For the setup, the cable company has lines of fiber optics run through the ground that are then divided out to sub stations. From these sub stations they connect a main hub outside each home or apartment building. From there the cable is fed from the main hub outside the home in through the wall into the home. The coaxial cable is... more »

In telecommunications, cable Internet access (often called simply cable Internet) is a form of broadband Internet access that uses the cable television (CATV) infrastructure. Like digital subscriber lines and Fiber to the premises, cable Internet access provides network edge connectivity (Last mile access) from the Internet service provider to an end user. It is integrated into the cable television infrastructure analogously to DSL which uses the existing telephone network. CATV networks and telecommunications networks are the two predominant forms of residential Internet access. Recently, both have seen increased competition from fiber deployments, wireless, and mobile networks.
Hardware and bit rates
Broadband cable Internet access requires a cable modem at the customers premises and a cable modem termination system at a cable operator facility, typically a cable television headend. The two are connected via coaxial cable or a Hybrid Fiber Coaxial (HFC) plant. While access networks are sometimes referred to as last-mile technologies, cable Internet systems can typically operate where the distance between the modem and the termination system is up to . If the HFC network is large, the cable modem termination system can be grouped into hubs for efficient management.
Downstream, the direction toward the user, bit rates can be as much 400 megabits per second for business connections, and 100Mbit/s for residential service in some countries. Upstream traffic, originating at the user, ranges from 384Kbit/s to more than 20Mbit/s. One downstream channel can handle hundreds of cable modems. As the system grows, the cable modem termination system can be upgraded with more downstream and upstream ports.
Most Data Over Cable Service Interface Specification (DOCSIS) cable modems restrict upload and download rates, with customizable limits. These limits are set in configuration files which are downloaded to the modem using the Trivial File Transfer Pro read more at » http://en.wikipedia.org/wiki/Cable+Internet+access
