The Pen Type Visual Fault Locator is a compact, portable device for troubleshooting fiber optic networks. It is also known as a Visual Fault Finder or VFF. The purpose of the Visual Fault Locator is to visually locate breaks, bends, or other faults in fiber optic cables.

1. Adopting pen type design, compact and lightweight, easy to carry.
2.Support multiple interfaces to meet different needs.
3. Simple operation, easy to identify fiber breaks and bends
4.Adopt high brightness laser light source to ensure that the fault point is clearly visible even at long fiber distance.

It is widely used in a variety of fiber optic applications, including telecommunication networks, data centers, and the installation and maintenance of fiber optic cables. It is a convenient tool that helps technicians quickly identify and locate faults for efficient troubleshooting and repair of fiber optic connections.
The Pen Type Visual Fault Locator Pen Type is designed to emit bright visible laser light into fiber optic cables, typically in the red wavelength range (e.g. 650nm). When the laser encounters a fault, such as a break or bend, it scatters or leaks from the fiber, producing a visible red light at the fault location. This makes it easier for technicians to identify and locate problem areas in fiber optic links.
