Apparently a fellow named Heaviside established a method of balancing effects of cable's capacitance with effects of its inductance (I am assuming he did it mathematically). This is called Heaviside’s Condition.

Cables in which the ratio of conductance to capacitance equals the ratio of resistance to inductance (G/C = R/L) satisfy Heaviside’s Condition. Companies that use network boxes, such as MIT and Transparent, for example, introduce capacitors, inductors, and resistors in the boxes in part to make the cable satisfy Heaviside’s Condition.

Looking at it electronically, if we cancel out capacitance and inductance-since they are 180 degree opposite of each other, the only thing a signal see traveling thru cable is resistance....theoretically that is :)
