“…A re‐circulating loop experiment involving fiber OPAs was presented in Refs. . However, the OPA was placed outside the loop and its operation as in‐line amplifier was emulated by degrading its input signal‐to‐noise ratio.…”

“…9, No. 1 (2015) 51 As their name indicates, fiber OPAs can in principle amplify optical communication signals. Just as EDFAs and DRAs, they can handle any modulation format, from binary modulation (on-off keying and binary phase-shift keying) to high-order amplitude and phase modulation formats, such as quadrature amplitude modulation (QAM), and amplify wavelength division multiplexed (WDM) signals.…”

The prospects for using fiber optical parametric amplifiers (OPAs) in optical communication systems are reviewed. Phase-insensitive amplifiers (PIAs) and phase-sensitive amplifiers (PSAs) are considered. Low-penalty amplification at/or near 1 Tb/s has been achieved, for both wavelength- and time-division multiplexed formats. High-quality mid-span spectral inversion has been demonstrated at 0.64 Tb/s, avoiding electronic dispersion compensation. All-optical amplitude regeneration of amplitude-modulated signals has been performed, while PSAs have been used to demonstrate phase regeneration of phase-modulated signals. A PSA with 1.1-dB noise figure has been demonstrated, and preliminary wavelength-division multiplexing experiments have been performed with PSAs. 512 Gb/s have been transmitted over 6,000 km by periodic phase conjugation. Simulations indicate that PIAs could reach data rate x reach products in excess of 14,000 Tb/s × km in realistic wavelength-division multiplexed long-haul networks. Technical challenges remaining to be addressed in order for fiber OPAs to become useful for long-haul communication networks are discussed.

“…This is because large interchannel crosstalk was reported due to FWM (four-wave mixing) interactions within the WDM bands enhanced by the presence of the strong pump wave [2]. However, there are several successful demonstrations of multi-channel amplification with small degradations [3,4]. The key for these experiments is the operation with low WDM bands input powers and a large pump power because this effectively reduces the crosstalk [5,6].…”
