Abstract
In order to realize the large capacity of ultra-high-speed optical fiber transmission, optical modulation and reuse is one of crucial technology. This article discusses MAMSK modulation format all-optical OOFDM transmission system. The MAMSK modulation format with the method of phase modulation combined with multiple amplitude modulation, at the same time on the signal phase and amplitude modulation information, achieve the goal of lower code rate. All-optical OOFDM multiplexing technology is the electric field of OFDM, half its adjacent subcarrier frequency spectrum overlap, so the spectrum efficiency is very high, is a kind of very potential recovery technology.
