What the Heck Is Can I Use Any Coaxial Cable For The Internet?

When setting up your home internet, you may be wondering if you can use any old coaxial cable. After all, it’s what your cable TV uses. Can I use any coaxial cable for internet?

No, you can’t use any coaxial cable for the internet. It depends on what type of connection you have. If you have a cable modem, you need to use a coaxial cable approved by your service provider. If you have a DSL connection, you can use any coaxial cable.

In this post, I’ll look at those considerations and how to choose the best coaxial cable for your needs.

Coaxial Cable

What Is A Coaxial Cable?

Coaxial cable, or coax, is an electrical cable with an inner conductor surrounded by an insulating layer and an outer conductor.

Coaxial cable is used in various applications, including the internet, computer networking, television and radio broadcasting, and more.

The coaxial cable typically consists of four main parts: the center conductor, the dielectric insulator, the outer conductor, and the jacket. 

The center conductor is typically made of copper or brass and is surrounded by the dielectric insulator, which is made of a material such as plastic or foam.

The outer conductor is typically made of copper or aluminum and is surrounded by the jacket, which is made of a material such as PVC.

 

How Does Coaxial Cable Work For Internet?

A coaxial cable is an electrical cable with an inner conductor surrounded by an insulating layer, an outer conductor, and an additional insulating layer.

The inner conductor is typically made of copper, and the outer conductor is typically made of aluminum.

The additional insulating layer helps to keep the inner conductor from coming into contact with the outer conductor and also helps to protect the inner conductor from electromagnetic interference.

Coaxial cable can be used to carry a variety of signals, including radiofrequency signals, Ethernet signals, and digital video signals.

Coaxial cable is often referred to as RF cable when carrying radiofrequency signals. When used for carrying Ethernet signals, coaxial cable is often referred to as CAT-5 cable.

And when used for carrying digital video signals, coaxial cable is often referred to as HDMI cable.

 

Can I Use Any Coaxial Cable For The Internet?

No, you cannot use just any coaxial cable for the internet. Different types of coaxial cables are designed for different purposes. Using the wrong coaxial cable for your internet connection can result in slower speeds, data loss, and other problems. 

Using the correct coaxial cable is essential to get the best performance from your internet connection. There are two main types of coaxial cables: RG-6 and RG-59.

RG-6

RG-6 is the newer and better standard for internet connections. It has a thicker copper core and is double shielded, which helps to reduce signal interference.

 

RG-59

RG-59 is the older standard and is not as good for internet connections. It has a thinner copper core and is only single shielded, making it more susceptible to signal interference.

To set up a new internet connection, you should use an RG-6 coaxial cable. If you are using an existing coaxial cable for your internet connection, you should check to see if it is RG-6 or RG-59.

If it is RG-59, you may consider upgrading to RG-6 to get the best performance from your internet connection. 

 

Data Speeds With Coaxial Cables

How Fast Are The Data Speeds With Coaxial Cables?

Coaxial cables can carry signals at up to 10 gigabits per second (Gbps). This speed is possible due to the large bandwidth that coaxial cables offer.

Bandwidth is the measure of how much data can be transmitted over a given period, and it is typically expressed in bits per second (bps). 

Coaxial cables have a bandwidth of up to 400 MHz, meaning they can carry up to 400 million bits of data per second.

This makes them ideal for applications that require high data transfer rates, such as video streaming and online gaming.

While the maximum data speed that can be achieved with coaxial cables is 10 Gbps, the actual speed will depend on several factors, such as the quality of the cable, the type of connector used, and the distance between the two devices.

