 What is coaxial cable and how does it work?

Generally speaking, coaxial cable is a form of cable that contains an inner conductor that is enclosed by an insulating layer and shielded by an electrically conductive shielding.

Many of them are also equipped with an insulated outer jacket.

The construction of a common cable is depicted in the diagram to the right.

The center conductor is the conduit via which the electrical signal travels.

1. Copper-clad steel is used as the center conductor.

Center conductor bond – a clean stripping polymer is used to prevent moisture migration through the center conductor bond.

2. Dielectric – polyethylene is used to create mechanically stable, closed-cell foam with a high viscosity percentage.

The dielectric core is firmly connected to the first exterior conductor, which is shielded with an aluminum-polymeraluminum film.

The inclusion of a second outside conductor, such as an extra aluminum-polymer-aluminum tape, in tri- and quad-shield designs is intended to improve HF shield isolation before and after flexure while maintaining structural integrity.

3. In tri-shield and quad-shield designs, a third outside conductor – an extra aluminum-polymer-aluminum tape – is utilized to further improve HF shield isolation before and after bending.

When using quad-shield designs, an extra 34 or 36 AWG aluminum braid is utilized as a fourth outer conductor to further increase LF shield isolation in high-RF noise situations.

4. Protectant that is resistant to corrosion

Nondrip material for indoor and aerial applications that are meant to prevent moisture migration into the cable structure.

Small jacket ruptures can be sealed using a flowing chemical underground.

5. Jacket – A UV stable outer jacket made of either polyethylene (PE) or flame retardant polyvinyl chloride (PVC) is provided to protect the core of the cable during installation and for the duration of the cable’s operational life.

Separable web connects an integral messenger, which is a galvanized, carbon steel wire support component, to the cable’s conductor.

Choosing Between the Coaxial Cable and Fiber Optic Cable Might be Difficult

Using either of these types of cables to transmit video, audio, or other sorts of data is possible, and each has its own set of pros and cons when it comes to building up your network infrastructure.

The distance between you and your connection, as well as the quantity of data you want to transfer, will help you choose which option is ideal for you.

Fiber optic lines may transmit a signal for several kilometers before requiring the use of a repeater. Because coax cable has larger signal losses than other types of cable, it should only be used for short distances.

Fiber-optic connections are capable of transmitting far more information.

Fiber optic cable is also much more costly than traditional copper cable.

When compared to coaxial cables, fiber optic cables are seen less commonly in-home and consumer environments.

Coax cables are lightweight, easy to install, and extremely robust.

Fiber is best suited for professional networks, such as those found on a business campus or in a university setting, in part because it has a higher and faster data transmission rate than coax.

The use of a coax cable is recommended if you are working on an installation at home or a data transfer network with a moderate amount of capacity.

A large number of businesses nowadays rely on cable connections for their corporate broadband service.

The most significant disadvantage of cable internet is the volatility in speed.

When comparing fiber internet to cable internet, it is important to remember that cable internet service is typically shared among a number of users.

This implies that if there are a high number of users in a cable region who are all running bandwidth-intensive apps on the internet at the same time, everyone’s internet speeds can fluctuate between 100 percent and 25 percent of the advertised speed, depending on the circumstances.

When it comes to the cost of fiber vs coax, fiber is generally significantly more expensive upfront.

Price differences between dedicated internet access through fiber and shared cable internet connections will become apparent with the construction of fiber optic infrastructure.

Coax Cable for Internet Connection

Coax has long been a service that many companies rely on for internet access because it provides the same dependability and speed that makes it an efficient transmission medium for voice and television signals.

Coaxial cable internet is a typical type of cable connection that many service providers employ.

The way coax internet works is that a data signal is sent from your computer to the modem at your location through your coax connection.

The Ethernet connection between your modem and your computer is responsible for transmitting the data, which allows you to have high-speed internet access.

What’s the difference between coax and fiber internet?

Numerous companies are torn between selecting between fiber and coax internet as the most appropriate option for them. With the infographic below, we’ve made it a little easier for you:

The Advantages of Coaxial Cable Internet


When compared to more traditional network options such as T1s, coax provides better bandwidth speeds at a more affordable price.


Coax is a network that is substantially saturated and may be found in many multi-tenant buildings.

Installation can be rapid and smooth depending on the availability of the equipment in your unique area.


One distinguishing aspect of coax is that its speeds are asymmetric, which means that uploading rates are significantly quicker than downloading speeds.
