companies led Cablelabs of which Motorola is a member to use channel bonding technologies to provide ultra fast broadband services.


SB6141 Cable Modem Overview

Many question, how does this channel bonding technology helps to improve the data transfer speed? In simple terms, a modem like the Motorola SB6141 utilizes the channel bonding technology together with the DOCSIS 3.0 standard to cleverly harness the extra unused bandwidth capacity to provide the boost to users.

Imagine combining eight large pipe of 40 Mbps data per channel to give you a theoretical total downstream capacity of 320 Mbps? In the theoretical or optimal case, you could utilize data rates of more than 320 Mbps downstream and 160 Mbps for upstream channels.

However do note that like all modems, actual data throughput will generally be less due to physical layer overheads such as: error correction coding, burst preamble, guard correction, etc. Plus you never know precisely what you get from you pay for. For example if you subscribe to a 20 Mbps package from your ISP, you will not be able to take the full advantage of the SB6141′s data capacity due to the capping from your ISP.

Using this modem, even though users cannot make total use of its theoretical through put, most users of the Motorola SB6141 would feel the speed surge immediately when they switched over to the SB6141. The SB6141 also backwards-compatible to DOCSIS 1.0, 1.1 & 2.0 and it supports both IPv4 and IPv6, Advanced Encryption Services, and all other DOCSIS 3.0 standards. As part of Motorola DOCSIS 3.0 Ultra-Broadband family of products, the SB6141 tuner has flexibility of two individual capture bandwidth groups, each 96 MHZ. These downstream capture windows can be placed independently anywhere within the 108 MHz to 1 GHz spectrum for deployment of new high-value services, such as bandwidth on-demand, commercial services, interactive gaming, and IPTV.
