Fast Ethernet Topology Rules

APPENDIX A

In the next illustration, the network topology is extended to a

maximum distance of 491 meters (1610 feet). In this network, a 160

meter (524 feet) fiber link connects the 100BASE-TX repeater to the

switch, and a 131 meter (429 feet) fiber link connects the 100BASE-

T4 repeater to the switch. 100 meter (328 feet) Category 5 UTP

wiring connects workstations and servers to the repeater stacks. The

100BASE-TX collision domain is 260 meters (852 feet), and the

100BASE-T4 collision domain is 231 meters (757 feet). When the

two collision domains are interconnected through the switch, the

network topology is extended to a total of 491 meters.

If you’re using a 100BASE-FX Uplink Module in a 100BASE-T4

stackable hub, fiber cable length is limited to 131 meters. If you’re

using a 100BASE-FX Uplink Module in a 100BASE-TX stackable

hub, fiber cable length is limited to 160 meters. If a stack combines

100BASE-TX hubs and 100BASE T4 hubs, fiber distance is limited to

131 meters.
