Abstract :
A nonlinear analog modulation scheme, Pulse Frequency Modulation (PFM), is highly amenable to fiber optic transmission, attaining performance characteristics which are attractive in the context of fiber optic tether cables between undersea vehicles and their support platforms. PFM, contrasted with traditional fiber optic modulation techniques, is shown to exhibit superior characteristics for video bandwidth, long haul transmission. A specific hardware realization which employs PFM is presented, and its operating characteristics discussed.
