Abstract

Abstract In this study, a simulation analysis of 40-Gb/s long-haul (120 km) dense wavelength-division multiplexer system (DWDM) of 32 channels with 50 GHz spacing is conducted for duobinary return-to-zero modulation formats. Pre- and post-dispersion compensation schemes utilizing dispersion compensating fiber (DCF) and fiber Bragg grating (FBG) are analyzed to compare these schemes at high bit rate. Quality factor (Q) and bit error rate (BER) values are used to measure the response of the system as a function of input power for both compensation schemes. The pre-FBG scheme shows a better performance in terms of Q-factor that reached 11.5 at 0 dBm input signal power.
