On a CAT 7 Ethernet cable each twisted pair is individually shielded, and all pairs together are inside a shielded jacket:
Colors of the wires may change, for instance I recently got my hands on a cable where the wires were all different:
- red & orange
- yellow & brown
- white & blue
- black & aqua
When crimping a RJ-45 plug, should we follow the same order as in 568B, i.e. the four twisted pairs go to pins 1-2 4-5 7-8 3-6, as in the figure...
... or any order of the wires (provided they match at both cable ends, of course) will work fine?
In a CAT 7 cable, a wire is protected from crosstalk from its pair because of the twisting, and is protected from crosstalk from all other wires because of the double shielding, so I'd lean towards the second option.
