Abstract :
We measured and analysed four-wave mixing (FWM) efficiency and fluctuation along the actual dispersion-shifted fibers (DSF´s). In the short, 1.1-km DSF, our results agreed with theory, and we also obtained zero-dispersion wavelength /spl lambda//sub 0/, zero-dispersion slope dD/d/spl lambda/, and nonlinear refractive index n/sub 2/ simultaneously. In the long, 23-km, DSF, a high FWM efficiency was observed in the wide wavelength region, due to the longitudinal zero-dispersion wavelength distribution. The fluctuation range was about 3.5 nm and the maximum slope about 1.1 km/nm.<>
