Robust WDM transmission and dispersion compensation at 40 Gbit/s over 200 km of standard fibre is demonstrated on a 100 GHz grid using four high power single-polarisation single-sided output DFB fibre laser based transmitters. Simultaneous dispersion compensation of the channels is performed with a single four-channel chirped WDM fibre Bragg grating.
