Fast Ethernet is an extension of the 10-megabit Ethernet standard. It runs on twisted pair or optical fiber cable in a star wired bus topology, similar to the IEEE standard 802.3i called 10BASE-T, itself an evolution of 10BASE5 (802.3) and 10BASE2 (802.3a). Fast Ethernet devices are generally backward compatible with existing 10BASE-T systems ...
The speed at which energy or signals travel down a cable is actually the speed of the electromagnetic wave traveling along (guided by) the cable. I.e., a cable is a form of a waveguide. The propagation of the wave is affected by the interaction with the material(s) in and surrounding the cable, caused by the presence of electric charge carriers ...
The cable standard specifies performance of up to 250 MHz, compared to 100 MHz for Cat 5 and Cat 5e. [ 1 ] Whereas Category 6 cable has a reduced maximum length of 55 metres (180 ft) when used for 10GBASE-T , Category 6A cable is specified for 500 MHz and has improved alien crosstalk characteristics, allowing 10GBASE-T to be run for the same ...
Category 5 cable (Cat 5) is a twisted pair cable for computer networks. Since 2001, the variant commonly in use is the Category 5e specification (Cat 5e). The cable standard provides performance of up to 100 MHz and is suitable for most varieties of Ethernet over twisted pair up to 2.5GBASE-T [1][2][3][4] but more commonly runs at 1000BASE-T ...
Each 1000BASE-T network segment is recommended to be a maximum length of 100 meters (330 feet), [5] [a] and must use Category 5 cable or better (including Cat 5e and Cat 6). Autonegotiation is a requirement for using 1000BASE-T [6] according to Section 28D.5 Extensions required for Clause40 (1000BASE-T). [7]
Cable testers are widely available to check these parameters to determine if a cable can be used with 10BASE-T. These characteristics are expected to be met by 100 meters of 24-gauge unshielded twisted-pair cable. However, with high-quality cabling, reliable cable runs of 150 meters or longer are often achievable and are considered viable by ...
During this time, the common-mode voltage is −0.8 V. This signal is designed to provide a minimum of ±100 mV at the end of 152 m (500 feet) of cable. The two wires are denoted A and B. To encode a 0 bit, A>B for the first half of the bit time, and A<B for the second half. A 1 bit is the opposite.
10BASE2 cable end terminator. 10BASE2 (also known as cheapernet, [1] thin Ethernet, thinnet, and thinwire) is a variant of Ethernet that uses thin coaxial cable terminated with BNC connectors to build a local area network. During the mid to late 1980s, this was the dominant 10 Mbit/s Ethernet standard. The use of twisted pair networks competed ...
