The insertion losses of the fiber splices are much less than the Fresnel reflection loss at a butted fiber joint.

The insertion losses of the fiber splices are much less than the Fresnel reflection loss at a butted fiber joint. Correct Answer True

The Fresnel reflection loss is usually more because there is no large step change in refractive index with the fusion splice as it forms a continuous fiber connection. Also, some method of index matching tends to be utilized with mechanical splices.
