S. Nishi et M. Saruwatari, TECHNIQUE FOR MEASURING THE DISTRIBUTED ZERO DISPERSION WAVELENGTH OFOPTICAL FIBERS USING PULSE AMPLIFICATION CAUSED BY MODULATION INSTABILITY, Electronics Letters, 31(3), 1995, pp. 225-226
A novel method for measuring the distributed zero dispersion wavelengt
h lambda(0) along a fibre's length is proposed that uses the dispersio
n dependent amplification induced by modulation instability. The lambd
a(0) distribution of a 10km fibre is successfully measured without cut
ting the fibre into short pieces. The measured distribution is compare
d with the average values of each span as measured with the convention
al method.
