Abstract :
The wavelength emitted from a 2.5 Gbit/s integrated electroabsorption modulator/DFB laser module is tuned over 3.2 nm via the chip temperature control, while sensitivity penalties caused by the chromatic dispersion of 770 km standard fibre remain <1 dB. This significantly relaxes the manufacturers´ constraints on the wavelength specifications in the scope of multichannel systems
