Abstract: A light source unit generates an optical signal out of a bend-insensitive (“BI”) optical fiber that is compliant with a desired encircled flux (“EF”). The unit includes a light source to generate an optical light signal and a conventional multimode optical fiber coupled to receive the optical light signal from the light source at a first end. A modal conditioner is arranged to condition the optical light signal propagating along different modes of the conventional multimode fiber. A first bend-insensitive (BI) multimode optical fiber has an input end, the input end of the first BI multimode optical fiber being coupled at a second end of the conventional multimode optical fiber to receive the conditioned optical light signal from the conventional multimode fiber. The output from the first BI multimode optical fiber outputs an optical signal having the desired EF.

Abstract: The system determines whether an orientation of a ferrule was changed between measurements made to the end face geometry of the ferrule. Accordingly, the systems allows confirmation that a ferrule was re-oriented between measurements before calculating any deviations in the measurement tool and applying corrective algorithms. An indication (e.g., alarm, error message, etc.) may be conveyed to the user to properly re-orient the ferrule.

Abstract: A fiber optic ferrule inspection tool (100) inspects and cleans a fiber optic ferrule (900). The tool includes a mounting arrangement (216), a camera (500), a grazing light assembly (800), an axial light (512), and a nozzle (320, 320′). The mounting arrangement (216) is adapted to releasably mount the fiber optic ferrule. The camera (500) is mounted to the mounting arrangement and captures at least one image (920, 922) of the fiber optic ferrule. The grazing light assembly (800) is mounted to the mounting arrangement and is adapted to emit grazing light and thereby illuminate an end (902) of the fiber optic ferrule. Rays (rg) of the grazing light are oriented to the end of the fiber optic ferrule within an angular range of 0 to 30 degrees. Rays (ra) of the axial light (512) are oriented to the end of the fiber optic ferrule about an angular range within 30 to 90 degrees. The nozzle (320, 320′) is positioned by the mounting arrangement and is adapted to supply ionized air (352) and thereby clean and electrostatically neutralize the fiber optic ferrule.

Abstract: An inspection tool for allowing visual inspection of an end face of a fiber optic ferrule. The inspection tool includes a passage for allowing a camera to view the end face. The inspection tool also includes light directing structure for first directing ferrule illumination light axially along the inspection tool, and then reflecting the axial light across the end face of the fiber optic ferrule.
