【Abstract】 Optical orthogonal frequency division multiplexing(O-OFDM) is currently a hot topic in optical communication research over the last couple of year.The application of OFDM in fiber optical communication has shown virtues such as high spectrum efficiency,expedient and effective dispersion compensation,reducing system nonlinear markedly and so on.This paper introduces the basic principle,development and relevant research results of O-OFDM,analyses its advantages and problems of applications,and finally discusses several applications of the commercialization of O-OFDM.更多还原
