hi
ethernet phy doesnt carry digital signals its pure analog. the digital signals are encoded and are carried in differential format. for this traffic u dont need the ground reference to be carried all along the path of the ethernet. the signal is sensed by the differential amplifier. if u understand the PHY and PCS layers of 100baseT u can find what it is...
for example,
bit '1' is transmitted as '1' in the + line and '0' in the - line
bit '0' is transmitted as '0' in the + line and '1' in the - line
...i think im clear
