Theoretical Splice Loss Study Of Single-Mode Fibers

A thorough understanding of single-mode splice loss mechanisms is necessary to accurately predict the resultant splice loss of selected fiber pairs. Given a fusion splicing technique, which yields low variations of extrinsic splice losses, the intrinsic loss factors may be examined. In this paper, the method of calculating intrinsic losses due to fiber mode field radius mismatch and core lateral offset will be reviewed, and the theoretical losses of 10,000 randomly selected fiber pairs are presented. Splice loss data for arc fusion spliced pairs are correlated with the theoretical loss predictions.
