100Mbps isn't exactly a square wave, I believe it's 3 level signalling 
with
shaping to prevent high frequency components (of square waves).

That is right.  100 Meg over copper user ML3T - three levels using 
voltages of
0 volts, +5, and -5.  10 meg uses Manchester encoding running at 20Mhz 
in a
nice "return to zero" square wave.
