Q.	The insertion losses of the fiber splices are much less than the Fresnel reflection loss at a butted fiber joint.
A.	true
B.	false
Answer» A. true
Explanation: 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.
