What is DOCSIS Cable Modems?
DOCSIS (Data Over Cable Service Interface Specification) is a technology developed by CableLabs for transfer of data over coaxial cable that are deployed and used for cable TV connection. Cable operators across the world have adopted DOCSIS standards in Cable Modems for providing internet data, voice and video services using existing cable TV systems.
DOCSIS 3.1 offers a huge jump in download and upload internet speeds over DOCSIS 3.0, supporting up to 10 Gbps download and 1 Gbps upload speeds. Using DOCSIS 3.1, Comcast is offering Gigabit and Gigabit Pro Internet service with 1 and 2 Gigabit download speeds.
Gigabit internet plans may be costly but the high speeds make it worthwhile for avid streamers and online gamers. One way to mitigate this cost is by ditching your rented networking equipment and providing your own gigabit modem and router.
If your endgame is Gigabit-speed Internet then you will have to upgrade to a DOCSIS 3.1 modem sooner or later. The main benefit of this technology is that its max downstream caps out at 10 Gbps and its upstream caps out at 2 Gbps. Gigabit speeds are offered by the nation’s largest ISPs, including Comcast Xfinity, AT&T, Cox, CenturyLink, and Google Fiber. If you live in a metropolitan area, you are probably in one of these networks.
