← ScienceWhich outcome affects signal integrity when fiber optic cables traverse extreme spacetime curvature?
A)Increased material refractive index
B)Gravitational lensing distorts light✓
C)Chromatic dispersion becomes amplified
D)Modal birefringence averages uniformly
💡 Explanation
Gravitational lensing occurs because spacetime curvature bends light paths nonuniformly. This alters signal propagation through the fiber, therefore distorting transmitted signals rather than affecting material or waveguide properties, due to extreme gravity.
