Is there a standard arrangement for the pairs inside a Cat7|6|5 Ethernet Cable?

As shown in the picture, they are in the sequence Orange-Green-Brown-Blue, or the Orange Brown always as opposite pairs, but I have not reach any solid confirmation for this; even, I have found contradictory sketchs, some with Orange-Brown as opposite pairs as here, others as close pairs.

If positive, the cross bone structure in Cat6 should kept that arrangement in a Cat7|6, but should one expect that arrangement to be kept in a Cat5, where no structure is between the pairs?

Thanks in advance.

There is no 'structure' between the pairs in the cable.

What you can guarantee is that white/x will be twisted with x/white.

Isolation between the pairs is enhanced by giving each pair a different number of twists per unit length. This avoids the stray electromagnetic coupling between pairs growing as the length grows.

    \$\begingroup\$ Is the number of twists per unit length related to the colour of each pair? \$\endgroup\$ – Huisman Apr 1 at 9:07

    \$\begingroup\$ Maybe, for any given manufacturer it would make sense. But AFAIK, there is no standard that relates colour to twists. \$\endgroup\$ – Neil_UK Apr 1 at 9:57

    \$\begingroup\$ you can't guarante white/x - x/white there is a (rare) 8-colour option \$\endgroup\$ – Jasen Apr 2 at 20:01

    \$\begingroup\$ twiste mat vary along the length of the wire, or be constant and different for each pair. doing it lengthwise reduces skew on long runs. \$\endgroup\$ – Jasen Apr 2 at 20:04
