The higher the Enet data rate, the higher the frequency content of the signal and the greater the loss, per foot. Go look at the TIA-EIA-568 specification for building cabling. | |

| Dec 10, 2020 at 21:00 | comment | added | Nate S. | IIRC the ethernet signal limit is based on skew -- each pair is twisted at a slightly different rate to minimize crosstalk, but this also means that each pair is a slightly different length. At short distances this doesn't matter, but once the cable gets long enough, the signals from the less twisted pairs start to arrive before the signal from the more-twisted ones, and it stops working. | |

| Dec 10, 2020 at 17:30 | comment | added | Criticizing Israel not allowed | "This is based on the way the Ethernet signal works" - elaborate? USB has a hard length limit based on the speed of light, but I don't think Ethernet relies on round-trip time delay like USB does. | |
