Fast Ethernet

Fast Ethernet can meet the growing demand for network traffic speeds. 100Mbps Fast Ethernet standards are divided into: 100BASE-TX, 100BASE-FX, 100BASE-T4 three sub-categories. Fast Ethernet technology can effectively protect the user's investment in cabling infrastructures, it supports 3,4,5 twisted pair and fiber optic connections, and can effectively use the existing facilities.
With the development of the traditional standard Ethernet technology has been difficult to meet the growing demand for network traffic speeds. 1993, 10 months ago, more than 10Mbps for data traffic requirements of LAN applications, only the Fiber Distributed Data Interface (FDDI) to choose from, but it is a very expensive price, based on 100Mpbs cable LAN.
 October 1993, Grand Junction has launched the world's first Fast Ethernet hubs and network interface cards FastSwitch10/100 FastNIC100, Fast Ethernet technology can be applied formally. Then Intel, SynOptics, 3COM, BayNetworks and other companies have also launched their own Fast Ethernet devices. At the same time, IEEE802 engineering group also 100Mbps Ethernet standards, such as 100BASE-TX, 100BASE-T4, MII, repeater, duplex and other standards were studied.
March 1995 IEEE announced the IEEE802.3u 100BASE-T Fast Ethernet standard (Fast Ethernet), so began the era of fast Ethernet.
100Mbps Fast Ethernet bandwidth with the original work in FDDI than it has many advantages, mainly reflected in the Fast Ethernet technology can effectively protect the user's investment in cabling infrastructures, it supports 3,4,5 twisted pair and fiber optic connections, and can effectively use the existing facilities.
 Fast Ethernet, Ethernet technology is actually less than the deficiency, that is, Fast Ethernet is still based on Carrier Sense Multiple Access and Collision Detection (CSMA / CD) technology, when the network load is heavy, it will result in efficiency reduction, of course, exchange technology can be used to make up.
