Abstract : Single-mode, step-index optical fibers can be fabricated which enable the wideband long-distance duplex transmission of data at 1.3 micron and 1.55 micron, where attenuation and dispersion are both minimized. The appropriate index difference between the core and cladding materials and the dimensions of the core diameter are identified and selected to achieve minimum total dispersion at three discrete wavelengths in the single-mode, step-index fibers. The three minimum total dispersion wavelengths result from a cancellation between the material and waveguide dispersions which is owed to the proper selection of the parameters. (Author)
