← ScienceWhich risk increases when optical fiber coatings degrade?
A)Increased modal interference in the fiber✓
B)Increased Raman scattering within the core
C)Decreased chromatic dispersion compensation effects
D)Decreased four-wave mixing signal strength
💡 Explanation
As coatings degrade, increased surface irregularities cause greater unintended reflections within the fiber; this increases modal interference because additional modes propagate, therefore causing signal distortion, rather than simply power loss or wavelength shifts within the system
