So put the same timer mechanism for a fiber optic laser, take even this delay into account, synchronize via GPS, lay it over some 1 or 5km for 2 different places, then check it whether it comes before it was supposed to or not.
You'd need a baseline long enough to obtain a significant result, i.e. much larger than possible measurement errors. So a distance of at least 100 km is required, I think.
fine, then throw out even fiber optics and just use laser between 2 spots(take the delay due to air into account). We only need to test the timing mechanism, all other errors even if present must contribute to less than speed of light, so we only need to consider for the factors which make up distance and time(timing synchronization).
we are only interested in error which results in faster than light calculation, so it must be either distance we got wrong or time. And in the expt, the doubt is in timing mechanism. So we just need to check for the timing mechanism.
