Simulation Study and Analysis of High Speed Single Channel Transmission in Optical Communication Line

Design and optical dimensioning of high-speed optical communication lines is a complex task in terms of various limiting factors. The main purpose of this paper is to study and compare RZ- and NRZ- modulation format transmission in single mode fiber at 40 Gbps taking into account the following: group velocity dispersion, self-phase modulation, linear losses, and inserted noise due to periodical amplification. The present study also examines and compares different compensation schemes.
