摘要

本文研究了不同调制格式下具有后色散补偿的DWDM系统。HOA (Raman-EDFA)用于光网络中增加功率传输波长。通过误码率、质量因数、消光比等参数对不同调制格式下增加输入功率的结果进行了比较。结果表明，NRZ(不归零)格式误码率小于10−72，消光比为9.7dB，而RZ(归零)格式误码率低至零，消光比高达13.57dB。分析上述性能参数，可以很容易地得出RZ格式远优于NRZ格式的后分散管理。

Design and performance analysis of dispersion managed system with RZ and NRZ modulation format

In this paper, DWDM system with post dispersion compensation is investigated using different modulation formats. HOA (Raman-EDFA) used to increase the power transmission wavelength in optical network. The result obtained on increasing the input power for different modulation format are compared with the help of parameters like bit error rate, quality factor and extinction ratio. It was observed that NRZ (non-return to zero) format BER is less than 10−72 and extinction ratio is 9.7dB whereas RZ (return to zero) format bit error rate is as low as zero and high extinction ratio of 13.57dB. Analysis the above performance parameters it can be easily concluded that RZ format is much better than NRZ format for post dispersion management.
