Design and simulation of a optical communication system with dispersion managed RZ pulse

This paper reports the design and simulation of a 10Gbps optical communication system with dispersion managed RZ pulse. The return-to-zero (RZ) format is very efficient for long haul, high bit rate, low power and wavelength division multiplexed (WDM) optical communication system. In RZ format, the power is transmitted only for a fraction of bit length. The effect of altering dispersion parameter of a single mode fiber on the optical communication link has been reported. The analysis has been performed in terms of bit error rate, Q-factor, optical spectrum analysis and average eye opening. It is observed that as the value of dispersion parameter is increases, the Q-factor and the average eye opening also increases. It is also observed that the timing jitters decreases with the increase in dispersion parameter. It is also shown that by reducing the duty cycle, performance of the system is enhanced.
