Compensation of third-order dispersion in a 100 Gb/s single channel system with in-line fibre Bragg gratings

This paper presents a scheme to enhance the performance of an ultrahigh capacity (100 Gb/s) long haul transmission system that makes use of chirped fibre Bragg gratings (FBG) for dispersion slope compensation. It is shown that the FBG effectively compensate the dispersion slope while at the same time providing appropriate in-line filtering. The penalty to the system performance due to unwanted group delay ripple is also discussed.
