Mitigation of chromatic dispersion effects employing electroabsorption modulator-based transmitters

In this letter, it is shown that the dispersion-induced carrier suppression effect in externally modulated 1550-nm analog fiber-optic links may be mit igated by properly adjusting the chirp parameter of an external electroabso rption modulator. It is theoretically modeled and experimentally demonstrat ed that a significant increase on the frequency-length product of fiberopti c links is achieved with this chirp-adjusting technique, when compared to t raditional methods.
