Abstract :
WDM transmission and demultiplexing of 4 directly-modulated DFB lasers at 2.5 Gbit/s, with very narrow channel spacing (50 GHz) over 3000 km of dispersion-shifted fibre has been performed using a single-span recirculating loop. A high-performance free-space concave grating demultiplexer is used, for the first time, in a WDM transmission experiment
