Paper Abstract

We present a new technique for simultaneous measurement of chromatic dispersion and Brillouin shift distribution along conventional, single-mode optical fibers used in telecommunications. It is based on performing Brillouin Optical Time Domain Analysis (BOTDA) over the four-wave mixing generated by two low-power pumps (< 10 mW). Unlike others, this technique can measure any arbitrary value of dispersion. With the use of this technique we have obtained consistent, high-resolution and low-noise measurements for both magnitudes. Our measurements indicate a certain correlation betwen the spatial distribution of both quantities, although the degree of correlation varies for the different manufacturers tested.
