← ScienceWhich risk increases when long undersea telecommunication cables experience seawater intrusion?
A)Increased signal attenuation losses✓
B)Elevated data encryption overhead
C)Reduced laser diode lifespan
D)Enhanced quantum entanglement fidelity
💡 Explanation
Seawater intrusion raises conductivity, which affects impedance matching for transmission lines; therefore, signal attenuation losses increase because electromagnetic energy is dissipated through dielectric losses, rather than increased quantum entanglement.
