Actually, I think that it takes the exact same amount of noise to flip a bit as it does to transmit a bit. Through the principle of superposition, if you transmit a 0 with X watts, and I transmit a 1 with X watts, our combined signal will be somewhere in the middle, which can cause a bit flip. I am not talking about voltage drop from end to end, which is a separate issue. I am talking about interference occurring adjacent to any point on the cable that you pick.
