A broad-band continuous-wave (CW) pumped fiber-based parametric amplifier with 49 dB of internal gain and wavelength conversion efficiency, corresponding to a black box gain/efficiency of 38 dB, is demonstrated. Bit-error-rate (BER) measurements indicate performance comparable to erbium-doped fiber amplifiers (EDFAs), These amplifiers may thus find new applications in future lightwave systems.
