Ethernet network cables are one of the main pieces to be able to have the internet. It does not matter if it is at home, at university or at work, the network cable is essential for a network system to work optimally. However, there are several types of Ethernet cables and these will vary depending on the speed of the internet you want to have. That is why today we explain everything about the ethernet network cables and how to choose the right one.
As well known as RJ45 cables, Ethernet cables can give you a higher internet speed depending on the one you choose, as well as its proper use. Just imagine that you hire a fiber optic internet service that allows you to surf at high speeds, but you connect to the internet through the Wi-Fi at home. You would not be taking advantage of the internet speed because the best thing would be to connect the network cable directly to your PC.
What is an Ethernet network cable and what is it for?
As its name says, the Ethernet network cable is a cable that allows to establish a connection between the modem and the router or between the modem and the PC directly. This tool is essential, since without it you would not have access to the internet. And although there are devices such as modem-routers that do not need an Ethernet cable to work, the reality is that if you want to connect your PC or laptop directly to the Internet you will need one of these.
If you are one of those who wants to access your PC from anywhere, we recommend you take a look at how to create an FTP server and thus share files from your computer, as it will surely help you.
Another use that you can give this cable is for provide internet in places where the signal from the main router does not reach. Imagine that you have an Ethernet outlet in a room or in a room in your house. Well, from there you can also connect other devices such as signal repeaters, routers, video game consoles or even smart TVs.
What are the categories of an Ethernet network cable?
As we anticipated you, the Ethernet network cables vary depending on the internet speed you want. It would not be logical to think of hiring a 1000 Mbps internet service, but you use a cable that supports an internet speed of up to 100 Mbps.
Category | Speed | Frequency | Download speed |
---|---|---|---|
ETHERNET CAT 5 | 100Mbps | 100MHz | 15.5MB/s |
ETHERNET CAT 5E | 1000Mbps | 100MHz | 150.5MB/s |
ETHERNET CAT 6 | 1000Mbps | 250MHz | 150.5MB/s |
ETHERNET CAT 6A | 10000Mbps | 500MHz | 1.25GB/s |
ETHERNET CAT 7 | 10000Mbps | 600MHz | 1.25GB/s |
ETHERNET CAT 7A | 10000Mbps | 1000MHz | 1.25GB/s |
ETHERNET CAT 8 | 40000Mbps | 2000MHz | 5GB/s |
The table shows three important points to take into account: speed, frequency and download speed. The first tells you the maximum speed supported by cable. The second determines the power of the network, establishes its bandwidth and the rate of data loss along the cable. And the last one, as its name suggests, shows you the maximum download speed supported by the cable.
How to differentiate the categories of Ethernet cables?
At first glance there is only one thing that can tell you the type of Ethernet cable you are buying. So don’t worry about the color of the cable, since that tells you absolutely nothing. All Ethernet network cables their category is printed on the cable cover. You can see an example of this in the photo, where you can see that it is a CAT.5 cable (ETHERNET CAT 5).
Another type of difference is the internal one, the one that at first glance you will not be able to know what it is. The important thing here is the material that covers it and protects it from external agents. If you are about to do an internet installation that goes beyond connecting a modem and router to your home, you should pay attention to the following:
- UTP (Unshielded Twisted Pair – unshielded twisted pair): ideal for your home, they have basic protection.
- FTP (Foiled Twisted Pair – Twisted pair with global screen): similar to UTP, but has an extra coating for greater projection.
- STP (Shielded Twisted Pair – shielded twisted pair): designed to go inside the walls.
- SFTP (Shield Foiled Twisted Pair – Shielded and shielded twisted pair): they are covered by a double protection that prevents electrical interference. It is the best option if you need to cover long cable distances.
Which Ethernet Cable Should I Buy?
Now that you know what an Ethernet cable is and how to distinguish between them, the million dollar question arrives, which cable should I buy? From now on we tell you yes you are looking for an Ethernet cable to use within your home networkyou should opt for a Category 5e or 6. Since they cover the maximum speed that -for now- the operators offer you as a service.
But if what you’re looking for is a internal installation of internet throughout your house. You should pay attention to the braiding and coating of the cable, since you should opt for one that protects you from noise and external agents that can damage the cable. We recommend an STP type, since it is mainly designed for this.
