Geoffkait: Whoa! Easy, big fella. I’m not talking about shielded cables.
to which jujitsu replied,
"If it's not about the shield on a STP Ethernet cable, then it's not going to be anything else.
Ethernet is either wired TIA586A or TIA586B straight through, or 586A on one end 586B on the other end for cross over.
Most horizontal run will be CCA, patch is stranded (for better strain resistance and flexibility). Save yourself the laughable argument with grain structure, crystalline structure, etc...
Ethernet is bidirectional."
>>>>>>All wire is bidirectional inasmuch as one can send voice and data over it in either direction. But as fate would have it wire is audibly better in one direction than the other. Even shielded cable that is "directional" sonically according to the shield terminations points is also "directional" sonically according to the direction of the copper conductor. So, it would help to keep track of both aspects of the cable construction. Follow?
