The laser-powered VisiFault locates fibres, verifies continuity and polarity, and helps find breaks in cables, connectors and splices. In today's fast-paced workplace maximizing productivity is essential. Whether installing new fiber links or troubleshooting an existing network, the faster you can locate a problem, the faster you can fix it. That's easier said than done when you are faced with a complex network of fibers, connectors and patch cords. Clean the split sleeve with an alcohol soaked cleaning swab (FSWB-C). Replace the split sleeve onto fiber ferrule and screw housing into place securely. Typically, students join wires that appear wonderful under a microscope but fail continuity testing. When this happens, the most difficult element is detecting which connector contains the optical fiber break. In the absence of a VFL in the classroom, students would have to cut the cable in half and use a continuity tester to locate the faulty connection. Networks Centre presents the Fluke Networks Visual Fault Locator as part of our Cable Testing and Measurement range.

Once there is a fault, light will leak out from the cladding and the light will not go through the other end of the cable. Visual Fault locator (VFL) is a basic fiber optic for troubleshooting fiber optic link. It is a must-have test gear in every fiber technician’s tool box. Read on to get information if you are:

Product Overview

Use the VFL button to turn on the visual fault locator (see picture below). Or, on the home screen tap TOOLS, then tap Visual Fault Locator (VFL). You can tap the PULSE/OFF/CW (continuous wave) button on the screen to change the modes of the VFL, or use the button as shown in the picture below.

You can diagnose and repair simple fiber link problems with Fluke Networks' VisiFault TM Visual Fault Locator (VFL). The laser-powered VisiFault Visual Fault Locator is a cable continuity tester that locates fibers, verifies cable continuity and polarity. This cable continuity tester helps find breaks in cables, connectors and splices. Continuous and flashing modes make for easier identification. Compatible with 2.5mm and 1.25mm connectors for easy connection. Ruggedly constructed for demanding field-testing. This visual fault locator has a long battery life for hours of use. In the same way, the visual fault locator can be used to assess the continuity of an optical cable. When utilizing a continuity tester, the first step is to clean and visually verify the connector’s end face before inserting it into the continuity tester. After cleaning and inspecting the connector, make sure the continuity tester is working properly. Turn on the continuity tester and make sure it is emitting light. How to Use

Clean ST connector ferrule end face with a lint-free wipe (FWP-C) soaked with alcohol (reagent grade isopropyl alcohol, with a minimum 90% concentration). To see the light that comes out of a connector, hold a white paper in front of the fiber connector. Typically, the light emitted by the optical fiber will illuminate the buffer that surrounds the optical fiber. All visual fault locators can work with both single mode and multimode fibers. Since multimode fiber has a 50um or 62.5um core, which is much bigger than single mode fiber's 9um core, more light power can be coupled in to multimode fibers. That translates to longer fiber distance for multimode fibers than single mode fibers. Modulation frequency (CW and 2Hz) Taking FS Pen-Type Visual Fault Locator, 1mW as example, it is small in size and easy to be carried away.
