A cleaning tool includes a head, a take-up reel, a driven roller, and a passthrough component. The head presses a cleaning element, having a tape shape, onto an optical connector. The take-up reel reels the cleaning element retrieved from the head. The driven roller guides the cleaning element on a convey path from the head to the take-up reel. The pass-through component includes a slit through which the cleaning element is extended, and the pass-through component is located between the driven rollers and the take-up reel.

To provide a cleaner configured so that the cleaner can accurately remove dust and dirt, will leave less adhesive residue, and can sufficiently clean areas including an end surface of a ferrule and a guide pin. A cleaner is provided with an adhesive layer having an exposed surface facing an end surface of a connector from which a guide pin protrudes, the adhesive layer being elastically deformable when subjected to contact with the guide pin, and a holding part having a holding wall for holding the adhesive layer while exposing at least the exposed surface, the holding part being capable of bringing the guide pin into contact with the adhesive layer at a position at which the distance from the guide pin to the holding wall is greater than the length of the guide pin.

A cleaning tool includes: a tool main body; an insertion part that moves in a predetermined direction relative to the tool main body, and is configured to hold a head unit movable backward and configured to press a cleaning body against a cleaning target; a retrieve mechanism that retrieves the cleaning body using a relative movement in the predetermined direction between the tool main body and the insertion part; and a rotation mechanism that rotates the head unit after the retrieve mechanism retrieves the cleaning body using the relative movement in the predetermined direction between the tool main body and the insertion part.

An apparatus includes a plurality of connector track elements, each extending substantially perpendicularly from a coupling plane, wherein a particular connector track element of the plurality of connector track elements includes a distribution of at least two magnets adjacent unattached end thereof, a polarity of the magnets on the particular connector track element being selected to provide magnetic repulsion as to at least one adjacent connector track element.

A tensioning spool apparatus for storage of optical fiber exhibiting reduced variation of tension during a retraction cycle versus an extension cycle of fiber over a predefined range of spool rotation cycles, the optical fiber dynamically extended under tension from the spool.

An optical connector cleaning tool includes a cleaning tool main body, a feed-side bobbin, a cleaning head (cleaning portion), a winding-side bobbin, a moving body that moves at the time of cleaning, a feed mechanism that sends an unused cleaning medium in synchronism with the moving body, and a winding mechanism that drives the winding-side bobbin. The feed mechanism moves a turn-back portion at one point where the cleaning medium is turned back in a direction to separate from the winding-side bobbin. The winding mechanism includes a driving piece that engages with a rotation body of the winding-side bobbin. The driving piece slips with respect to the rotation body when a load to press engaging projections of the rotation body has reached a predetermined load.

A ferrule includes an optical transmission member holding part configured to hold an optical transmission member; a first surface that faces an end portion of the optical transmission member when the optical transmission member is held at the optical transmission member holding part; and a through hole that is open between the optical transmission member holding part and the first surface.

A dustcap comprises a body having a cylindrical portion configured to receive a ferrule of an optical fiber connector, and an end portion opposite the cylindrical portion. The end portion includes a receptacle. The dustcap has a built-in cleaner disposed within the receptacle. The dustcap further comprises a removable cover configured to couple to the end portion of the dustcap. In another embodiment, the end portion includes a flat surface, the cleaner is disposed on the flat surface of the end portion, and the cover is configured to receive the end portion of the dustcap. In another embodiment, the cover has a receptacle and the cleaner is disposed within the receptacle, whereas the body comprises an end portion configured to receive at least a portion of the cover with the built-in cleaner. Embodiments encompass cleaner assemblies and adapter dustcaps having built-in cleaners.

A spray nozzle, systems and methods for cleaning at least one optical fiber end face of an optical fiber connector. The nozzle includes a housing body with a first end portion and a second end portion. A discharge passage carries an atomized mixture of cleaning fluid and positively pressurized air from the first end portion to a discharge opening at the second end portion. A vacuum return passage communicates with the discharge passage proximate the second end portion. The return passage receives the atomized mixture of cleaning fluid and positively pressurized air as well as contaminants removed from the optical fiber end face. A portion of the atomized mixture of cleaning fluid and positively pressurized air is diverted from the discharge passage to control the amount of the atomized mixture being directed at the optical fiber end face.

An optical connector cleaning tool includes a cleaning portion (101), a container (102) configured to store a cleaning liquid (121), and an atomizer (103) configured to atomize the cleaning liquid (121) stored in the container (102) by ultrasonic atomization. The atomizer (103) includes an atomizing separation portion (105) configured to cover a liquid supply port (104) and pass not a liquid but mist. In addition, the cleaning tool includes a control circuit (107) configured to control an operation time of the atomizer (103) by a set time.
