Optical fiber cords typically have two fiber strands.This is done to allow ________.
A) redundancy
B) total redundancy
C) half-duplex operation
D) full-duplex operation

Question

Quizplus · Accepted Answer

Optical fiber cords typically have two fiber strands to enable full-duplex operation, allowing simultaneous transmission and reception of data. This is necessary because optical fiber is a point-to-point medium, and without two fibers, communication would be half-duplex, which would limit the speed and efficiency of data transmission. The second fiber also provides redundancy in the event of a fiber break or failure.
