Fast Ethernet
Fast Ethernet is based on the Ethernet
standard yet runs at 10 times the speed
(100 Mbps). It is now one of the most
popular high-speed technologies because
of its cost effectiveness, stability, and
compatibility with existing Ethernet
LAN environments. Fast Ethernet
switching allows dedicated performance
between two devices.
The total length of cable (A+B+C
below) between two workstations
and a nonrepeater piece of equipment
(such as a switch) must not exceed
205 m (672 ft). Each cable (A, B, or C)
must not exceed 100 m (328 ft).
3Com recommends using Category 5
cables and that the cable (B) between
the Fast Ethernet hub is not longer
than 5 m (16.4 ft). This allows the
maximum hub-to-workstation cable
length (A or C) of 100 m (328 ft) to be
used, as shown.
