Characteristics of fiber optical parametric amplifier (FOPA) with double-pass pump configuration are experimentally investigated. The double-pass pump FOPA exhibits more than two-fold steeper gain slope in comparison to the conventional FOPA due to elongation of effective fiber length. In the L-band amplification band, a secondary idler is generated and used as the transmission signal in lieu of the original L-band signal. Gain measurement and bit error rate experiments are performed on the secondary idler and the results prove the usability of secondary idler, which is potentially useful for distribution networks.
对具有双程泵浦配置的光纤参量放大器（FOPA）的特性进行了实验研究。与传统的FOPA相比，双程泵浦FOPA由于有效光纤长度的延长，其增益斜率陡度增加了两倍多。在L波段放大带中，会产生一个二次闲频光，并将其用作传输信号来代替原来的L波段信号。对二次闲频光进行了增益测量和误码率实验，结果证明了二次闲频光的可用性，这对配电网可能具有潜在的用途。
