Full-Duplex Operation

Full duplex is a transmission method that allows a network

device to transmit and receive concurrently. This mode is sup-

ported by some 10BASE-T and 100BASE-TX switches and net-

work cards, but not by hubs or by 100BASE-T4 devices.

Connecting a pair of devices that can operate in full-duplex

mode eliminates collisions and effectively doubles the band-

width of that segment. In addition, full-duplex operation can

also be used to extend Fast Ethernet fiber cabling distances.
