In UTP cables larger than 600 pairs, what encases the conductors?

• A. Copper braid
• B. Aluminum-steel shield
• C. PVC jacket
• D. Ethernet skin

Answer: (B)

When many pairs are packed into one UTP cable, interference and crosstalk become bigger concerns. To protect the dense bundle, a metallic shield is added around the conductors, and in this case the shield used is an aluminum-steel shield. This shield provides EMI protection and helps hold the bundle together, which is why it encases the conductors in large (>600 pairs) UTP cables. The PVC jacket is simply the outer covering of the cable, not the shield around the conductors, and copper braid or nonstandard terms like “Ethernet skin” aren’t used for this purpose.
