When the optical fiber is compared to the copper wire, the copper wire _____.
A) has a larger bandwidth
B) is more resistant to signal interface
C) is generally more costly in installation
D) has higher attenuation during signal propagation.
E) offers better signal security.

Question

Quizplus · Accepted Answer

Copper wire has higher attenuation during signal propagation compared to optical fiber due to signal loss from resistance and electromagnetic interference. Optical fiber has a higher bandwidth and offers better signal security, but may be more costly in installation.
