Abstract
In order to study the influence of third-order dispersion ( TOD) on transmission property of phase-shaped nonreturn-to-zero (PSNRZ) codes, the effect of TOD on the Gaussian pulse with initial chirps was simulated at first, and it was found that the initial chirps could greatly aggravate the effect of TOD on the shape evolution. Then the transmission characteristics of the PSNRZ codes were simulated, and it was found that the transmission distance of PSNRZ codes might decrease severely if the TOD was not compensated, the decreased distance was even longer than 500km when the remained group-velocity dispersion (GVD)was below 20ps/nm. The results show that the TOD must be compensated in the case that PSNRZ code is used.关键词
