What Is Cat8 Cable?
If you’ve been in the Datacom and Networking business, you would be familiar with some of the Ethernet cables available such as Cat5E, Cat6, and Cat6A. Well, the latest network copper cable will be known as Cat8 Cable, no surprise there right? This article will cover the basic idea of what Cat8 cable is and the performance you can expect.
Twisted Pair CAT 8 Cable Standards
To keep it simple, the reason why copper cables are twisted as pairs, is because the twisting of two wires would help contain the electromagnetic field that would be created as a result of electrical signals passing through the wires. Frequency characteristics of the twisted wire can limit the actual speed of data passing through a twisted pair. When the cable has a higher frequency characteristic, it means that the wire is able to contain the electromagnetic fields at higher frequency rates allowing higher speeds.
One way to increase frequency characteristics is to have more twists, more twists provides higher frequency characteristics. Another way to increase frequency characteristics is by using individually shielded pairs.
As technology advances the demand for increased data speeds will continue to grow and manufacturers will continue to develop twisted pair cables that can support those higher speeds.
Here are the current Category standards for twisted pair cables:
Cat3 – 1 MHz, 10 Mbps
Cat5 & Cat5e – 100 MHz, 100 Mbps
Cat6 – 250 MHz, 1 Gbps
Cat7 – 600 MHz, 10 Gbps
Cat7A – 1000 MHz, 10 Gbps+
Cat8 – 2000MHz, 40Gbps
Category 8 Standard
As you can see by the Category standards above, you can expect CAT 8 to provide better frequency characteristics, therefore supporting higher speeds of data. Cat8 is capable of supporting bandwidths of up to 2 GHz (2000 MHz) for up to 30 meters of cabling. Cat8 can also support 25Gbps/ 40Gbs speeds up to a maximum channel lenght of 30 meteres. The physical appearance of Cat8 cable is similar to lower category cables and still terminated in RJ45 connections.
