Abstract :
An analog transmission technique for multichannel TV transmission on fiber using frequency-modulated/time-division multiplexing (FM/TDM) is described and compared with present digital and analog systems. Analysis and simulations indicate that the proposed system has a very low sensitivity to nonlinearities, similar to digital systems, and much better than current frequency-modulated/frequency-division multiplexed (FM/FDM) systems. This permits the use of higher optical modulation depth (as high as digital systems), which results in achieving high signal-to-noise ratio, large power budget, and/or the use of lower cost optical components. Furthermore, a better spectrum efficiency is possible
