**Visual Fault Locator (Fiber Optics)**
In the United States, VFL usually refers to Visual Fault Locator, which is a test instrument used in fiber optic communication to identify breaks, bends, or other problems in fiber optic cables.
A VFL is a simple and inexpensive tool that can be used to quickly identify problems in fiber optic cables. It is a handheld device that emits a visible laser light source. The light is injected into one end of the fiber optic cable, and if there is a break or other problem in the cable, the light will leak out and can be seen with the naked eye.
VFLs are typically used for troubleshooting fiber optic cables in the field. They are not as accurate as other fiber optic test instruments, but they are a quick and easy way to identify problems.
