100% Component Testing
Beyond mated performance and mechanical testing, an additional measure to ensure patch cord performance is to test each patch cord to the TIA/EIA-568-B.2 component requirement. ZION COMMUNICATION implements a strict ISO 9001 quality procedure that 100% tests every patch cord to the electrical transmission requirements per TIA/EIA-568-B.2. Every patch cord assembly produced is tested for Wire Map, NEXT, and Return Loss using a Fluke Digital Cable Analyzer. Each patch cord is then shipped with a quality control label, which is referencedto actual test data verifying high performance.
Know Your Cat.s Cable Categories
The classification of patch cables into categories 1 to 7 follows the general definition of classes A to G for connections and transmission channels in the ISO/IEC 11801 specification. The category therefore always designates a single component of a transmission channel. In the case described here the cables, but can also be, for example, the junction boxes or plugs and sockets, while the class designates the entire channel. Above class F, class G is still defined with subclasses I and II, and, analogously, cabling categories 8, 8.1, and 8.2 are defined. For modern cabling, these are relevant from class D or Cat.5e
Standard for Prosumer
Cables of this category are used for class D transmission channels and are most commonly found in existing installations. They can transmit frequencies up to 100MHz and are divided into Cat.5 and Cat.5e. While Cat.5 supported fast Ethernet with 100Mbps, it was not suitable for Gigabit Ethernet and therefore holds no substantial place within the market. Cat.5e however, was a cable standard with improved NeXT and FeXT values that is used for 1000BaseT networks. This low-cost standard is popular in the home and prosumer markets and is still widely used.
Category 6 cables belong to connection class E or EA and are therefore also divided into Cat.6 and Cat.6A (Cat.6 Augmented) for the transmission of frequencies up to 250 or 500MHz. Cat.6 cables are mainly used in data networks with multimedia applications and high network load. In order to meet the higher bandwidth requirements for 10 Gigabit Ethernet, Cat.6 cables are used. Cat.6A has been chosen as the category for frequencies up to 500MHz over a maximum of 100m. This means that in modern installations designed for 10GBASE-T you should always find at least Cat.6A cable.
Improved Shielding – Higher Data Rates
Category 7 is divided into Cat.7 and Cat.7A for cables and according to class F and class FA. Defined foroperating frequencies up to 600 or 1000 MHz, this category relies on a cable structure with 4 individually shielded pairs and one overall shield. This improved shielding means that the cables in this category are well equipped for future developments. For the first time, new Cat.7 connectors have been added to the standard, the RJ45 downward compatible Nexans GG45 and the fully shielded TERA connector from Siemon. However, both were not able to establish themselves on the market, Cat.7 cables and modern 10GBASE-T network devices continue to use RJ45.
Category 8, which has not yet been fully adopted, is currently in the starting blocks, with class G, which is divided into the subcategories Cat.8.1 with class I. Cat.8 features RJ45 connectors fully compatible with Cat.6A and Class EA, and Cat.8.2 and Class II, compatible and interoperable with Cat.7A and class FA with RJ45, GG45 or TERA connectors. Cat.8 is designed for a maximum operating frequency of 2000MHz. The cables in this category are suitable for use with the latest Ethernet standards, 25GBASE-T, 40GBASE-T and 100 GBASE-T. Cat.8 cables are typically found in datacentres as short connections between switches and routers due to their shorter ranges.
Network Cables & Their Shielding Types
Unshielded Twisted Pair - U/UTP
Unshielded/Unshielded Twisted Pair – a completely unshielded cable, which is still often used for the lower cable categories Cat.5 and Cat.6 This means that they are usually sufficient for the transmission methods of networks up to Gigabit Ethernet, even if they are not optimal. However, in some cases it may be better to use unshielded cables.
Firstly, if there are large voltage potential differences between the end points of the reference potential and the network devices used are themselves connected to earth or ground potential via the PE contact of the power supply cable, a second earth connection and an earth loop is created. It generates low-frequency compensation currents via the cable shield, which considerably impair the signal quality. Second, some AV or USB extender systems that use Cat.X cables are more dependent on good crosstalk than good shielding and therefore work better with unshielded cables.
Foiled Unshielded Twisted Pair - F/UTP
A F/UTP cable is made up of a U/UTP cable core wrapped in a foil screen made of mostly aluminum laminated plastic foil. For a long time this shielding the type was the most frequently used and is more than enough for Cat.5 and Cat.6 cable categories and for transmission standards up to Gigabit Ethernet, while significantly optimizing the signal quality compared to U/UTP cables.
Screened Foiled Twisted Pair - S/FTP
This shielding type with braided shielding around the cable core and foil shielding around the individual wire pairs is sometimes referred to as PiMF cable (Pair in Metal Foil). It represents the strongest shielding and must be used for some cable categories (Cat.7, Cat.7A, and Cat.8.2). The wire mesh of the overall shield should have a coverage of more than 30% in order to achieve enough shielding against the typically low-frequency (and long-wave) interference.
