Cat-8 Ethernet: A Guide to the Latest and Trending Network Cable

Fast data and signal transmission is a crucial factor of Ethernet cables. From Cat-3, Ethernet has moved forward; now their latest upgrade is making a noise in the IT world, and that is Cat-8 Ethernet cable. 

Cat-8 Ethernet

IT networks relied for so long on cloud and edge data transfer. Though cloud technology was efficient, it was not quick. Delays and interferences are inevitable, especially when there is poor internet connectivity. These issues resulted in poor work performance and productivity in many sectors. The IT sector introduced a new trend that is Ethernet cables to resolve poor data transfer of cloud technology.

Ethernet cables have undergone swift development over the years. From the old Cat-3 to Cat-7a, the drastic development of data and signal transmission significantly improved. The sector introduced another game-changer upgrade, which is the Category 8 (Cat-8) network cable.

What is a Category 8 (Cat-8) Ethernet Cable? 

If you are new to Ethernet cables, chances are you already noticed that every cable version constitutes a number and letter. When you check this guide to network cables, you will learn that these numbers and letters signify the cable version. It also represents the speed of data and signal transmissions and overall performance.

A good rule of thumb is to choose Ethernet cables with a higher number. A higher number indicates s that the cable is faster and displays better performance compared to cables with a lower number.

Cat-8 is the latest classification of network cable. It is an IEEE standard copper Ethernet cable that features a significant leap in transmission speed from the former Cat-6 and Cat-7a versions.

The new Ethernet cable utilizes a standard RJ45 connector. Thus, it is compatible with Ethernet cable port from a different category.

How it Cat-8Different from Older Ethernet Cables? 

The higher data transfer rate of Cat-8 and its impressive overall performance is one of the apparent differences between the cables from older ethernet versions. Cat-6 and Cat7 have a maximum transmission rate of 10Gbps. Meanwhile, the Cat-8 features a maximum data transfer speed of 40 Gbps. Although it is faster, the Cat-8 has a shorter cable length. Its maximum cable length is 30m, whereas Cat-5 to Cat7 has a maximum cable length of 100 meters.

Another key difference of the Cat-8 cable is its shielding. It pertains to the shielded twisted pair (STP) cable, which is a part of the cable jacket. The STP has a layer of conductive material that protects the internal conductors from electromagnetic interference (EMI). Therefore, Ethernet cables with shielding have minimal interferences, faster data transfer rate, and fewer errors.

Cat-6 to Cat-7 cables feature shielding, but only one part of the cable jacket is shielded. In Cat-8, each twisted pair has shielding. In a nutshell, the latter is more capable of eliminating crosstalk and supports a higher transfer rate.

Who can Benefit from Cat-8 Ethernet Cables? 

Cat-8 is the best option for sectors that requires quick data transfer and signal transmission to operate. These sectors encompass communications and data centers, as well as, server rooms. It is also suitable for business use. Gamers can also benefit from category 8 for a better gaming experience.
