What red light pen is used to locate fiber optic cables in the computer room

The visual fault locator is a commonly used optical fiber detection tool for troubleshooting network faults. A VFL is used to detect faults, breaks, or bends in fiber optic cables by emitting a bright red light that is visible even through the fiber's jacket. It emits a stable red light driven by a constant current source, which is coupled into the optical fiber through an interface. The Optical Fiber Visual Fault Locator (Red Light Pen) utilizes a 650nm semiconductor laser, offering a reliable and stable red light output for fiber fault detection in both single-mode and multimode fibers.
