Title: INDEXING TOOL, CALIBRATING METHOD, FERRULE ASSEMBLY AND FIBER OPTIC CONNECTOR
Abstract:
In an indexing tool for calibrating a position of an optical fiber (400) in a bore of a ferrule (300), the fiber extends outward from an end surface of the ferrule, the ferrule (300) has a first indexing feature, and the bore is positioned with respect to the first indexing feature. The indexing tool comprises: a second indexing feature (100) shaped to be complementary with the first indexing feature and capable of being mated with the first indexing feature to align them with each other; and an indexing element (200) having an alignment bore (201) for receiving the fiber extending outward from the ferrule, wherein the alignment bore is positioned with respect to the second indexing feature (100), such that when the first and second indexing features are mated and aligned with each other and the fiber (400) is received in the alignment bore (201), the position accuracy of the fiber in the bore of the ferrule with respect to the first indexing feature is calibrated to reach that of the fiber in the alignment bore with respect to the second indexing feature (100).
