Abstract
With low chirp direct modulation of a commercially available γ = 1.55 μm 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.Keywords
