The fiber optic end face cleaning pen can facilitate the timely cleaning of the fiber optic end face by the installer during installation, preventing small dust, oil or water stains from contaminating the fiber optic end face and ensuring the overall transmission performance of the fiber optic link.

The fiber optic detection pen allows the construction company to conduct initial testing on the fiber optic link as soon as it is installed, identify those fiber optic links with breakage points or poor connection points, and promptly rectify them, preparing for further performance tests such as fiber optic link attenuation.
