Main advantage of coaxial cable has over twisted paired cable is to operate:
Correct answer: B. High frequencies
- A. Low frequencies
- B. High frequencies
Explanation
Coaxial cable has several advantages over twisted-pair cable, but one of the most significant is its ability to operate at higher frequencies. This is due to the superior shielding of coaxial cable.Coaxial cable consists of an inner conductor surrounded by an insulator, a braided metal shield, and an outer jacket. The braided shield helps to block electromagnetic interference (EMI) from external sources, which can degrade the signal quality. This shielding allows coaxial cable to transmit signals over longer distances with less signal loss compared to twisted-pair cable.Twisted-pair cable consists of two insulated wires twisted together. While this twisting helps to cancel out some EMI, it is not as effective as the shielding in coaxial cable. As a result, twisted-pair cable is more susceptible to signal interference at higher frequencies.
