“…A maximum amplification band of ∼100 nm (at 1500 nm) was obtained in optical amplifiers based on only one doped fiber device [6]. Doped fiber optical amplifiers covering the S, C, and L bands (covering ∼140 nm) have already been demonstrated, but as separate devices [7, 8].…”

We present a one‐pump parametric amplifier with polarization independent gain working as an in‐line amplifier within an experimental field‐trial optical network. The polarization independent gain is obtained by using a polarization diversity technique (PDT). Five signals modulated at 10 Gb/s were transmitted through the network, and a gain variation as low as 0.05 dB, independent of the signal polarization, was obtained. The bit‐error‐rate (BER) for the amplified signals was measured. For a BER of 10−9, a power penalty as low as 0.7 dB is shown. These measurements were compared with the identical ones obtained when the parametric amplifier with the PDT was replaced by an Erbium‐doped fiber amplifier (EDFA). The fiber optical parametric amplifier (FOPA) with the PDT presents a power penalty of 0.7 dB in relation to the value obtained with the EDFA. These results show that parametric amplifiers that use the PDT are able to reach a performance comparable to those obtained with the current technology of optical amplifiers based on rare earth doped fibers. © 2013 Wiley Periodicals, Inc.
