Abstract :
A novel all-fibre tunable delay-line filter, with a simple structure based on two 3×3 fibre couplers and only one phase shifter is utilised for residual dispersion compensation in a 40 Gbit/s optical transmission system. In this experiment the dispersion tolerance of the receiver was successfully enhanced by 100 ps/nm.
