Product Details
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.
Applications
- Maintenance in telecom, CATV
