How the Cable TV is Used for Internet Access?


Some users may have a tough time coming to terms with the fact that cable TV can also be used to establish a connection to the internet. Other people may feel uneasy at the fact that cable TV, an entity that is under threat from the likes of streaming services such as Netflix and Amazon Prime, would help boost the consumption of that very product!

This article would especially come in handy for those individuals or households that have a greater inclination towards saving money instead of spending freely. These individuals or households give economists a tough time when they try to develop policies that could boost economic indicators, like economic growth, etc. However, in stringent times like these, where the coronavirus pandemic has left many people feeling uneasy and stressed, saving money for a rainy day doesn’t exactly seem like the worst option out there for thrifty consumers.

There are numerous service providers in the market, who can provide the internet through their cable connections. Most of these companies have a somewhat limited scale of availability when it comes to providing services. Hence, it would be wise to first look up the availability of cable services before setting your sight on a cable TV service provider.

Companies like Cox cable offer their customers the latest network technology, i.e. hybrid fiber-coaxial cable. Through this hybrid tech, a consumer or client may end up getting the benefit that comes with both types of cable connections. Fiber optic tech provides a higher speed and a better connection with minimal loss in data or quality and coaxial cable provides the customer with the strength in the connection that is needed for longevity.

How the Cable TV Utilizes a Hybrid of Fiber Optic and Coaxial Cable Material to Provide Internet Connectivity?

Many people don’t know that they can just as easily utilize cable TV to get or establish a connection with a desktop computer, a laptop, or even a local network. This type of connection to the internet is somewhat of a direct competitor or substitute to the Digital Subscriber Line (DSL) technology.

The hybrid connection of fiber optic and coaxial cable helps in delivering internet connectivity through cable TV. The cable connection, which is laid down between the cable TV company and its distribution points or optical nodes – the technical term that is often used to describe them, is established via fiber optic technology so that there is minimal loss in data. These connections cover distances that go as far as 25 miles i.e. 40 kilometers. However, the connection that exists between the optical nodes is made through a coaxial cable material. The main purpose of using this type of material at this junction is to give signal amplifiers enough space to improve or rejuvenate the signal, hence taking it to the highest level. On average, a single entity or optical node tends to provide services to as many as 500 to 2,000 clients, depending on their locations. Due to this very fact, cable TV companies can provide a seamless cable TV experience. It would not be a far stretch to assume that similar technology can be used to provide a good and stable internet connection.

Specifications of Cable TV and Internet Access

One of the most common levels of infrastructure that is utilized by cable TV companies, which offer internet connections, is known as the Data Over Cable Service Interface Specification tech. It’s a mouthful, we know. Hence, we suggest that you just stick to calling it DOCSIS.

As of right now, there are only 4 versions of DOCSIS that are available for use in the market and they are Versions 1.0, 1.1, 2.0, and lastly, the 3.0 version.

The versions 1.0 and 1.1 are identical in many specifications and features but have a slight difference. The 1.1 version is adjusted to incorporate QoS parameters, which are also known as the Quality of Service parameters. Due to the QoS parameters, cable TV connections can be used to establish a telephonic link in the area of connection.

To Conclude

The coaxial cable connection has numerous advantages to its name. One of the most important features of this technology is that it makes broadband communication possible. This is achieved through the effective utilization of different frequencies so that numerous channels can be transmitted at a time.

However, the speed of the internet that you can get is quite subjective. The reason for this is that there is a set limit on the optical node. This means that the connection would be shared among all the users that have a working connection. Hence, the greater the number of users, the lesser the amount of bandwidth that will be available for a single user.
