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

Typically, the light emitted by the optical fiber will illuminate the buffer that surrounds the optical fiber. 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. 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. 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.) 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.

Visual Fault Locator? How Does It Work? - FullyInstrumented What is Visual Fault Locator? How Does It Work? -

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)

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

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. 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. The Visual Fault Locator is available in different shapes and sizes. Some may look like a pen, others may be built into an optical time domain reflectometer (OTDR), and some may look like a small test equipment box. Pen-Type Visual Fault Locator

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. 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. 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.

Visual Fault Identifiers (VFI) - Can you tell if your fiber is bad? Visual Fault Identifiers (VFI) - Can you tell if your fiber is

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: See connectors that have damaged fibers inside. A damaged fiber inside a connector causes a red light in the connector. Notice the red glow in the connector ferrule. If the light comes up directly on the other end, it means there is no leakage.Taking FS Pen-Type Visual Fault Locator, 1mW as example, it is small in size and easy to be carried away. See high-loss bends. If you can see the light from the VFL at a bend in a fiber, the bend is too sharp. Visual Fault Locator which can be also called visual fault identifier (VFI), fiber fault locator, fiber fault detector, etc, is a visible laser available in red laser light and designed to inject visible light energy into an optical fiber. It is a cost-effective way to spot defects of fiber glass such as sharp bends, breaks, faulty connectors and other faults which will "leak" red or green light visually. It can also locate the fault of OTDR dead zone and make fiber identification from one end to the other end. No matter for installing new fibers or troubleshooting the existing networks, visual fault identifier is a helpful handy kit. 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.
