Dispersion compensated 10 Gbit/s transmission over 700km of standard single mode fibre with 10cm chirped fibre grating and duobinary transmitter

Abstract

Using a 10 cm long chirped fiber grating for dispersion compensation and a reduced bandwidth phase alternating duobinary-encoded transmitter, 10 Gbit/s transmission up to 700 km of standard single mode fiber has been achieved. Positioning of the compensating grating at the middle of the link was found to improve the system performance considerably
