The simulation of optical OFDM system

A new optical modulation was introduced.Based on the application of orthogonal frequency division multiplexing(OFDM) in optical fiber communication,an optical transmission system was constructed.Compared with the traditional optical communication technology,this system has the stronger ability to resist dispersion of optical fiber.With the OptiSystem software,a simulation was done to analyze the resisted dispersion performance of the optical orthogonal frequency division multiplexing(O-OFDM) technique,and the results show that O-OFDM has the very good application prospects for ultra-long haul and the high-speed optic-fiber communications.
