  • FIBER OPTIC CONNECTORS AND ASSOCIATED ADAPTERS
    Publication number: 20210263226
    Abstract: A fiber optic connector having a ferrule that forms an optical connection with another fiber optic connector. An outer housing supports the ferrule and has a front end portion and a longitudinal centerline axis. The front end portion includes a front end face with a portion of the ferrule being forward of the front end face. The front end portion includes a protector that is shaped and arranged to protect the ferrule. The protector is arranged so that the fiber optic connector and another fiber optic connector of identical construction can, starting in the same orientation, be mated together by rotating said other fiber optic connector 180° about an axis perpendicular to the longitudinal centerline axis, aligning the longitudinal centerline axes and moving the fiber optic connectors along the longitudinal centerline axes until the fiber optic connectors are mated to form the optical connection.

  • Inspection Tip Having a Self-Adjusting Prism for an Optical Fiber and Method of Use
    Publication number: 20210215572
    Abstract: A ferrule endface inspection tool with a straight tip is provided. The tool deploys a wedged prism at the inspection end or the end of the tool nearer the ferrule endface. The prism endface is cut at an offset angle of about eight degrees and thus allows light exiting the prism to enter the ferrule end face with an opposing APC ferrule tip. Since the entry is at zero degrees into the opposing APC ferrule endface then under Snell's Law there is no theoretical signal loss, and the returned or reflected light signal is imaged at no loss.
