Abstract

Abstract:
Four-wave mixing (FWM) nonlinear effect is used to measure chromatic dispersion
(CD) and polarization mode dispersion (PMD) spatially for different kinds of optical
fiber. The back reflected signal of very high intensity pulses propagated in optical fiber
is detected and one component of FWM products is used to calculate chromatic
dispersion spatially. Then by controlling the state of polarization of launched light into
the fiber under test, it is possible to calculate its PMD spatially.
