← ScienceWhich mechanism increases signal latency in a long-haul communication fiber routed near a high-mass object?
A)Gravitational time dilation✓
B)Chromatic dispersion offset
C)Waveguide bend losses
D)Material absorption maximum
💡 Explanation
Gravitational time dilation impacts signal latency because spacetime curvature slows the passage of time near massive objects; therefore, signals take longer to traverse the fiber, rather than losses or dispersion, which affect signal amplitude and clarity under normal conditions.
