Modern world is the world of internet which requires more capacity and more bandwidth to modernize the world. Hence we move towards optical communication. When we talk about optical communication then chromatic dispersion is biggest obstacle for high speed optical channel. Chromatic dispersion can be reduced either by compensation technique [1, 2] or either by electronic dispersion compensation. In this paper, we make comparative analysis in RZ and NRZ line encoding over 40 Gbps system. Two different modulation formats including non-return-to-zero (NRZ), return-to-zero (RZ) is compared on the basis of Bit error rate and quality factor. The 40 Gbps signal is transmitted over 200 km in single mode fiber.
