Improvement in dispersion tolerance of high-speed fiber optic transmission link by optimization of laser modulation

  • Published:
Opto-Electronics Review

Abstract

In this paper, the improvement in dispersion tolerance of high-speed transmission link with directly modulated laser is presented. The method is based on adopting the laser modulation (its amplitude and depth) accordingly to the dispersion of actual link. As it is shown, the tolerance of negative dispersion may be doubled and of positive increased even seven times. The simulations are proved by hardware experiment, in which the extended dispersion tolerance is demonstrated.
