About this deal

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) 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.) 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.

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 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. 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 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.

To see the light that comes out of a connector, hold a white paper in front of the fiber 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. 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. 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 and repair simple fibre link problems with Fluke Networks' VisiFault™ Visual Fault Locator (VFL). See connectors that have damaged fibers inside. A damaged fiber inside a connector causes a red light in the connector. Step 2: Connect the fiber visual fault locator to the opti-crimp connector ferrule (with the included patch cord), turn on the VFL.

Visual Defect Locator

Step 1: Clean the fiber optic cable connector endface and attach your visual fault locator to the connector. The laser-powered VisiFault locates fibres, verifies continuity and polarity, and helps find breaks in cables, connectors and splices.
