Category 6 cable

With the widespread and growing use of computers in communications applications, the ensuing volumes of data traffic have accentuated the need for communications networks to transmit the data at higher speeds. Many communication systems utilize high performance cables normally having four pairs or more that typically consist of two twisted pairs transmitting data and two receiving data as well as the possibility of four or more pairs multiplexing in both directions. Cables formed from twisted pairs of insulated conductors are used to transfer communication signals between, for example, components of a local area network (LAN) such as computers, telephones, and other devices. The Telecommunications Industry Association and the Electronics Industry Association (TIA/EIA) have developed standards specifying a number of performance categories that establish requirements for various operating characteristics of a cable. One high-performance standard for 100 MHz cable is ISO/IEC 11801, Category 5 (Cat 5). Additionally, more stringent standards are being implemented for higher frequency cables including Category 6 (Cat 6) and Category 7 (Cat 7), which includes frequencies of 200 and 600 MHz, respectively. Cables utilizing high quality pairs have been produced for use in communication local area networks (LANs) with a maximum useful frequency of 100 MHz. This is called a Level or Category 5 cable. Advancements in technology have contributed to the design and deployment of high-speed communications devices that are capable of communicating the data at speeds greater than the speeds at which Category 5 data cables can propagate the data. The development of the Category 6 standard and its subsequent wide acceptance by the telecommunications industry has raised the transmission requirements for electrical signals in telecommunications cables to a higher level than ever. A category 6 cable must meet requirements for cable impedance and return loss, signal attenuation and delay, crosstalk, etc. Category 6 is a performance classification for twisted pair cables, connectors and systems which is specified up to 250 MHz. A category 6 cable is generally considered a high performance cable and, as such, return loss and crosstalk requirements may be particularly stringent.
