Splice loss arising from differences in fiber structural parameters such as outer diameter, core diameter, and refractive index difference is studied experimentally and theoretically. Practical formulation for splice loss is made as a function of parameter differences between fibers to be spliced. It is found that the experimental splice loss for conventional graded-index fibers is estimated within an error of 0.1 dB. Considering the fabrication yield rate of fibers as well as splice loss, tolerances of the fiber parameter deviations from the optimum values are determined.
