12,000 km at, for example, 0.4 dB per km
Dispersion sorted. Great.
What about loss? 12,000 km x 0.4 dB/km is 4800 dB.
Anyone else here understand dBs enough to laugh with me? I'm pretty sure that the ratio of 'The Big Bang' itself to a tiny Quantum of energy is significantly less than 4800 dB. Problem is my calculator isn't wide enough, by miles.
