It's going to be long. 60 to 100m I'd bet.You've got speed of light(on copper) divided by bandwidth time or the length of a clock interval
times the number of state changes per byte(datum plus stops and markers) times packet length. I think.

I understood that. Does that make me a nerd?So if I could learn the velocity of propagation over UTP copper, and the oscillation rate of the modulator...
I think I can work it out then. I WAS actually looking at the wrong way :P

It's not going to be the speed of light.Maybe a third, or a half, or two thirds. This depends on something or other to do with wires, I'm pretty sure, yup.

Yeah, on copper makes a big difference.The local speed of propagation/light/energy is slower. 66%ish for rough calculations.

You're mostly right. I used to work in Cable TV, We would see up to 80% for very good coaxial cablingTwisted pair cabling is a bit lower.
