Summary :

Ultimate low loss single-mode fibers have been prepared by reducing excess due to structural imperfections as much as possible. Loss mechanisms based on the fabricated fibers have also been analyzed. Transmission loss has been reduced almost down to the intrinsic material loss. Minimum loss was 0.2 dB/km at 1.55 µm. It was made clear that the dispersion can be reduced to zero at this wavelength region by increasing the waveguide dispersion. It has been confirmed that such single-mode fibers are very useful for high capacity and long distance transmission media.
