Well, I'm not familiar with gigabit Ethernet.  But even using all 4 pairs 
simultaneously means that it might be some combination of serial and parallel 
(I mean, 4 pairs isn't sufficient to carry 8 bits in parallel).

Encoding multiple bits per symbol doesn't (imho) make it parallel.  Just a 
different encoding.
