visual fault locator
A Visual Fault Locator (VFL) is a compact and portable tool used in fiber optic network maintenance and troubleshooting. It is designed to visually locate and identify faults or breaks in fiber optic cables. VFLs are particularly useful in situations where you need to quickly pinpoint issues in a fiber optic cable, such as in data centers, telecommunications networks, or during fiber optic installation and maintenance.
Visual Fault Locators are valuable tools in the world of fiber optics, offering a quick and efficient way to identify issues and ensure the smooth operation of fiber optic networks.
Function: The primary function of a Visual Fault Locator is to emit a visible laser light (typically red) into the fiber optic cable. This light travels along the fiber and is visible through the fiber's protective jacket.
Fault Location: VFLs are used to identify various types of faults, including breaks, bends, and even macro-bends in the fiber. They are especially effective at finding faults in areas where optical power loss may not be detectable by other means.
Laser Type: Most VFLs use a Class 2 or Class 3R laser diode, which emits a visible red light with a wavelength of around 650-660 nm. This red light is easy to see, even in well-lit environments.
Power Output: VFLs typically have adjustable power outputs, allowing the user to vary the intensity of the light depending on the application. The power output is usually measured in milliwatts (mW) and can range from a few mW up to 30 mW or more.
Connector Types: VFLs come with various connector options to match the type of connectors commonly used in fiber optic systems. Common connector types include SC, LC, ST, and others.
