What are two characteristics of fiber-optic cable? (Choose two.)
- It is not affected by EMI or RFI.
- Each pair of cables is wrapped in metallic foil.
- It combines the technique of cancellation, shielding, and twisting to protect data.
- It typically contains 4 pairs of fiber-optic wires.
- It is more expensive than UTP cabling is.
Explanation:Fiber-optic cabling supports higher bandwidth than UTP for longer distances. Fiber is immune to EMI and RFI, but costs more, requires more skill to install, and requires more safety precautions.
