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

Abstract

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 Bragggratings (FBG) for dispersion slope compensation. It is shown that the FBGeffectively compensate the dispersion slope while at the same time providingappropriate in-line filtering. The penalty to the system performance due tounwanted group delay ripple is also discussed
