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.
