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

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: 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. 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. If the end face finish is acceptable, the VFL can be attached to a fiber connector. During this testing, the VFL should not be viewed directly. Taking FS Pen-Type Visual Fault Locator, 1mW as example, it is small in size and easy to be carried away.

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 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. 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. Networks Centre presents the Fluke Networks Visual Fault Locator as part of our Cable Testing and Measurement range.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).

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 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 The laser-powered VisiFault locates fibres, verifies continuity and polarity, and helps find breaks in cables, connectors and splices. Visual fault locator cable continuity tester locates fibers, finds faults, verifies continuity and polarity. 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 modeYou 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.
