Television provides news, entertainment, and instructional programming into the homes of millions of people. Many people prefer cable television (CATV) to broadcast television because it offers a sharper picture and more channels. The technology that allowed cable users to receive satellite signals over the cable architecture that had grown from its roots as Community Antenna Television was created in the mid-1970s, giving cable television its modern shape. With this new delivery technology, cable firms were able to provide clients with more channels than traditional terrestrial broadcasters. For instance, Spectrum TV offers more than two hundred HD channels to its users and at very reasonable rates.

The introduction of cable television in the 1970s provided a higher number of channels while also resolving antenna reception issues. Cable TV is the most extensively utilized television reception medium, as it uses a direct feed to the television or decoder box. Understanding how cable television works give you an understanding of how a single cable running into your home can convey so much data.

Cable TV

Cable TV, also referred to as CATV, in simplest words is a means of providing subscribers with access to television programs via coaxial or optical fiber cable installed in their homes. In the late 1940s, cable television networks were developed in the United States to increase the reception of commercial network broadcasts in rural and hilly locations. They were first used in the 1960s in several large urban areas where local television reception is hampered by signal reflection from tall buildings. These cable systems, also known as community antenna television, employ a community antenna to collect broadcast signals, which they then retransmit via cables to subscribers’ homes and businesses in the local region. In addition to an initial installation fee, subscribers must pay a monthly service charge.

How Does Cable TV Work?

Satellites are used by television networks to broadcast their programming. Head-ends; the control centers for cable networks are installed by cable operators to aggregate TV channels received from several satellites. They combine this with programming from other sources, such as broadband connections, local channels, and more, to create an array of channels, which they can then broadcast to households via a coaxial cable network, giving it the name cable TV, placed underground or hanging over utility poles. To use cable television, one must first subscribe to a cable company, which will then connect the television sets to the wall socket through a simple coaxial cable. The cable channels are then programmed into your cable-ready television sets. If you don’t have a cable-ready television, you’ll need to purchase and install a converter box.

What is Optical Fiber?

An optical fiber is a flexible, transparent fiber that is slightly thicker than human hair and is constructed of glass, sometimes known as silica or plastic. It transmits light between the two ends of the fiber as a waveguide or light pipe. The fact that fiber-optic cable does not suffer from the same signal losses as coaxial cable means that fewer amplifiers are required.

Greater customization was another advantage of switching to fiber-optic cable. Because a single fiber-optic cable could reach 500 homes, it became practical to send messages and services to specific neighborhoods. Cable providers discovered in the 1990s that this similar neighborhood grouping was suitable for establishing a local-area network and delivering Internet access via cable modems.

What is Coaxial Cable?

An inner conductor is encircled by a flexible, insulating tubular layer, which is wrapped by another tubular conducting shield in a coaxial cable, or coax. The term coaxial refers to the shared geometric axis between the inner conductor and the outer shield. For radio frequency signals, a coaxial cable is utilized as a transmission line. Feed lines connect radio transmitters and receivers to their antennas, computer network (internet) connections, and the distribution of cable television signals are all examples of its uses.

Is Cable TV dependent on Internet?

Most certainly not. While your Internet and cable TV services are connected by the same coax line, they do not use the same technology or signal frequency. Instead, two distinct signals are received, and the two signals are divided apart to drive the two services you receive, whether they are received within your home or outside of it. One of the two signals could be malfunctioning, while the other is functioning perfectly. If the Internet is down, it could be due to a variety of issues, but the majority aren’t related to the cable plant because that would affect both services. When the Internet goes down, it’s usually due to an issue with network administration or engineering, such as the cable company’s backbone link going down or a router to which you’re connected going down.

The only thing you can do in such a case is, try rebooting your modem or the router to see if it fixes the problem. If this is not the case, contact your cable provider and inform them.


Cable TV has a very simple yet very fascinating working system. All our houses are connected to a cable connection, whether for our cable TV connections or the provision of internet services. Either way, they are very crucial in keeping us updated about the world regardless of the distance. Now choosing between coaxial cable or optical fibers is something you will have to decide based upon your location and most importantly your consumption and requirements.
