Ethernet over XLR works :3
@aurora
how far can it go?

@wolf480pl @aurora

I wouldn't be surprised if this goes far beyond the typical standards because XLR is shielded Coax which, I think, is superior to S/FTP.

The problem is probably the connector, not the cable length itself.

@simon_m @wolf480pl @aurora Not just the shielding, but it's also a balanced line: https://en.wikipedia.org/wiki/Balanced_line

@rojun @wolf480pl @aurora

Yes, I meant balanced line. I couldn't remember the (English) term for this, so I just called it shielding :D

That should *significantly* reduce the noise level, the question that remains is the resistance.

The German Wikipedia goes a little bit more in-depth with the graphics:

@simon_m
so both XLR and high-end USB3 would be Symmetrische Übertragung, differenzielle Signale?
@rojun @aurora

@wolf480pl @rojun @aurora

no, USB does not do symmetrical signalling.

so probably

TP < coax < symmetric signalling < the "star quad" which until today didn't know exists

@[email protected] @[email protected] @[email protected] Good microphone cables are “star quad” (https://en.wikipedia.org/wiki/Star_quad_cable). I don't think I've ever seen coax XLR.

@simon_m @wolf480pl @aurora @rojun @MrDOS ooooh!

Also, one star quad would easily suffice for 100 Mbit/s.

@simon_m
oh, because the super-speed pairs are either a twisted pair in the same shielding as all the other twisted pairs, or they are two individually shielded coaxes, and not a twinax?
@rojun @aurora

@wolf480pl @rojun @aurora

twisted pair or "normal" coax, with one in the middle and one around. Maybe shielded, but I don't think so.

@simon_m
I saw a Xray photo of one that had 2 coaxes for each superspeed pair, both + and - on the inside of each coax, and coax shields joined togeher at the ends and conncted to the ground