 

Internet Speeds Of Different Fiber Cables

Different types of fiber optic cable can support different speeds. Here is a table of the different types of fiber optic cable and their corresponding maximum data rates:

Type of Fiber Optic Cable Maximum Data Rate:

Cable Type Max Speed
Single-mode fiber 10 GBPS
Multimode fiber 100 GBPS
Plastic optical fiber 1 GBPS
Glass optical fiber 10 GBPS

SuddenLink 1 GBPS
Mediacom 1 GBPS
Frontier 1 GBPS
Coaxial 1 GBPS
CenturyLink 1 GBPS
AT&T 1 GBPS

 

Different Between Fiber-Optic And Coaxial Cables

There are several key differences between fiber-optic and coaxial cables. Fiber-optic cables are much thinner and lighter than coaxial cables. 

Additionally, fiber-optic cables can carry much more data than coaxial cables. Here are some of the differences between them:

  • Coaxial cables are made of copper, while fiber-optic cables are made of glass or plastic.
  • Coaxial cables are thicker and can carry more data than fiber-optic cables.
  • Fiber-optic cables are less susceptible to interference than coaxial cables.
  • Coaxial cables are less expensive than fiber-optic cables.
  • Fiber-optic cables can transmit data over longer distances than coaxial cables.

Coaxial Vs. Ethernet: Which Can Give You Smooth Internet?

There is a considerable debate on which internet connection type is better: coaxial or Ethernet. Both have pros and cons, so it depends on your specific needs. 

Here is a breakdown of each type of connection to help you decide which is best for you.

Coaxial

  • Coaxial cables are the traditional type of internet connection.
  • They are typically cheaper than Ethernet cables.
  • Coaxial cables are more resistant to interference than Ethernet cables.
  • However, coaxial cables are more challenging to install than Ethernet cables.

Ethernet

  • Ethernet cables are the newer type of internet connection.
  • They are typically faster than coaxial cables.
  • Ethernet cables are easier to install than coaxial cables.
  • However, Ethernet cables are more susceptible to interference than coaxial cables.

So, which type of connection is best for you? 

Coaxial is the way to go if you are looking for a cheaper option more resistant to interference. However, if you are looking for a faster connection that is easier to install, then Ethernet is the better option.

Convert Coax to Ethernet

How Do I Convert Coax to Ethernet?

There are a few different ways that you can convert Coax to Ethernet, depending on your needs.

Ethernet Adapter

You can use a coax to Ethernet adapter if you need to connect one device to your network. These devices are relatively inexpensive and easy to find. 

Ethernet Bridge

When connecting multiple devices, you can use coax to Ethernet bridge. These devices are more expensive, but they allow you to connect multiple devices to your network.

Frequently Asked Questions

Are All Coax Internet Cables The Same?

Cables that have an impedance of 75 Ohm () and 50 Ohm () are the two most common varieties. Video transmissions typically need 75 Ohm connections, but data and wireless communications often require 50 Ohm cables.

Is The Internet Available Via All Coaxial Outlets?

You’ll need an active outlet to get an internet or TV signal from Midco. Your Midco modem or cable TV equipment may not operate properly because not all your home’s outlets are active. 

If this is the case, you’ll need to either locate another outlet or activate the one you’re using.

Which Coax Cable Should I Use For Internet?

Either red (no signal) or green (signal) will be shown on the LED light indication (signal). The internet cannot be accessed via the coax outlets or wires with red light; however, the ones with a green light are usable.

Is Internet Speed Affected By Coax Cable?

Coaxial cable does not slow down your Internet connection, so that’s the quick answer. Using it, your internet may be considerably improved. With HT-EM4 MoCA adapters, you can improve Wi-Fi coverage across your house.

RG6 Or RG59, Which One Is Better?

It is possible to transmit signals over a greater distance with RG6 cables, which maintain a higher level of quality than RG59 cables. 

High-frequency applications such as TV connections, on the other hand, often need RG6 cables, whereas low-frequency and short-distance transmission require RG59 cables.

Can I Use Ethernet Instead Of Coax?

Ethernet over Coax is an alternate option (EoC). MoCA or Multimedia over Coax uses coaxial cables in the house to transmit Ethernet signals. There is coax in your walls if you have Cable TV service.
