Using a Visual Fault Locator (VFL)

Today, we'll talk about tools for checking fiber optic cables. One important tool is the fault locator, also called a visual fault locator or VFL. It has a red light that goes through the cable. If the light doesn't come out the other side, there might be a problem. A broken cable lets light escape through the jacket instead of going through the fibers. You can also use the VFL to check the bend radius, which is how tight the cable bends. Too tight, and the light escapes, making it dim. If it's really tight or broken, the light escapes a lot. So, a VFL helps find breaks and check if light goes from one end to the other. If there's still an issue, you might need to clean or use an OTDR for more tests. Hope this tip helps!
