Minimum dispersion at 1.55 .mu.m for single-mode step-index optical fibers
 Transmission of wideband data through single-mode optical fibers is feasible due to far less dispersion. The appropriate index difference between the core and cladding and the dimensions of the core diameter are identified and selected to achieve minimum total dispersion at 1.55 .mu.m for single-mode step index fibers. A minimum total dispersion results from a cancellation between the material and waveguide dispersions which is owed to the proper selection of these parameters.
