Extralink Fiber checker pen VFL fault locator, 5km range, 1mW

Fiber Fault Checker is a small and lightweight device that emits a visible red laser. It can be used to check single and multi-mode optical fibers very effectively. Connected to the fiber optic cable via fiber optic connector. The red laser can be used as a reference point and to locate the point where the fiber optic cable has failed, which the OTDR cannot find (fiber optic cable break; start and end) and the area of high bending loss.<br> <br>It is ideal for passive fiber network elements patchcord, pigtail, fiber core box or bare fiber cable. These products are widely used in optical communication, optical transmission, optical fiber, fiber detection and other fields of scientific research, production and construction. Checker can test not only single mode fiber, but also multi-mode fiber.Extralink Fiber checker pen VFL fault locator, 5km range, 1mW
