I'd like to know how far we can push Fios without amps.
The answer is you purchase the proper test equipment and know something about CATV design. But the real answer is that there is no "we", that's Verizon's responsibility. Run your cable as always and let them handle the rest.
I wonder if Verizon knew what they were getting into with Fios and every "expert" screwing with their installs.
