Splicing and bending losses are compared among step, power-law, W, ring-shaped, and M·W index single-mode optical fibers. A product of normalized offset and tilt misalignments D N Φ N is introduced to compare the permissible offset and tilt misalignments among these fibers. Permissible offset misalignment can be evaluated by D N /B1/3 under constant bending loss condition. Here, B denotes the bending loss parameter. Numerical calculations on these parameters reveal that the required splicing accuracy is nearly identical for step, power-law, and W fibers. An index dip at the core center seems to cause deleterious effects on the splicing loss, provided that the fiber bending loss is kept constant. The effects of profile parameters on D N Φ N and D N /B1/3 are investigated in detail.
