What Is CAT8 Cable and When Will It Be Available?

Posted by Quan Thach on

If you’ve been in the Datacom and Networking business, you would be familiar with some of the Ethernet cables available such as CAT 5E, CAT 6, and CAT 7. Well, the latest network copper cable will be known as CAT 8 Cable, no surprise there right? This article will cover the basic idea of what CAT 8 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:

CAT 3 – 1 MHz, 10 Mbps

CAT 5/5e – 100 MHz, 100 Mbps

CAT 6 – 250 MHz, 1 Gbps

CAT 7 – 600 MHz, 10 Gbps

CAT 7a – 1000 MHz, 10 Gbps+

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. CAT 8 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. The physical appearance of CAT 8 cable is similar to lower category cables and still terminated in RJ45 connections.

Where can you buy CAT 8?

There are several marketplaces to find CAT8 patch cords for sale such as Amazon, Ebay, and a quick Google search. A few distributors are offering CAT 8 cable in bulk 500ft. reels with price ranging between $975 - $989 average.

We, here at Infinity Cable Products, will be offering CAT 8 cable also in 4th quarter of 2018. Our CAT 8 cable is currently undergoing extensive testing and obtaining all the certifications necessary to deem true CAT 8 cable quality. We are excited to offer the best CAT 8 the market has to offer, be sure to check back with us soon!

Feel free to shoot us a message if you'd like to be added to our mailing list to be updated once CAT 8 arrives (support@infinity-cable.com). Thank you!
