Optimization Analysis of Transmission Performance of 10Gb/s Optical Signal Using Adaptive Decision Feedback Equalizer

Electrical dispersion compensation equalizer is a cost-effective element in optical communication OOK systems in the presence of chromatic dispersion. The optimization of training sequence and taps for the electrical adaptive decision feedback equalizer in a single-mode fiber communication system is studied in this paper.10-Gb/s transmission over 100 km and up to 180 km of single-mode fiber without any in-line dispersion compensation is demonstrated. The simulation results show that the ISI can be eliminated effectively with the ADFE in the optical single-mode fiber (SMF) communication systems. With a transmission distance up to 180 km without in-line dispersion compensation, present metropolitan area networks can be efficiently upgraded and expanded to accommodate fast development of expanding cities.
