Alignment system in a connector ferrule for a fiber optic cable

An alignment system in a connector ferrule for a fiber optic ribbon cable which includes a plurality of generally parallel optical fibers in a line, comprising:

• a ferrule body for receiving the cable and including fiber passage means for receiving the line of optical fibers and a pair of pin passages spaced from opposite sides of the fiber passage means for receiving a pair of alignment pins projecting from the ferrule body to align the body with an appropriate complementary connecting device, the pin passages being in a front face of the ferrule body, and with an opening in the ferrule body remote from the front face and communicating with the pin passages;
• a pair of alignment bushings in the pair of pin passages for directly receiving the alignment pins, the outside dimensions of the bushings being smaller than the inside dimensions of the pin passages to define spaces therebetween;
• and
• a filler adhesive inserted through the opening in the ferrule body into rearward areas of the pin passages and into the spaces between the outsides of the alignment bushings and the insides of the pin passages,
• whereby the bushings can be precisely aligned in the pin passages from exteriorly of the passages and the filler adhesive can fix the bushings in that precise alignment interiorly of the passages.
