Abstract :
The authors investigate dispersion penalties in an analogue link using an uncoded Fabry-Perot laser operating near 1.3 μm. Mode-partition noise caused by mode fluctuations combined with dispersion can rise significantly as the laser temperature rises and therefore its wavelength drifts. It is found that in a link transmitting signals near 1 GHz the noise may rise by over 20 dB even though the laser wavelength is close to the dispersion zero of the fibre
