Abstract
An alignment system is disclosed in a connector ferrule for a fiber optic cable which includes at least one optical fiber. A ferrule body receives the cable and includes a fiber passage for receiving the optical fiber. A pin passage in the ferrule body is spaced from the fiber passage for receiving an alignment pin projecting from the ferrule body to align the body with an appropriate complementary connecting device. An alignment bushing is disposed in the pin passage for directly receiving the alignment pin. The outside dimensions of the bushing are smaller than the inside dimensions of the pin passage to define a space therebetween. A filler adhesive is applied in the space between the outside of the alignment bushing and the inside of the pin passage. Therefore, the bushing can be precisely aligned in the pin passage from exteriorly of the passage, and the filler adhesive can fix the bushing in that precise alignment interiorly of the passage.
