Xerox PARC, now called Palo Alto Research Center (PARC), invented the Ethernet computer networking system in 1973 and paved the way for computers and related devices to share files and internet access. Today, Ethernet cables connect hundreds of millions of devices in businesses and homes globally.
Still, it might be confusing when looking for the best internet cable to use for an installation, so we present this guide. It is a brief coverage of the types of Ethernet cables and tips for choosing the best cable to use in your Ethernet networking project.
One may wonder why it is necessary to categorize the Ethernet cables. From the user’s standpoint, specifying the cable is much easier. Manufacturers also benefit from the categorization because it not only provides consistency but also enables them to supplier cables according to applications.
Below is an explanation of various types of internet cables and their categories of Ethernet cables. Cat represents "category".
This type of data cable is the most basic today and first appeared in 1995. It has a peak 100 Mbps data rate. Its maximum distance for distribution of video, data, and telephone signals is 100 meters. It is unshielded and offers a maximum bandwidth of 100MHz. This internet cable type is probably obsolete by now.
The ‘e’ stands for enhanced, meaning that compared to cat 5, this cable has a better data rate. This type of internet cable can support up to 1 Gbps because it has more twists that increase crosstalk resistance.
Even better than cat 5E, cat 6 offers higher data transfer speed and bandwidth. It may be only capable of 1 Gbps at 100m (similar to cat 5E), but its enhanced shielding can improve reducing potential interferences.
As an evolution of the previous Cat6, this new type Cat6A first appeared in 2004, but the standard was published five years later. It doubles the frequency range of Cat 6 to 500 MHz and offers 10Gbps speed. It supports 10GBASE-T at 100 meters to ensure that the fastest Ethernet applications on the market can be supported at the maximum stated length.
With the growing demand for faster data transfer and internet speed, it was not long before cat 7 emerged. The designers wanted to achieve 10 Gbps Ethernet, but tests have shown that it can deliver up to 100 Gbps at shorter distances.
This simple comparison table and the points that follow can get you started.

Our cables are in line with the industry standard for 10 Gigabit Ethernet cabling. To further develop our DataCom product ranges and cement our recommendation of 6A data cables, we are launching two new Cat 6A data cables. These will complete the current range, which now becomes U/UTP with CPR Dca (new ref. 219312), F/UTP with CPR Dca (new ref. 219322), and U/FTP with CPR Cca (ref. 219302).
We have the following classification for our broad range of data cable options:
