The combined effects of chromatic dispersion, selfphase modulation and laser chirp are numerically investigated for a 10 Gbit/s IM-DD system over 100 km of standard single-mode fiber. Fiber based pre-and postcompensation of the chromatic dispersion is compared. The results show that partial post-compensation of the chromatic dispersion yields low eye opening penalty and the penalty is power independent over a very wide power range.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
