LAN-Kabel

Over the past several years, local area (LANs) have become commonplace in business and manufacturing facilities. Local area networks (LAN's) now connect a vast number of personal computers, workstations, printers, and file in the modem office. Local area networks (LANs), such as ethernet or token-ring networks, are generally coupled via hubs. A hub is a system made of LAN adapters that communicate via a switch card. Ethernet is a LAN networking protocol commonly utilized today. Ethernet typically utilizes a "star" or "spoke" topology, where each computer of the LAN is connected to other computers via a central hub. A LAN system is typically implemented by physically connecting all of these devices with copper-conductor twisted-pair LAN cables, the most common being an 8-wire cable which is configured as 4 twisted-wire pairs. A twisted pair cable includes at least one pair of insulated conductors twisted about each other to form a two-conductor group. When more than one twisted pair group is bunched or cabled together, it is referred to as a multi-pair cable. High performance twisted pair cables have become popular for a variety of reasons. Such cables are comparatively easy to handle, install, terminate and use. They also are capable of meeting high performance standards. The twisted pair cables must meet specific standards of performance in order to efficiently and accurately transmit the data between the communication devices. LAN cables sometimes include a flexible foil wrapper that acts as an electrostatic shield. Each end of the LAN cable is terminated in an industry-standard connector.
