Abstract: Provided is an optical connector cleaning tool that is unlikely to cause a static charge and can accurately remove dust located on an end surface of an optical connector. Disclosed is an optical connector cleaning tool including: a main body housing a supply holder configured to hold a cleaner that has a contaminant-retainable layer and can be supplied so as to clean an end surface of an optical connector; a cleaning head configured to position the cleaner having been supplied from the main body and be held at a certain holding position with respect to the main body; a controller that can be engaged with the optical connector and can be displaced from a first position to a second position, which is different from the first position, with respect to the cleaning head while kept engaged with the optical connector; and a supply mechanism configured to transmit, to the cleaner, movement of displacing the controller from the first position to the second position to displace and then supply the cleaner to the cleaning head, in which when the controller is positioned at the first position, the cleaning head is apart from the end surface of the optical connector, while the controller is displaced from the first position to the second position, the supply mechanism causes the cleaner to be displaced, and when the controller is positioned at the second position, the cleaning head comes into contact with the end surface of the optical connector.

Abstract: Provided is an optical-electrical composite cable in which, even if the entire optical-electrical composite cable having an optical fiber routed along flexible flat wiring boards is made thin, the optical fiber is not deformed or damaged by a large bending stress. A pair of the flexible flat wiring boards are disposed on a front surface side and a rear surface side of the optical fiber, and a covering member integrates the entirety thereof. Thus, even if the optical-electrical composite cable is made thin, the cable is not bent with a large curvature without deformation of the optical fiber.
