Abstract
Efficiency of PAM, CAP and OFDM/DMT modulation for optical band-limited channels is analyzed theoretically. It is shown that for the same transmitted optical power, and same BER they offer similar data throughputs. However, when the light source has limited dynamics the crucial factor is the peak to average power ratio of the modulating signal. This is the greatest for OFDM/DMT and the least for PAM. Consequently for a given source the average signal power is most limited for OFDM/DMT and least restricted for PAM.
