Optimal Modulation Formats for 2560 km Optical Transmission with Low-Power Penalty
Based on the analysis of implementation method of NRZ, RZ and CSRZ formats, the transmission performance of the 10 Gb/s system with these different formats mentioned above was compared by numerical simulation, respectively. In this simulated system the EDFA was used as the solo amplifier and the CFBG was served as the solo dispersion compensator. A practical 8×10 Gb/s transmission experiment with CSRZ formats in straight line was also conducted and only 2.5 dB power penalty was cost after 2560 km transmission with error-free code. The experimental results show CSRZ will help to optimize the performance of the CFBG-based system greatly.
