Splice loss and mode conversion have been studied theoretically for a multimode fiber. Equations have been derived using electromagnetic theory for calculating splice loss and mode conversion in the general multimode fiber. Numerical examples are given for a square-law index fiber in both arc-fusion splice and V-groove splice cases. The influence of the refractive-index profile at the splice on splice loss and mode conversion coefficient is shown. The change in baseband frequency response due to mode conversion at splice is calculated.
