Description

ABSTRACT:
A ferrule comprising a molded ferrule body defining fiber bores, an end face of a connective end of the ferrule positioned about the fiber bores, and an integral reference surface for determining the angularity of the end face. The integral reference surface is not machined subsequent to a ferrule molding process and is accessible after assembly of the ferrule body into a connector body. A multi-fiber ferrule comprising a connective end defining an end face, a rear non-connective portion defining a protruding shoulder, and an integral reference datum positioned on a surface of the shoulder accessible for determining the angularity of a plane defined by the end face, wherein the integral datum is accessible when the ferrule is received within a connector body.
