Hi all,
I recently had one of my non-technical colleagues ask me an interesting questing - how fast is ethernet data transmitted over a UTP cable? So what he was really asking is "what is the average latency of an electrical signal over copper cabling?". I've done some googling but can't find a definitive answer to this. I know that as a rule of thumb the speed of light is reduced to around 0.66c in a fibre, so you could say that the signal travels through the fibre at 2/3 the speed of light. What is the equivalent for an electrical signal in copper?
Thanks.
Ash.
...note that I'm only asking about the signal propagation time in the cable. The processing delay of the equipment at each end of the cable is a seperate issue.
