Abstract: An aligning sleeve for a bundle of fiberoptic cylindrical fibers which comprises an elongated body formed of rigid material with the body having a fore end and an aft end. A passage is formed within the body extending from the fore end to the aft end with this through passage being hexagonally shaped in transverse section. Six in number of evenly spaced longitudinal corners are formed within the hexagonal shaped opening with each corner adapted to have nested therein a longitudinally oriented fiber. All the remaining fibers of the bundle align with these corner fibers with the result that all fibers in a bundle are located parallel to each other and tightly packed within the through passage.

Abstract: A plurality of different adapters for a fiberoptic termination inspection microscope which permits the microscope to be used with a plurality of cable connectors where each cable connector has one or more cable termini. The purpose of the microscope is to inspect a cable terminus to determine if such is clean and polished in order to insure low attenuation levels. If the cable terminus is dirty or scratched, the cable terminus can be replaced or repaired. An indicator can be used to disclose to the user exactly which cable terminus is being inspected.

Abstract: An electronic fiberoptic power measuring instrument which utilizes a plurality of different detectors to ascertain the power of a light beam. The light beam that enters the instrument can be selectively altered to be directly transmitted to a primary detector or can be reflected to be transmitted to a secondary detector. The structure for altering the light beam takes the form of a movable member which is arranged to intersect the path of the light beam. The movable member can be moved to a plurality of different positions with a different meter function being obtained at each position.

Abstract: The present invention provides a fiber optic test probe comprising a ferrule having a longitudinal axis and a fixable position and being transversely displaceable, and a gimbal coupled to the ferrule and being transversely displaceable, the gimbal comprising means for constraining transverse displacement of the ferrule from a fixed position.
