Abstract
The strength reliability of spliced optical fibers is normally characterized using the tensile tests. When the fiber is under two- point bending, the glass surface area under maximum stress is very small and sharply localized, and it would be necessary exactly to situate the splice in that area, because that two-point bending is not used to study the strength of the splices. But an important question is related with the strength of spliced fibers: the strength degradation of the extremities of the fibers stripped during the splice operation. In those small lengths of fiber, around four centimeters, it is possible to use the two- point bending technique. In this work the two-point bending technique was used to measure the extremities strength of spliced fibers and a study of the flaw population presented in that vicinity is made comparing with tensile tests. The splices were prepared using an automatic method to strip, cleave and clean the fiber extremities.
