Abstract :
Pulse amplitude modulation (PAM) and discrete multi-tone (DMT) technology are attractive modulation techniques for short-reach applications of the next-generation optical transmission systems. We have simulated and experimentally measured and compared the transmission characteristics of PAM and DMT by using the same simulation model and the same experimental setup. Consequently, we have confirmed that DMT has an advantage over PAM.
