Simple CAT6 cable mod

[Freann]

So shielding is important, but that breaks galvanic isolation, which is more important. Why not both?

 

I realized I could achieve this by simply removing the metal connector shield at one end of a noname CAT6a cable, retaining the cable shield without breaking galvanic isolation.

The effect was greater than expected. Better than optical ethernet? Maybe.

 

Two things…

- The mod process is very fiddly and you will most likely break off the plastic stopping pin, which is irritating. I did this.

- The bloody edges are bloody sharp and you’ll bloody well cut your bloody fingers off. I did this too.

for the lazy people like me blue jean CAT6a is built like that

Is it? I thought they float the shield (not terminated in either end).

Could you please post some pictures?

[Freann]

Yes, will do.

End result (crappy photo from broken iPhone):

 

 

Metal shielding. The middle folded bit is in contact with the cable shield inside the contact. Tricky to remove without breaking things...

thanks

I would like to know as well. I actually have Blue Jean CAT 6a cables in my setup.

If it is CAT6a and the contacts at both ends are not shielded, then the cable shield must be floating.
