Question 14: What are the three main components in the
anatomy of a fiber?
CORRECT ANSWER: Core, Cladding, Coating
Question 15: What is attenuation?
CORRECT ANSWER: The decrease in magnitude of
transmission signal strength between points, expressed in decibels as the ratio of output to input signal
Question 16: What is attenuation (insertion loss) in the
context of fiber optics?
CORRECT ANSWER: Light pulses traveling along fiber
are subjected to loss due to absorption or scattering of the light
Question 17: What is intrinsic attenuation?
CORRECT ANSWER: Controlled by the manufacturer,
expressed in decibels per kilometer, impacts the signal to reach the receiver with sufficient power
