Answers
C.
Chromatic dispersion (CD) and polarization mode dispersion
D.
Small channel spacing
Answers
D.
Small channel spacing
Suggested answer: B

Explanation:

Scattering and absorption are the main reasons for fiber attenuation. Scattering occurs when light bounces off the sides of the fiber, while absorption happens when light is absorbed by the glass or other materials that make up the fiber. Chromatic dispersion (CD) and polarization mode dispersion (PMD) are also factors that can cause attenuation, but they are not the main causes. Small channel spacing can also cause attenuation, but it is a secondary factor and is only significant in certain cases.
