Abstract
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.
