Question

Quizplus · Accepted Answer

Fiber optic cable is capable of transmitting large amounts of data over long distances with very little signal degradation or interference. Its high bandwidth capacity makes it the ideal choice for backbone networks. Infrared frequencies are typically used for short range wireless communication, coax cable has limitations in bandwidth, and twisted pair cables are limited by distance and susceptibility to interference.
