The topology rules for 100 Mbps Fast Ethernet are slightly different to
those for 10 Mbps Ethernet.

networks.

The key topology rules are:
Maximum UTP cable length is 100 m (328 ft) over Category 5 cable.
■
A 412 m (1352 ft) fiber link is allowed for connecting
■
switch-to-switch, or endstation-to-switch, using half-duplex
100BASE-FX.
A total network span of 325 m (1066 ft) is allowed in single-repeater
