    Which of the following cables can transmit data at high speeds?                   

    A)  Flat cables       

    B)  Coaxial cable

    C)  Optic fibre cable

    D)  Twisted pair cable

    E)  UTP cable

    Correct Answer: C

    Solution :

    [c] Optical fiber cables are used for high-speed transmission of data without any error. Unlike wire cables, fiber optic cables are not subject electrical interference. They support extremely high band widths because they are limited by the high-frequency photon properties of light rather than by lower ?frequency properties of electrical system. Current technologies allow data rates from 100 Mbps to over 2Gbps (Information Technology Today by S. Jaiswal)
