## Description

VisiFault Visible Light Source - Optical Cable Conduction Tester Optical cable conduction tester with visible light source identifies optical fiber and detects abnormalities and confirm continuity and polarity. Detects fiber failures such as tight bending, breakage, or bad connectors. Promotes end-to-end optical fiber checking Easy polarity checking and fiber optic identification You can choose between continuous and flashing modes. ● Ergonomic case protects against drops, shocks, and vibrations ●Supports 2.5mm and 1.25mm SFF connectors Battery life is more than 80 hours (uses 2 AA batteries) Overview Maximizing your productivity is crucial in today's fast-paced workplace. Quick fault detection is required for fast handling and repairs, such as installing new fiber links or troubleshooting an existing network. However, when you face a network complicated by fiber, connectors, and patch cords, it is easy to say and difficult to do. Fluke Networks VisiFaultTM Visible Light Source allows you to diagnose and repair simple fiber link faults. VisiFault visible light source with laser light source detects fiber optic and confirms the conductivity and polarity of the optical cable. Use this optical cable conduction tester to detect damage to optical cables, connectors and splices. Continuous mode and flash mode make identification easier. Compatible with 2.5mm and 1.25mm connectors, easy to connect. Rigid construction that can withstand test sites and has a long battery life for long use. Features » Fiber Certification and Abnormal Detection VisiFault emits a bright red laser light that can be seen from a distance. Connect a VisiFault visible light source to one end of the fiber optic to identify the distant end whether it is inside an optical cable or in many optic cables terminated on a rack. Performs simple end-to-end conduction tests. You can also check the proper polarity and orientation of the fiber optic in the multi-fiber connector such as MT-RJ. VisiFault quickly locates broken fiber optics, damaged connectors on optical patch cords, bad splices on splice trays, and tight bends of fiber optic within and around the equipment rack. You can easily detect abnormalities by selecting a continuous wave output mode or flash output mode to ensure detection of obstacles. » Easy Operation Universal 2.5mm adapter makes it easy to connect SC, ST, FC and FJ connectors. Optional 1.25mm adapter is available for connecting LC to MU connectors. Use a lanyard or hang it on a belt for easy handling. Over 80 hours of battery life (2 AA batteries) in continuous mode. » Durable Construction The VisiFault from Fluke Networks is designed to last. The VisiFault incorporates a shock-absorbing holster built into a shock-absorbing case that is durable against drops, shocks, and rough handling, ensuring long-term trouble free operation. VisiFault has a durable end cap with cord to protect fiber adapters, making it a VFL that can handle the toughest job sites. Unlike the fragile VFL that uses a flashlight body or a simple plastic case, the Fluke Networks Industrial Engineering VisiFault case is designed to be mechanical and tough. Ergonomically designed, easy-to-use case is compact and suitable for the field

## Questions & Answers

**Q: i see other testers around less then $100 that do +25mW from the product page it states <1.3 mW output power, is this accurate?**
A: The output power level listed on the device is < 1.3 mW; wavelength 630-670 nm; class II laser product.  I will tell you that the device works very well across great distances.  The light source is very strong so it may be a combination of power level and wavelength that make it work well.  Also we use a lot of Fluke devices and find them to be very reliable although a bit more expensive.

**Q: How far will this device test. can i test a 15km  or 20 km length of fiber with it**
A: Thank you for your question. The Visifault has a range of 3 km on Multimode fiber and 4 km on Singlemode fiber.

**Q: What is the Wavelength this Fault Locator**
A: Diego,  the output of this device is <1.3 mw and the wavelength is 630-670 nm.  It is a class II laser product.   This information taken off the label on the unit itself.

**Q: What is the warranty?**
A: Check on Flukes website.I will say these things are absolutely indispensable. We use them daily to set up very large area (Railroad) fiber networks around the worldThey are very rugged, and we have never had a problem.They have been of sufficient value and reliability that even if there was no warranty, I wouldn't hesitate to purchase them.
