A hand-held inspection probe is a portable device used in fiber optic network installations and maintenance. It is designed to visually inspect the quality and cleanliness of fiber optic connectors, ensuring optimal performance.

The inspection probe typically consists of an optical microscope or a digital camera mounted on a handheld. It allows technicians to examine the end-face of a fiber optic connector or a patch cord to detect any dirt, scratches, or other defects that may interfere with signal transmission.

The inspection probe provides magnification and illumination to clearly view the connector end-face. It may have various interchangeable tips adapters to accommodate different connector types such as LC, SC, ST, or MPO.
