Abstract
In this paper we present a comparative study of the equalization enhanced phase noise (EEPN) for pre- and post-compensation of chromatic dispersion in high capacity and high constellation systems. This is to our knowledge the first detailed study in this area for pre-compensation systems. Our main results show that the local oscillator phase noise determines the EEPN influence in post-compensation implementations whereas the transmitter laser determines the EEPN in pre-compensation implementations. As a result of significance for the implementation of practical longer-range systems it is to be emphasized that the use of chromatic dispersion equalization in the optical domain e.g. by the use of dispersion compensation fibers eliminates the EEPN entirely. Thus, this seems an efficient solution for such systems operating at high constellations in the future.
