← ScienceWhich risk increases when deploying a fiber optic cable underwater?
A)Increased signal loss from microbending✓
B)Chromatic dispersion becomes insurmountable
C)Polarization mode dispersion intensifies
D)Stimulated Brillouin scattering dominates
💡 Explanation
Increased pressure can cause microbending, exacerbating destructive interference causing signal loss because light scatters and interferes at bends. Therefore, signal attenuation is greater, rather than solely dispersion or scattering mechanisms dominating, given enough bending during the cable laying process.
