FVFL-204 Pen Shape Visual Fault Locator is a compact but powerful fiber optical cable test tool, with an output power up to 1mW, which can be used to locate sharp bends & breaks in jacket or bare fiber within 5km. It can also be applied to identify the connectors in patch panels and identify the fibers during splicing operation. The choice of a continuous wave output mode for steady fault illumination or a flashing output mode makes for easier fault location.
