Simple CAT6 cable mod


Recommended Posts

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.

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

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...

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