Visual Fault Locator (VFL), Red Light Pen 10mW Fiber Optic Cable Tester Meter with 2.5mm Connector for Fiber Fault Finding, Up to 10KM

Product Information

To see the light that comes out of a connector, hold a white paper in front of the fiber connector. A visual fault identifier or visual fault locator (VFI / VFL) is a visible red laser designed to inject visible light energy into a fiber. Sharp bends, breaks, faulty connectors and other faults will “leak” red light allowing technicians to visually spot the defects. You can diagnose and repair simple fibre link problems with Fluke Networks' VisiFault™ Visual Fault Locator (VFL). It will help you to easily discover optical fiber breakage or macro bends, as well as a bad fusion splice in multimode or single-mode optical fiber. You can diagnose fiber link problems over fiber optic cables or fiber cable pigtails using visual fault locators. When the fiber fault locator is designed with adapter incompatible with your connector type, using additional adapters is necessary.

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. 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: 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. Taking FS Pen-Type Visual Fault Locator, 1mW as example, it is small in size and easy to be carried away. See connectors that have damaged fibers inside. A damaged fiber inside a connector causes a red light in the connector.The fiber distance spec tells the longest fiber length where you can still see the leakage light without difficulty. This spec is determined by the laser light power. The industry standard spec is 10km for multimode fibers and 5km for single mode fibers. FS high power 30mW fiber optic fault locator enables up to 15km dynamic distance. Output power Clean and inspect the fiber optic cable connector with a microscope. If the endface finish is acceptable, the VFL can be connected to a fiber connector. See high-loss bends. If you can see the light from the VFL at a bend in a fiber, the bend is too sharp.

The VFL directs laser light into the core of the optical fiber. The laser’s light exits the optical fiber at a break or macro bend. 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. 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.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. Visual fault locator cable continuity tester locates fibers, finds faults, verifies continuity and polarity. Human eyes are much more sensitive to blinking light than to a steady light. So visual fault locators provides two operating modes: continuous wave and pulse light. In most cases, fiber optic installation technicians prefer the pulse light mode which turns the laser source on and off in 2Hz or 1Hz frequency. Battery The VFL enables the operator to view the optical fiber break. The optical fiber may break in places other than fiber optic cables. Inside the connector or connector ferrule, the optical fiber may break. A microscope cannot see the optical fiber unless it is damaged at the end face of the connection. Notice the red glow in the connector ferrule. If the light comes up directly on the other end, it means there is no leakage.The Visual Fault Locator (VFL), like the continuity tester, is an essential instrument in any fiber optic tool kit. The VFL is not one of the cheapest instruments in your toolbox. Function Increase the quality of mechanical splices and prepolished connectors: Before you seal the splice or connector, adjust the fiber alignment for the minimum amount of light where the fibers touch. (Refer to the instructions from the manufacturer when you make splices and connectors.) 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. Output power is an important spec for visual fault identifiers. Some may ask how many power do I need? The key is: The higher output power is, the longer fiber distance it can support. This spec is usually 0.5mW coupled to single mode fibers and 2mW to free space (which means no fiber coupling, just the light output from the tester's connector adapter). Fiber mode Step 1: Clean the fiber optic cable connector endface and attach your visual fault locator to the connector.
