| Ethernet, Fast Ethernet, & Gigabit Ethernet Distances Use
the shared columns when using hubs/repeaters.
Use the point-to-point columns when connecting end-stations (e.g., switches, routers,
PCs).
All lengths given are the maximum allowed.

* Includes the equivalent 90 meters delay that each normal Class II repeater adds to
the length.
FastHub 100s have an equivalent 90 meters delay.
FastHub 300s have an equivalent 82 meters delay.
For Class II Fast Ethernet repeaters,
The maximum number of repeaters is 2. Each repeater counts as 90 meters.
The maximum number of segments is 3
For Class I repeaters, the maximum number of repeaters is 1.
