In this paper, we have analyzed the performance of our optimized non-zero dispersion shifted fiber with three different test fibers, namely, single mode fiber, conventional non-zero dispersion shifted fiber and dispersion shifted fiber. While comparing the performances of those fibers, our optimized non-zero dispersion shifted fiber has yielded a better quality factor of 5.24 at 2.5 Gbit/s for long haul fiber length of 120 km in the absence of amplification and dispersion compensation. In order to measure the nonlinear impairments of wavelength division multiplexing channel, the quality factor values are measured at the sample channel 193.1 THz for 150 km lengthed fiber with peak input power of 6 dBm. Due to a very large effective area of optimized non-zero dispersion shifted fiber, it delivers a better quality factor of 6.12 compared to the other test fibers. We have also carried out the analysis for higher bitrates and different modulation formats at the transmission end. More phase encoded modulations of carrier-suppressed return-to-zero–differentiated phase shift keying and carrier-suppressed return-to-zero–differential quadrature phase shift keying offered optimum performances for a distance of 120 km at 10 Gbit/s bitrate. By including optical amplifiers, we could achieve a record fiber transmission length of 4000 km at the bitrate of 2.5 Gbit/s which can help the future wavelength division multiplexing optical networks to a great extent.
