This knowledge is irrelevant to most home users. Length: 16 feet. Category 8, Cat8 cable or Cat-8 cable is an ethernet cable which is a different type of cable standing apart from the previous cables. Cat8 uses an unprecedented 2 billion (2 GHz) signals per second. FTP or SFTP (Foiled Twisted Pairs): Foil shielding protects these cables, which helps to reduce noise and improve connection quality. You’ll still find Cat 5 cables in use, but you should avoid them altogether. Cat8 cable is also backward compatible with its previous versions. Cat 7 cables support higher bandwidths and significantly faster transmission speeds than Cat 6 cables by utilizing the newest widely available Ethernet technology. You certainly can use Cat8 in a home network but it's really designed for high-speed switch to switch communication in a data center. If your subscription only supports 50Mbps downloads, purchasing a 1Gbps Ethernet cable is simply overkill — at least for now. What Is Cat6 Cable? Cat-8: Cat 8 cables have now been released and provide a huge step up in data rate / bandwidth. Digital Trends may earn a commission when you buy through links on our site. Below, you can see the capabilities of each cable type (we’re skipping categories 1, 2, and 4, as they are not technically recognized as Ethernet standards and have no application today). UTP (Unshielded Twisted Pairs): These cables won’t have foil or braided shielding. The launch of a Cat 8.2 copper cable system is set to transform data centre infrastructures by providing a cost effective alternative to fibre optic solutions for both 25GBase-T and 40GBase-T installations as Lee Stokes, UC Connect Product Manager at Draka. As today’s routers become faster and more capable, facilitating faster network speeds, you need more capable cables to take full advantage. Cat 8 is an emerging technology, although cables are currently available for purchase. Vandesail Ethernet Cable — Cat 7. Cat 8 Cable: The new 2GHz speed limit Finally, Category 8 is the new spec on the cable block. The “a” in Cat 6a stands for “augmented.” Cables based on this standard are a step up from Cat 6 versions by supporting twice the maximum bandwidth. The physical appearance of Cat8 cable is similar to lower category cables and it can be terminated in RJ45 connections or non-RJ45 connections. Plus, the heavier gauge Cat8 cable is quite rigid, making it more difficult to install and terminate. … HDBaseT is transmitted over 6A up to 100 m (328 ft) long, with 8P8C modular connectors of the type commonly used for ethernet local area network connections. It represents a significant leap in data transfer speed over the earlier Cat7 and Cat6a cables. The right infrastructure cabling will facilitate maximum speed and performance. Further descriptions of Cat-5 and Cat-5e cables are given below as these are widely used for Ethernet networking applications today. “Cat” simply stands for “Category.” The number that follows indicates the specification version supported by the cable. Cat 6a cables come shielded, and their sheathing — which is thick enough to eliminate crosstalk — makes for a much denser, less flexible cable than Cat 6. A common misunderstanding is that Cat5e patch cables are not capable of running at Gigabit speeds, and Cat6 or above is required. Therefore, even if your internet plan doesn’t offer speeds up to 100 Mbps, a Cat 5 cable will likely not be your best option simply because they are hard to find new. To help out, we put together a quick rundown on what the different terms mean, and what you should expect when buying cables with those designations. Shielded foiled twisted pair (S/FTP) construction includes shielding around each pair of wires within the cable to reduce near-end crosstalk (NEXT) and braiding around the group of pairs to minimize EMI/RFI line noise in crowded network installations. That modified GG45 connector is a proprietary component though, and while the backward compatibility helped a little, there are still issues with following previous Ethernet standards. That means they’re more flexible and cheaper to produce, but you’ll sacrifice signal quality and increase vulnerability for crosstalk. Table 1: Ethernet Cable Speeds and Bandwidth. Nippon Labs Cat8 Ethernet Cable 5 feet, White - 2GHz, 40G, 24AWG, S/FTP - Shielded Latest 40Gbps 2000Mhz SFTP Patch Cord, Heavy Duty High Speed Cat 8 LAN Network RJ45 Cable That high frequency requires shielding, meaning you’ll never find unshielded Cat 8 cables. We’ve defined these terms and put together tables comparing the benefits and issues with each. Cat 8 is also the only cable to meet the latest IEEE standards (the aforementioned 40Gbps and 2,000MHz frequency), which is one reason it’s a great choice for future-proofing, despite the significantly higher costs. All models support PoE and offer convenient snagless RJ45 connectors, integral strain relief and a lifetime warranty. 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. These Ethernet cables are used to trans… This improvement may be useful in some instances, but Cat 7a cables are far more expensive than any other option. Most importantly, Cat8 Ethernet patch cables can support a speed of 25 Gbps or even 40 Gbps. TP (Twisted Pairs): Refers to how the wires inside twist together. When shopping for cables, you may notice they’re nearly always classified as “Cat-5,” “Cat6e,” or something similar. It requires shielded cabling as well. Cat8 Ethernet Cable Offers Faster Speeds and Better Performance. If that’s not the case and you only surf the internet’s shallow waters, you don’t need a fast in-homer network. This is why Ethernet cables tend to have two-speed ratings, one at 10-30 meters and one at 100 meters: Since the 100-meter rating doesn’t matter outside of very large professional projects, we suggest just focusing on the 10-30 meter numbers. The Need for Speed . CAT 5/5e – 100 MHz, 100 Mbps. The first Ethernet Cable with a Cat 8 designation finds its … That difficulty led to the development of Cat 6a, and a lot of marketing confusion, since some sellers started referring to Cat 6a as the new Cat 7.
