The passage around this formula
Modern high-rate Ethernet lanes use PAM4 modulation: instead of encoding one bit per symbol as ordinary NRZ signaling does, PAM4 uses four distinct voltage levels to encode two bits per symbol, so a lane’s bit rate runs at twice its baud (symbol) rate rather than matching it one for one. Writing for the symbol rate and for the resulting line rate,
