Abstract :
With low chirp direct modulation of a commercially available lambda =1.55 mu m BH DFB laser module at 10 Gbit/s, a transmission experiment over 69 km of non-dispersion-shifted singlemode fibre was successfully performed. The scheme is based on optical FM by modulation of the injection current with subsequent conversion into intensity modulation by means of a fibre Mach-Zehnder interferometer.
