A device for cleaning an end face of an optical fiber may apply a vacuum to a solvent tank, where the device includes a vacuum generator to apply the vacuum and the solvent tank. The device may receive, from a solvent reservoir and in response to applying the vacuum, solvent with the solvent tank. Additionally, or alternatively, a device for cleaning an end face of an optical fiber may apply a pressure to a solvent reservoir, where the device includes a pressure port to apply the pressure and a solvent tank. The device may receive, from the solvent reservoir and in response to applying the pressure, solvent with the solvent tank.

A device for cleaning an end face of an optical fiber may receive a first pressure signal from a first pressure sensor, wherein the device includes a pneumatic circuit, wherein the pneumatic circuit includes: one or more circuit components, the first pressure sensor, and a second pressure sensor. The device may receive a second pressure signal from the second pressure sensor. The device may determine, based on the first pressure signal and the second pressure signal, whether a pressure difference across a circuit component, of the one or more circuit components, satisfies a threshold. The device may perform, based on the pressure difference across the circuit component not satisfying the threshold, one or more actions.

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.

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 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.

Disclosed herein are devices and methods for cleaning, verifying cleaning, and coating a ferrule end face in a single housing thereby preventing contamination of the ferrule end face and associated optical fiber end face. Also disclosed herein is a fiber optic assembly including a ferrule; an optical fiber extending through the ferrule to an end face of the ferrule; and a coating on the end face of the ferrule protecting the optical fiber. The coating is prepared by curing a vinyl-terminated polydimethylsiloxane with a crosslinker in the presence of a catalyst.

A cleaning nozzle includes an inner nozzle housing having a feed passage for carrying cleaning fluid, a plurality of nozzle tips that each define a discharge opening in fluid communication with the feed passage, and an outer nozzle housing received over the inner nozzle housing. The outer nozzle housing includes a plurality of outer nozzle extensions that each extend over one of the nozzle tips. The outer nozzle extensions can be inserted into ports of an adapter, and flow of the cleaning fluid through the nozzle is split between the nozzle tips so that multiple optical connectors that populate the adapter can be cleaned simultaneously in a substantially uniform manner.

An object is to provide an optical connector cleaning tool capable of cleaning both an end face and a side face of a ferrule of an optical connector plug simultaneously and simply and a method of cleaning an optical connector in such a manner. An optical connector cleaning tool according to the present invention includes superimposing a plurality of cleaning sheets on each other, the cleaning sheets each including a plurality of cleaning strings arranged so as to be parallel to each other in a sheet shape, such that orientations of the cleaning strings included in the respective cleaning sheets differ from each other, pressing an end face of a ferrule of an optical connector plug against the cleaning sheets to clean the end face of the ferrule, and subsequently, sticking the ferrule through the cleaning sheets to clean a side face of the ferrule.

Various implementations of fiber optic inspection tools with integrated cleaning mechanisms are disclosed. The fiber optic inspection and cleaning tool includes a housing, a cleaning system and an imaging system. The cleaning system includes a pay-off reel, a take-up reel, a spindle and a cleaning tape that travels off the pay-off reel, around the spindle, and onto the take-up reel. The imaging system includes a camera and a light source. The camera, spindle, and cleaning tape are aligned along a visual axis. The pay-off reel, take-up reel, camera and light source are all located within the housing.
