Zion communication is a Lan cable manufacturer and cable solutions, supplier
provides network cables from short-run applications to the most critical long-distance Application
Our network cables offer optimum performance for main distribution use in
data center systems where extended cable runs are required.
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 referenced to actual test data verifying high performance.
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 can also be, for example, 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.
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 held no critical place within the market. Cat.5e was a cable standard with improved NeXT and FeXT values 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 divided into Cat.6 and Cat.6A (Cat.6 Augmented) for transmitting frequencies up to 250 or 500MHz. Cat.6 cables are mainly used in data networks with multimedia applications and high network load. To meet the higher bandwidth requirements for 10 Gigabit Ethernet, Cat.6 cables are used. Cat.6A has been chosen for frequencies up to 500MHz over 100m. This means that in modern installations designed for 10GBASE-T, you should always find at least a Cat.6A cable.
