LAN Connector and Cables

To create a valid collision domain diameter, you must adhere to the
following maximum cable span lengths along with the collision domain
diameter guidelines in Table 15:
■
UTP (running TX or T4)
— Maximum cable span length is
≤
100 m.
■
Fiber (running FX)
— Maximum cable span length is
≤
412 m.
Figure 25 shows examples of collision domain diameters.

Collision Domain Diameter Examples
To determine a valid collision domain diameter, follow these steps:
1
Determine which interfaces will be used: TX, FX, or T4.
2
Add up the combined length of all cabling to be used.
3
Determine which class of repeaters, if any, are used in the collision
domain diameter.
4
Determine the maximum cable length by referring to Table 16, which
contains cabling and repeater guidelines for three scenarios shown in
Figure 26, Figure 27, and Figure 28.
