【Abstract】 The performances of 10 Gbit/s optical transmission system in pre,post and symmetric-compensation are investigated with numerical simulation, and the effects of different compensation values and SPM on transmission system are analyzed. The results show that in the case of post-compesation the performance of proper under-compensation is better than that of full-compensation, but the performances of nearly full-compensation in pre- and symmetric-compensation are best and better than that in pre-compensation.更多还原
