主　　题：long haul optical transmission modulate formats CFBG error-free low penalty 

摘      要：The production mechanism of non-return-to-zero(NRZ),return-to-zero(RZ)and carrier suppressed return-to-zero(CSRZ)was analyzed theoretically in this *** compared the transmission performance of CSRZ with RZ and NRZ formats at 10 Gb/s system by numerical *** we simulated the transmission model constructed with Erbium-doped fiber amplifier(EDFA)as the solo amplifier and the chirped fiber Bragg grating(CFBG)as the solo dispersion compensator used in the system.A practical 8x10 Gb/s 2560 km transmitted experiment was conducted in straight line with these different modulation formats mentioned above and the experiment results show very good agreement with the result of computer *** CSRZ format is more effective than other formats in the system,and involved only 2.5 dB power penalty cost in the practical 2560 km error-free *** results also show that CSRZ will help to optimize the transmitted results and reduce the transmitted penalty further.
