Detailed explanation-1: -In most of the Fast Ethernet applications, the individual devices are connected by twisted-pair copper wires i.e. 100BaseTX (maximum segment length is only 100 meters) and the optical fibers are used for transmission over longer distances (as maximum segment length is 2000 meters of 100baseFX).
Detailed explanation-2: -Category 5e cable is now the minimum recognized cable for data networking applications, as defined by the current standard. Like Category 5 cable, it also is rated for up to 100 MHz frequencies. Additional performance standards enable it to support transmission speeds of up to 1000 mbps ("gigabit Ethernet").
Detailed explanation-3: -100BASE-FX is a physical layer specification for Fast Ethernet over fiber optics using two multi-mode fiber optic strands for both links, reception and transmission. The maximum length is 412 meters for half-duplex connections (to ensure that collisions are detected) or 2 kilometers for full-duplex.
