Visual Fault Locator (VFL) Laser Pen

This product is a Visual Fault Locator, often referred to as a fiber optic laser pen or VFL. It is a handheld tool used by network technicians to identify breaks, bends, and faulty connectors in fiber optic cables. These devices work by emitting a visible red light that leaks out of the cable at points of damage.

While this specific unit does not feature a prominent retail brand name on its housing, this particular design is a generic 'white-label' model mass-produced by numerous manufacturers in China. Brands like Komshine, FiberShack, and various generic sellers on platforms like Amazon and AliExpress market this exact chassis. It is primarily manufactured in electronic industrial hubs in China, such as Shenzhen, and sold globally under various distributor names.
