A wavelength conversion scheme is presented experimentally using a wavelength tunable erbium-doped fiber laser as a probe light source and an electroabsorption modulator with a DC bias only.For the input wavelength of 1557nm with a 10-Gb/s non-return to zero signal, the Q value is 10.6and the power penalty is less than 1.5dB at a bit error rate of 10–9 at the probe wavelength of1560nm. Given a fixed Q value of 6, probe wavelengths cover a range of 25nm. Furthermore,the relationship between the range of probe wavelength and the amount of power penalty is alsoinvestigated.
