Product Description

Fiber Optic Test Equipment Fiber Optic Dector VFL to Detect Damage


General information


Visual fault locator use 650nm laser module as emitter, which is suitable for single mode or multimode fiber inspection. The output mode can be chosen between CW and 2Hz frequency of light, it is widely used in optical communication, optical components measurement, fiber optical sensor and other fields.


FOC COMMUNICATION CO., LTD built the Visual Fault Locator to last. Visual Fault Locator incorporates an energy-absorbing holster over an impact-resistant case to withstand drops, impacts and rough treatment, ensuring years of trouble-free operation. Together with a heavy-duty tethered end cap to protect the fiber adapter, Visiual Fault Locator is the VFL for demanding field applications. Unlike more fragile VFL's that utilize a flashlight body or plain plastic case, FOC COMMUNICATION CO., LTD industrially engineered the VisiFault custom-case to be mechanically tough. The case is compact for field-use and ergonomically designed for comfort.
