Various implementations of visual inspector attachments for fiber connector cleaners are disclosed. The example fiber optic inspection module includes a camera to capture an image of an end-face, a light source to illuminate the end-face, and a first mirror that reflects light from the light source to the end-face and includes a fixed point that allows the first mirror to pivot. Alternatively, an example fiber optic inspection module includes a camera to capture an image of an end-face, a light source to illuminate the end-face, and a first mirror that reflects light from the light source to the end-face and the first mirror moves in an upward direction.

A cleaning tool includes: a head; and a cleaning body wrapped around the head. The head includes: a head body; and a projection that projects from the head body. The projection is retractable relative to the head body. The head may further include an elastic member that restores a positional relationship between the projection and the head body.

The nozzle includes a nozzle body having a front end with a recess defining a recessed wall. The recess is elongate in a first direction. The recess receives a front-end section of a ferrule of a multi-fiber connector to define gap, wherein the front-end section has an elongate end face. The nozzle has first and second channels that are elongate in the first direction and have respective first and second front-end openings at the recessed wall. The first and second front-end openings are spaced apart in a second direction perpendicular to the first direction. A cleaning fluid flows from the first channel into the gap and then out the second channel, including over the ferrule end faces and end faces of optical fibers supported by the ferrule. A flow-disrupting feature on the recessed wall generates turbulent flow to enhance cleaning.

An apparatus for treating optical fibers can be used to carry out necessary cleaning work on the end tips of the glass fibers of fiber-optic cables. The apparatus has modules which are provided with non-abrasive surface layers able to pick up contaminants and are spring-mounted in relation to one another such that they can be pivoted about a hinge joint, and, in the case of at least one of the modules, elastic material layers are introduced between the surface layer and the main body of the assembly. The assemblies are preferably designed in the form of grip plates, between which non-abrasive, cloth-like layers are applied, as a cleaning surface, to each of the facing surfaces and, in the case of both gripping plates, elastic insulating materials are arranged between the cloth-like surface layer and the gripping plate.

Provided is a cleaning device that can follow a complicated shape and can accurately remove stains by using a resin having high toughness.

A cleaning device including a contaminant collector, in which the cleaning device is characterized in that the contaminant collector includes a polyurethane resin, the contaminant collector has an Asker C hardness of 45 to 90, and the contaminant collector has a tensile strength of 2.0 MPa or more and 30 MPa or less.

An attachment cleaning tool includes: a cleaning tool; and an attachment detachably attached to the cleaning tool. The cleaning tool includes: cleaning bodies that clean connection end surfaces of ferrules of an optical connector; head members each that press the cleaning bodies against the connection end surfaces; nozzle members that respectively accommodate the head members; a feeding mechanism that supplies and withdraws the cleaning bodies with respect to the head members; and an accommodating body which accommodates the feeding mechanism. Each of the connection members of the attachment includes: an attachment portion attached to a tip portion of each of the nozzle members; and a tubular portion that protrudes from the attachment portion in a longitudinal direction of the nozzle members and into which one of the ferrules is inserted. The connection members move following a relative movement of the nozzle members in the lateral direction.

An optical connector cleaning tool includes a fitting portion (44) fitted in the first or second hole (36, 37) of a connection component (32) into which a compact dual core optical connector is fitted on one end side and a cleaning medium (45) projecting from the fitting portion (44). The fitting portion (44) is formed to have a shape by which the fitting portion (44) is fitted in the first or second hole (36, 37) in each of the first and second postures as postures shifted through 180° with respect to as the center the middle (P2) of a virtual straight line connecting the centers of the two ferrules when viewed from an axial direction of the compact dual core optical connector. The fitting portion (44) contacts one ferrule in a state in which the fitting portion (44) is set in the first posture. The fitting portion (44) contacts the other ferrule in a state in which the fitting portion (44) is set in the second posture. There can be provided an optical connector cleaning tool by which the connection end faces of the compact dual core optical connector having two ferrules in one housing can be cleaned.

A cleaning body 10 of the present invention includes a cloth-like body unit 11 and a washing liquid enclosure 12 provided on a surface of the body unit 11 or inside the body unit 11 and enclosing a washing liquid including alcohol. This can reduce a burden of conveyance by a user to enhance safety, and suitably exhibit cleaning capability.

An attachment cleaning tool includes: a cleaning tool; and an attachment detachably attached to the cleaning tool. The cleaning tool includes: cleaning bodies that clean connection end surfaces of ferrules of an optical connector; head members each that press the cleaning bodies against the connection end surfaces; nozzle members that respectively accommodate the head members; a feeding mechanism that supplies and withdraws the cleaning bodies with respect to the head members; and an accommodating body which accommodates the feeding mechanism. Each of the connection members of the attachment includes: an attachment portion attached to a tip portion of each of the nozzle members; and a tubular portion that protrudes from the attachment portion in a longitudinal direction of the nozzle members and into which one of the ferrules is inserted. The connection members move following a relative movement of the nozzle members in the lateral direction.

A cleaning nozzle includes an outer housing having a central axis and an inner surface that defines an outer housing interior. An inner housing resides within the outer housing interior along the central axis and has an inner surface that defines an inner flow channel. The inner flow channel supports flow of the cleaning fluid and has a converging taper and a flow disrupter element. The nozzle assembly may include an adapter that receives a front end of the nozzle and that also holds a ferrule that supports an optical fiber having an end face. The nozzle assembly allows the nozzle to direct a jet stream of cleaning fluid to the ferrule end face and the fiber end face. The flow disrupter causes the jet stream to have a time-varying direction that enhances the cleaning of the ferrule end face and the optical fiber end face.
