D)neither A nor B

Question

Quizplus · Accepted Answer

SONET/SDH lines use optical fiber as the transmission medium for high-speed data and voice communication. This enables fast and reliable communication over long distances with minimal signal loss and interference, making it the preferred choice for telecom carriers and service providers. High-quality forms of data-grade UTP are not used for SONET/SDH lines since they cannot support the required high transmission rates and are susceptible to signal degradation and electromagnetic interference.
