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.

Adapter system usable in conjunction with a fiberoptic termination inspection microscope to inspect fiberoptic cable end connectors

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.

Fiber optic probe

A device for determining the presence of light in an optical fiber includes a housing having a light-receiving chamber. An aperture in a wall of the housing accommodates insertion of the fiber into the chamber. A brush-configured, light-blocking curtain is mounted adjacent to the aperture and has a plurality of bristles sized and arranged to allow an optical fiber to pass therebetween. A funnel-shaped light reflector is disposed in the chamber adjacent to the curtain and has a first relatively wide diameter opening at a forward end thereof and tapers to a second, relatively narrow diameter light-exiting opening at an apex thereof. An opto-electronic light detector is disposed adjacent to the narrow diameter opening of the funnel-shaped light reflector. Light emitted by an optical fiber that has been inserted through the bristles of the light-blocking curtain impinges upon the opto-electronic light detector. At the same time, the bristles effectively wrap around the fiber and prevent entry of ambient light into the interior of the chamber and onto the light detector. A signal processing circuit is coupled to the output of the light detector generates an output representative of the presence of light in the fiber in response to the measured amount of optical energy exceeding a prescribed threshold.
