  1. Fiber optics-
    Fiber provides an extremely secure transmission medium, as there is no way to detect the data being transmitted by “listening in” to the electromagnetic energy “leaking” through the cable, as is possible with traditional, electron-based transmissions. By constantly monitoring an optical network and by carefully measuring the time it takes light to reflect down the fiber, splices in the cable can be easily detected.

    It has extremely high bandwidth. It is esistant to electromagnetic interference – Fiber has a very low rate of bit error (10 EXP-13), as a result of fiber being so resistant to electromagnetic interference. Fiber-optic transmission are virtually noise free.

    The disadvantages is that it has high installation cost, special testing is required and Scattering occurs when there are imperfections in the fiber. It is also susceptible to physical damage.
