What is the max speed you can get with RG6? I've never actually

>>58450302
Its maxed out speed is wherever you can no longer distinguish the signal from the noise.

>>58450335
Which is usually around how fast?

>>58450302
It's entirely possible the same copper POTS line from the 2400 baud days is still being used with ADSL. Who knows?

>>58450347
It depends on the connecte devices and distance m8

They make 100Gb QSFP28 twinaxial direct attach cables, which is basically coax with two cores. Granted those cables are normally only several meters long.

>>58450421
Why not use fiber

>>58450302
for what protocol?
you can expect to get around the passband bandwidth of a cable, plus or minus an order of magnitude

>>58450438
It's cheaper for shorter cable runs. QSFP28 SR4 optics are expensive. Two SR4 optics would be around $2000, while a 3M twinax cable is about $100.

>>58450506
Why is it only cheAper for short runs?

>>58450302
about .66c

>>58451157
Because of resistance and noise.

electrical signals over copper are highly dependant on length
USB is limited to 5m or so i believe, longer than that and you need repeaters/hubs.
1 Gbit Ethernet(cat 5) is limited to 100m
go above that and signal quality is so bad you won't get a connection. Longer electrical connections have more noise. PCIe on mainboards is a few dozen cm(a few inches) so it can achieve high transfer rates more easily.
