Visual fault locators are used to identify problems with your fiber. GAOTek visual fault locators typically are applied for fiber tracing, fiber routine, and continuity checking. Imagine being able to easily identify when and where a fiber is breaking, bending, or when there’s a threat to the fiber layer.

Support an optimized fiber network, using a visual fault locator. Every day, our visual fault locators are used by technicians in-the-field and in rugged environments in the United States, Canada, and globally. A visual fault locator is a cost-effective way to get it done with complete mechanical connecting point detection and optimization.

Test your next fiber run using any of our visual fault locators. They work flawlessly to deliver accurate information even in low light and with a long battery life. The lightweight design also makes it easy to carry and not any trouble to throw in with any existing tools or equipment you have.

Without a visual fault locator, identifying pinched fibers, breakpoints, poor connections, bending, and bad splices are a guessing game and impossible to confirm. With a GAOTek visual fault locator, you have a level of certainty you can work from. In service to your fiber optic network, you’ll be pleased to have one to grab when you need it.

How a visual fault locator works is simple. Using a red laser, visible light is injected into an optical fiber. Then, when the red light shows through at a break, a technician can instantly spot the problem. For inexperienced technicians or anyone looking for some extra confirmation, a technician may choose to darken the area to better identify the damaged region of the fiber jacket.

GAOTek visual fault locators boast a strong performance, are highly accurate, and improve productivity at every turn. Regardless of the test conditions, you can rely on our visual fault locators to give you precise information. Low-cost, handheld visual fault locators come with a range of features and are competitively priced.
