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.
