Is DOCSIS 3.1 the Next Big Thing in Global Cable TV?

Read MoreHide Full Article

The need to remain connected is essentially human. An era of digitization and technology is built on this need. It is here that telecommunications come to the fore as a necessary utility. The rising demand for technologically superior products has been a silver lining for the telecom space in an otherwise tough environment. With the global telecom industry continuously evolving, companies in the league are fighting it out to stay ahead in the competition. The latest in the league is the newly launched DOCSIS 3.1 technology.

DOCSIS 3.1 versus DOCSIS 3.0 

DOCSIS (Data Over Cable Service Interface Specification) is a communications protocol that allows cable MSOs to provide high-speed broadband connections. This technology was specifically designed as the cable TV industry’s answer to high-speed wireless and fiber-based wireline networks of telecom operators. The old-generation DOCSIS 3.0 technology has helped cable TV operators compete in the race for the fastest internet speed available in the market.

The next-generation DOCSIS 3.1 standard is an improved formulation of the existing DOCSIS 3.0. Theoretically, while DOCSIS 3.0 supports 152 Mbps download and 108 Mbps upload speeds, DOCSIS 3.1 offers as high as 10 Gbps downstream and up to 1 Gbps upstream network capabilities. Additionally, DOCSIS 3.1 comes with several operational benefits.

The technology is also backward compatible, allowing the present hybrid fiber-coaxial cable lines to allow such high internet speed by simply switching to a DOCSIS 3.1 compatible modem. Although FTTH has the advantage of providing unlimited bandwidth, backward compatibility is a major advantage of DOCSIS 3.1. This allows cable MSOs to provide high-speed Gigabit broadband to customers, without having to incur additional digging or other cable laying costs, unlike FTTH providers. This is sure to boost margins of cable MSOs.

Major Players

In the U.S., the largest cable MSO (multi service operator) Comcast Corp. (CMCSA - Free Report) is extensively deploying DOCSIS 3.1 network in several markets. The company is offering 1 Gbps downstream and 35 Mbps upstream speeds for its DOCSIS 3.1 network. Mediacom Communications is also offering DOCSIS 3.1. Cox Communications is currently going through the trial phase of this technology.  

Leading European cable MSO Liberty Global plc. (LBTYA - Free Report) has decided to install DOCSIS 3.1 infrastructure from the fourth quarter of 2017. Major DOCSIS 3.1 equipment manufacturers are ARRIS International plc. , NETGEAR Inc. (NTGR - Free Report) and Casa Systems Inc. All the above mentioned stocks currently carry a Zacks Rank #3 (Hold).
