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.

光通信系统中的光纤参量放大器。

回顾了在光通信系统中使用光纤参量放大器（OPA）的前景。考虑了相敏放大器（PIA）和相敏放大器（PSA）。对于波分和时分复用格式，已经实现了/或接近1 Tb / s的低惩罚放大。高质量中跨频谱反演已证明为0.64 Tb / s，避免了电子色散补偿。已执行幅度调制信号的全光幅度再生，而PSA已用于演示相位调制信号的相位再生。已经证明了具有1.1dB噪声系数的PSA，并且已经使用PSA进行了初步的波分复用实验。周期性相位共轭已在6,000 km上传输了512 Gb / s。仿真表明，在现实的波分多路复用长距离网络中，PIA可以达到数据速率x达到超过14,000 Tb / s×km的乘积。为了使光纤OPA对长距离通信网络变得有用，还讨论了仍需解决的技术挑战。
