POLARIZATION MODE DISPERSION IN DISPERSION-SHIFTED FIBERS - AN EXACT ANALYSIS

Using an exact waveguide analysis and measured stress profiles, we show that a delicate interplay between form induced and stress-induced contributions to polarization mode dispersion in dispersion fibers can significantly reduce intrinsic short-length polarization mode dispersions. Our observations also indicate that the ovality of fibers is not a true indicator of long-length polarization mode dispersion in production-quality cabled fibers.
