Propagation<br />
Propagation delay is the time it takes a signal to travel from the input of a<br />
system component to the output and is usually measured in nanoseconds.<br />
IEEE 802.3 has specific propagation delay maximums for the Ethernet<br />
components. Cable length plays a major role; i.e., a 50 meters (164 ft.) AUI<br />
cable has a maximum propagation delay of 257 ns. The propagation delay of<br />
cable depends on the length and velocity factor of the cable type.<br />
Round-trip propagation delay throughout the entire cable system, from<br />
farthest ends, may not exceed 51.7 µs, ± 4 µs.<br />
