Cabling Rules and Site Preparation
Although 100Base-T and 10Base-T are alike in many aspects,
there are slight differences in the cabling rules. So, spend some
time in locating and reconfiguring your cabling structure for the
best network layout.
The key cabling rules for 100Base-TX are:
• The 100Base-TX specification requires two-pair Category 5
UTP or two-pair Type 1 STP cable.
• The maximum cable length from an end-station to a hub or
repeater is 100 meters.
• The maximum number of repeater
1
hops allowed is two.
• The maximum network diameter is 210 meters: two
segments of 100 meters with two repeaters/hubs no farther
apart than 10 meters are allowed.
• Switches are not considered as a repeater. Therefore, there
are no limitation to repeater hops or to the network diameter
distance. However, the maximum cable length from an end-
station to a switch still remains at 100 meters.

A single or a stacked 100Mbps hub is counted as one repeater. A
switch is not counted as a repeater, but is treated as an end-station
when applying the topology rules.
