Abstract :
We experimentally investigate the dependence of semiconductor laser intermodulation distortions (IMDs) on fiber transmission length. IMDs in fiber optic link are degraded over transmission through dispersive fiber. We show that IMDs can be reduced and made less dependent on fiber transmission length by using injection-locked DFB and Fabry-Perot (FP) semiconductor lasers
