Abstract
Split sleeves are essential for fiber-optic connectors. The microscopic deformation of a split sleeve in which two ferrules are inserted generates a gauge retention force related to connector performance. However, Finite Element Method (FEM) analyses of split sleeves was difficult because of their very small deformation and lack of a fixing point between ferrule and sleeve. This paper describes the microscopic deformation of a split sleeve using FEM analysis, which is confirmed by measuring the split width, the split sleeve surface strain using strain gauges, and the attenuation of Angled PC connectors, which varies according to the ferrule endface angle and split sleeve direction.
