Shielded cabling systems are strongly recommended for category 6A (Class EA) installations, but the user still has to choose between two optional shielding options: F/UTP or U/FTP. This presentations shows the inherent benefits of U/FTP cables of F/UTP cables. The comparison is done for cables containing only a single drain wire. Cables with an overall […]
UTP cable (Unshielded Twisted Pair) Twisted pair cable is the most used, it does not possess any additional protection to the PVC coated and it has 100 Ohm impedance. The connector most commonly used in this type of cable is the RJ45, similar to the RJ11 used in phones (but a little large), but they […]
Im Zusammenhang mit einer Netzwerkverkabelung (Kupfer) müssen unterschiedliche Normen berücksichtigt werden. Die internationale ISO/IEC 11801 und die europäische EN 50173 Norm sind nahezu gleich und unterscheiden, im Gegensatz zur amerikanischen Norm TIA/EIA 568, zwischen Kategorie und Klassen. Die Kategorie (Cat 5, Cat 6, Cat 6A, Cat 7 etc.) beschreibt, nach welchen Methoden und Werten die […]
Q: What is Category 8 Cabling and who devloped the standard? A: Category 8 cabling is the latest category of cabling that has been developed to support 25GBASE-T and 40GBASE-T applications developed by the IEEE. The Category 8 standard was developed by the ANSI/TIA-568 standards body, more specifically, the TR42.7 committee. The document that details […]
“Class” means something completely different than “category”. The class (or category link in American English) always applies to the installed link, the category as such applies only to one single component, e.g. the cable or the outlet; the component is tested and verified by either the labs of the manufacturer or independent verification labs. […]
Believe it or not, there is no straightforward answer to this question. Most countries in Europe have been using STP cabling for a long time, whereas in the US and in Canada, UTP has maintained dominance with over 95 percent of the installed base using UTP instead of STP. A best practice is to stay […]
The Telecommunications Industry Association’s TR-42 Engineering Committee and its subcommittees met the week of January 25, and one of the more significant results of the meeting was that the Category 8 standard—long in development within the TR-42.7 subcommittee focused on copper cabling systems—is just one step away from approval and publication. The standard is in […]
