One of the few reasons I know for directionality of a cable is if they only ground the wire internally at one end. They mark the direction so that you put the correct ground in place.
Cable Current Flow Direction
Regarding cables that do not have an arrow indicating the current flow from the source to the next component in the chain:
I consider the labelled or banded end of an interconnect cable to be the source end. Is this the generally accepted norm? Some cables are just plain. But when you purchase cables with a band or label at one end, often this means something, but they rarely tell you what. Somewhere along the way I think someone told me that this is the source end. Thank you!
