According to the predictions, Ethernet will be phased out by 2025. Google attempted to establish fibre optics as the new standard for household internet connections, and it was a natural choice for scaling industrial applications due to its low cost. Ethernet has managed to hang on for the time being, with new variations emerging every few years that push the boundaries of standard copper cables even farther. Cat8 is the most recent incarnation of the protocol, which we’ll discuss today. We’ll start with the fundamentals, but in only a few minutes, you’ll understand what Cat8 is, how it works, and why you should be concerned about it.
The Differences Among Ethernet Category Types
You’ve probably come across the “cat” or category designations, such as Cat5e, Cat6, and Cat6a. You may be familiar with Cat7 if you operate in a more robust internet environment. The general rule is that a more significant number indicates a newer technology that is capable of supporting larger data rates; however, it is only one of the primary differences:
Standard bandwidth (measured in MHz)
Maximum data transfer rate (measured in megabits per second)
Shielding
The majority of the time, it comes down to twists and shielding. Higher frequencies need additional twists in the cable pairs, which increases the cost of the procedure. Furthermore, as the frequency range increases, it becomes increasingly difficult to protect higher frequencies from interference and crosstalk, and the cost of raw materials for shielding increases as the size of the operation increases. Cat7, for example, frequently employs gold plates as a form of shielding.
Because interference can leave a cable inoperable, this is a significant issue. S/FTP shielding is one of the most common and trustworthy shielding methods for Cat8 networks. This provides the highest level of protection against interference and may be found in the top-performing copper cables on the market.
The Definition of Standard Bandwidth
Because standard bandwidth is such a motivating factor in cable design, let’s look at how frequency works in practice. It boils down to how many ones and zeroes can be transmitted across the cable in one second based on the frequency of the cable. For standard Cat5 connections, that translates to 100 million signals every second (or 100 Mhz). Cat8 transmits signals at a rate of 2 billion (2 GHz), which is unique in the industry. This means that the cable density and shielding quality required to make it function is different from what is now available. When you realize that Cat8 is capable of data transfers 250 to 400 times quicker than Cat5, it becomes clear why.

With the exponential increase in the volume of data being stored, the rapid centralization of data to the cloud, and the ever-increasing bandwidth available through broadband and 5G network hardware manufacturers, IT managers and data centre engineers are constantly looking for quick, easy, and less expensive ways to move more data. CAT8 cable is the new “go-to” cabling solution outside fibre optics. Essentially, any enterprise that requires the scaling of fibre optics may be seeking to replace Cat6 with Cat8 over the next few years.
