Effects of fiber length on the threshold and conversion efficiency of modulation instability
首发时间:2012-11-19
Abstract:The thresholds of modulation instability (MI) in the 25 km, 50 km and 75 km single-mode fibers (SMFs) are investigated by analyzing the MI spectra. They decrease with the effective fiber length and agree with the theoretical values. It is found that the saturation power of MI does not change with the fiber length and is fixed at 136 mW for the three fibers. However, the maximum conversion efficiency of MI depends on effective fiber length. It is revealed that the 15 km and 20 km effective lengths correspond to the maximum conversion efficiency of 50% and 65%. The results provide guidance for the practical applications of long-haul fiber sensing systems.
