CAN bus
Construction and cross-section
A CAN bus cable is a bus cable for CAN networks: one twisted pair in white and brown, a foil shield, a braided shield of tinned copper, a nonwoven tape wrap and a violet jacket.

“Assumed” means: the value does not come from a datasheet but is a usual value or one chosen from a reference.

The model becomes every picture and every film.
One model, every picture.
Taken apart, up close, where it is used: pick a picture or a film of CAN bus. All of them are computed, not photographed, and say nothing about what the cable is approved for.
That leaves the question of what the jacket says.
What the name says.
CAN stands for “Controller Area Network”, a bus system that connects electronic control units. The name says which network the cable is built for, not how it is built.
Sources and assumptions
No datasheet was available for this type. The dimensions follow an existing 3D model and are therefore marked as assumed. The lay length of the pair was chosen.
