Generation and Performance Analysis of Single Sideband RZ Signal for 40Gb/s Optical Transmission System
40Gb/s光纤传输单边带归零信号的产生和性能分析

A method to generate Single Sideband Return-to-Zero Signal(SSBRZ) is introduced by deriving formulas. One sideband of the generated SSBRZ signal is suppressed more effectively without distortion of the optical pulses. 40Gb/s single channel transmission of Return-to-Zero(RZ) signal, Carrier Suppressed Return-to-Zero(CSRZ) signal and SSBRZ signal over single mode fiber(SMF) are simulated . The results show that SSBRZ is superior to RZ and CSRZ against fiber nonlinearities when chromatic dispersion is completely compensated.
