We present simple and accurate analytical expressions for transmission coefficient at the splice for both angular offset and transverse offset in case of single-mode dispersion shifted trapezoidal as well as dispersion flattened graded and step W fibers. Here, we employ the recently developed simple series expression for fundamental modal field for such fibers. The evaluation of the concerned parameters based on our formalism requires very little computations. We show that our estimations match excellently with the exact numerical results in case of the said fibers. Further, splices being highly tolerant with respect to longitudinal separation, we restrict our investigations to the cases of transverse and angular mismatches only. The present study should find application in all optical technology involving said kinds of fiber.
