Provided is a connector including: an electric transmitter; an optical transmitter including a lens at an end of an optical transmission path; a housing that is allowed to contain the optical transmitter; and a slide mechanism that attaches the lens to a connected unit at a position exposed from a front surface of the housing.

An apparatus for an attenuation adjustment tool, the attenuation adjustment tool includes a body with an adjustment arm positioned at a first side of the body, where an actuator is configured to extend and retract the adjustment arm. The attenuation adjustment tool further includes an input port and an output port positioned at the first side of the body, wherein an input prong and an output prong of a wrap plug are each respectively insertable into the input port and the output port. The attenuation adjustment tool further includes the adjustment arm configurable to engage with a mechanism on the wrap plug, wherein the mechanism is configurable to alter a shape of a signal cable in the wrap plug.

Ferrule for an optical connector, an optical connector containing such a ferrule, and a method for assembling such a ferrule. The ferrule includes a base, at least one cover, at least one fiber section running through a channel between the base and the cover from a cable connection side to an opposite contact face exposing distal ends of the fiber sections. The fibers are adhered to the base and/or to the cover at a bonding section at a distance from the contact face.

A fiber optic connector includes polymeric material arranged within a front end portion of at least one internal bore of a ferrule. At least a portion of the polymeric material extends from a terminal end of at least one optical fiber to at least a front end of the ferrule. A polymeric material end face serving as a conduit for transmitting optical signals to and/or from the at least one optical fiber. Waveguiding regions may be incorporated in polymeric material assemblies. Polymeric material may be printed, dispensed, or otherwise applied over the terminal end of the at least one optical fiber in the at least one internal bore, and subsequently cured. Polymeric material arranged over (e.g., in contact with) the terminal end of an optical fiber may reduce or eliminate the need for fiber end face polishing, and creates physical contact through an optical interface without exerting undue mechanical stresses on the optical fiber.

Provided is an abrasive film not likely to cause an end face defect of an optical fiber connector due to variation in load conditions during polishing, while providing a great grinding force. The abrasive film comprises a substrate film and an abrasive layer overlaid thereon, the abrasive layer comprising abrasive particles and a binder therefor and a wear quantity of the abrasive layer being from 10 mg to 25 mg. A content of the abrasive particles in the abrasive layer is preferably no less than 85% by mass. The abrasive particles preferably comprise first abrasive particles (primary particle diameter: of no less than 10 nm and less than 50 nm), and second abrasive particles (primary particle diameter: no less than 50 nm and less than 250 nm). An average thickness of the abrasive layer is preferably from 4 μm to 15 μm. The abrasive particles are preferably silica particles.

According to an aspect of the invention, an optical receptacle, comprising: a fiber stub including a ferrule containing an optical fiber conducting light; a holder holding the fiber stub; and a sleeve, one end of the sleeve being capable of holding a tip of the fiber stub, one other end of the sleeve being capable of holding a plug ferrule inserted into the optical receptacle, the ferrule including a foreign matter movement suppressor in an end surface of the ferrule, the end surface being polished into a convex spherical configuration on a side to be connected to the plug ferrule, the foreign matter movement suppressor suppressing movement of foreign matter moving, due to inserting and removing the plug ferrule, from an outer circumferential portion of the ferrule toward a central portion of the end surface. It is possible to prevent the loss occurring due to the foreign matter at the outer circumferential portion of the fiber stub moving to the central portion of the end surface of the ferrule when repeatedly inserting and removing the plug ferrule into and from the optical receptacle; and it is possible to reduce the Wiggle loss by maintaining the length where the sleeve holds the fiber stub.

The present disclosure relates to a connector device for optical fiber configured to allow the transmission of an optical signal at a terminal end of the fiber in a cabling condition. The device comprises a portion of optical fiber having a ferrule at at least one terminal end, a ferrule holder element and a protective element for the optical fiber. The overall configuration is such that the connector device has small radial and longitudinal dimensions which, in an operating condition, allow rapid movement within wiring cables or tubular ducts, for example cable ducts, pipes, conduits etc., which due to their sizes, hinder the passage of standard connectors of known type.

An optical connector assembly a first structure and a second structure, the two structures secured together using a retention structure to form a hybrid assembly. The retention structure uses a slot apex located in a slot channel for securing at least one latch pin of a coupling nut to an adapter housing forming the ingress protected connector without the use of a bias spring. The hybrid assembly is designed to resist water or debris ingress, and may eliminate the use of a bias force to further resist separating the hybrid assembly.

One or more cables are axially, laterally, and/or rotationally secured to an anchor member. A plug connector can be assembled to or around the anchor member. The anchor member also can be used to handle the cable prior to assembling the plug connector. A connectorization system for assembling plug connectors includes multiple types/sizes of cables; optionally types/sizes of plug bodies; and the anchor member sized and shaped to connect a selected one of any of the cables with any of the plug bodies of the connectorization system.

The present disclosure relates to lensed optical fiber connector ferrule end faces having molded contact surfaces. The contact surfaces reduce ferrule end face contact area and thereby reduce the influence of trapped dust and debris on lens angular misalignment.
