collapsed backbone). For example, a 225 m (738 ft) fiber link from a
repeater to a router or switch, plus a 100 m (328 ft) UTP link from a
repeater out to the endstations.
The Switch provides full duplex support for all its ports, including
Expansion Module ports. Full duplex allows packets to be transmitted and
received simultaneously and, in effect, doubles the potential throughput
of a link.
With full duplex, the Ethernet topology rules are the same, but the Fast
Ethernet rules are:
Maximum UTP cable length is 100 m (328 ft) over Category 5 cable.
■
A 2 km (6562 ft) fiber link is allowed for connecting switch-to-switch,
■
or endstation-to-switch.
