Four Wave Mixing in Optical Links Using Quasidistributed Optical Amplifiers
01 January 2001
We investigate efficiency of FWM generation in quasidistributed EDF sections under general power evolution conditions. Measured FWM efficiencies are found to be in a good agreement with newly developed formulae applicable to waveguides with spatially and spectrally varying gain. Inoue's work describing FWM process in multiple amplified spans is generalized. A new theory of FWM generation in optical links amplified by a set of quasidistributed nodes is developed and used to analyze multiple span L-band link.
