Fiber optic point-to-point links show many advantages over conventional wire systems. These include wide bandwidth, long inter-repeater spacing, secure information transfer, elimination of ground loops and electromagnetic pulse problems. A brief discussion is given of fiber optic components, temporal dispersion, link length, and nuclear hardness. Bit error rate results are given for a 400 Mbps NRZ 200 meter fiber optic link. Some practical aspects are given for fiber system installations.
