The topology rules for 100 Mbps Fast Ethernet are slightly different to
those for 10 Mbps Ethernet.
and provides examples of how they allow for large-scale Fast 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.
