Summary Points

  • Fast Ethernet runs on both twisted-pair and fiber optic cable.

  • 100-meter twisted-pair links are supported for Fast Ethernet.

  • 100BASE-FX and 100BASE-TX have a lot in common, and the pair of technologies has been called 100BASE-X.

  • 100BASE-TX runs on two pairs of Category 5 twisted-pair cabling and supports full-duplex operation.

  • 100BASE-T4 runs on four pairs of Category 3 twisted-pair cabling and does not support full-duplex operation. Data is transmitted on three pairs, and the fourth is used to sense collisions.

  • 100BASE-FX runs on two optical fibers and supports full-duplex operation.

  • 100BASE-TX and 100BASE-FX transmission are based on FDDI and CDDI transmission. All these technologies use 4B/5B encoding.

  • The goal of 100BASE-T2 was backward ...
