  • Patent number: 11938519
    Abstract: An optical connector cleaning tool includes: a tool body; and an extension that moves relatively with respect to the tool body. The extension extends out of the tool body and includes a head that presses a cleaning element formed with a tape-like adhesive element onto an optical connector. A relative movement of the extension with respect to the tool body carries the cleaning element to the head, and after carrying the cleaning element to the head, enables the cleaning element to contact the optical connector.
