    Product Description

    Fiber Optic Test Equipment Pen Type Visual Fault Locator VFL 5mW


    General information

    Visual fault locator emits a bright beam of red light easily visible from a distance. Connect the VFL to one end of a fiber then locate that fiber at the other end, even if it one of many fibers either in a cable or terminated in a rack. Perform simple end-to-end continuity checks. Verify the proper polarity and orientation of fibers within a multi-fiber connector like the MT-RJ.


    Visual fault locator can quickly illuminate fiber breaks, damaged connectors on patch cords, defective splices in splice trays, and tight fiber bends in and around equipment racks. The choice of a continuous wave output mode for steady fault illumination or a flashing output mode makes for easier fault location.
