Question

What are two characteristics of fiber-optic cable? (Choose two.)

a.It typically contains 4 pairs of fiber-optic wires.
b.It is more expensive than UTP cabling is.
c.It combines the technique of cancellation, shielding, and twisting to protect data.
d.Each pair of cables is wrapped in metallic foil.
e.It is not affected by EMI or RFI

Answer 1

Fiber-optic cables are immune to EMI and RFI and generally more expensive than UTP cabling due to material and installation costs.

Step-by-step explanation:

Two characteristics of fiber-optic cable are that it is not affected by electromagnetic interference (EMI) or radio frequency interference (RFI), and it is typically more expensive than unshielded twisted-pair (UTP) cabling.

Fiber-optic cables utilize light to transmit information, which is not susceptible to EMI or RFI, making it an ideal medium for data transmission in environments with high interference. Moreover, the cost of fiber-optic cabling is higher than UTP because of the materials used and the more complex installation process.
