Quizplus · Accepted Answer

SONET is a high-speed communications protocol that is typically implemented using fiber-optic cable. While twisted-pair copper wire and coaxial cable can also be used for high-speed communications, they are not commonly used for SONET networks. Therefore, the best choice for SONET cable is fiber-optic.
