Optical Fiber Identifiers
GAO Tek’s fiber identifiers are devices used in fiber optic networks to determine the presence and direction of optical signals within an optical fiber. They work by clamping onto the fiber without disrupting the signal flow and using non-destructive methods to identify and locate active fibers. Our fiber identifiers are used in fiber optic installation, maintenance, and troubleshooting to verify the connectivity and integrity of fiber optic cables.

GAO’s fiber identifiers are composed of a clamping mechanism, an optical sensor, display or indicator, power source, control buttons or interfaces, and fiber adapter or receptacle.

The other common names of fiber identifiers are fiber identifying tools, optical fiber identifiers, fiber cable identifiers, fiber line identifiers, optical core identifiers, fiber optic line identifiers, fiber path identifiers, fiber network identifiers, optical cable identifiers, fiber bundle identifiers, optical strand identifiers, fiber thread identifiers, fiber identification devices, cable fiber locators, and fiber signal tracers.
