Abstract :
Theoretical calculations together with measurements of the chirping characteristics of DFB lasers have revealed the existence of optimum bias condition for longer transmission distance. Ultimate transmission distances in connection with fibre loss and dispersion are estimated for 1.3 and 1.5 ¿m transmission on the basis of experimental device characteristics.
