A fiber optic cable connector configured to be securely coupled with a cable jacket without crimping includes a connector body including a rear sleeve portion configured to receive a jacket of a fiber optic cable, a ferrule holder configured to be slidingly seated in a forward end of the connector body, a ferrule configured to be seated in the ferrule holder and to terminate an optical fiber, and a retention member having an inner diameter sized to fit into an annular groove in the jacket of the fiber optic cable and an outer diameter sized to extend radially outward of an outer surface of the jacket such that the retention member is configured to engage a surface of the rear sleeve portion of the connector body when the retention member is seated in the annular groove in the jacket so as to increase connection strength between the connector body and the jacket and to resist pull force on the fiber optic cable without crimping the connector body to the jacket.

The present disclosure relates to using a coating to protect a portion of an optical fiber that is intended to buckle within a fiber optic connector. The fiber optic connector can include a bare fiber optical connector.

Fiber optic connectors and junctions between fiber optic connectors include ferrules terminating a plurality of optical fibers, the ferrules having a ferrule keying portion that rotationally aligns and constrains the ferrules with a guide keying portion of an annular guide tube. The ferrules may further aligned and constrained and aligned in a lateral direction with a ferrule sleeve in the junction of connectors. Each of the ferrule sleeve and the guide keying portion individually constrain movement of the ferrules in different dimensions, the guide keying portion rotationally aligning and constraining the ferrules, while allowing freedom of movement in a lateral direction, and the ferrule sleeve aligning and constraining the ferrules in the lateral direction, while allowing rotational freedom of movement.

An optical ferrule has a different thermal expansion coefficient than a substrate to which a optical device is mounted, the ferrule optically coupling the device to one or more optical fibers. The optical ferrule includes and/or a cradle in which the ferrule is mounted include lateral and longitudinal engagement feature that ensure alignment with the optical device at an operating temperature, the ferrule expanding relative to the substrate when transitioning to the operating temperature.

A multi-fiber push-on/pull-off (MPO) connector and an MPO connector tool configured to facilitate insertion and removal into and from an MPO adapter. The MPO connector includes a ferrule, an inner housing holding the ferrule, an outer housing slidably coupled to the inner housing, and a clip coupled to one end of the outer housing and including a main body, a pair of longitudinally extending latch arms for engaging the outer housing, and a pair of laterally extending posts extending from the main body. In use, the MPO connector tool is positionable to apply a force on the laterally extending posts to translate the clip thereby translating the outer housing longitudinally to facilitate connector insertion and removal.

An optical fiber connecting component includes a glass plate having a plurality of first through holes, a resin ferrule fixed to the glass plate and having a plurality of second through holes that are each coaxial with corresponding one of the plurality of first through holes, and a plurality of optical fibers including a glass fiber and a resin coating that covers the glass fiber. The glass fiber exposed from a tip of each of the optical fibers is held in corresponding one of the first through holes and corresponding one of the second through holes, and a material for the resin ferrule has a flexural modulus of 5 GPa or more at 200° C.

This application discloses an adapter assembly and an optical communications device, and belongs to the field of connector technologies. The adapter assembly is configured to be installed on a hole of a panel, and the adapter assembly includes: an MT/MPO adapter, where the MT/MPO adapter includes a flange plate, an MT port, and an MPO port, the MT port and the MPO port are respectively located on two sides of the flange plate in a thickness direction, and the MPO port is configured to be connected to an MPO plug; and an MT plug, where the MT plug includes an MT optical fiber and an MT clamp that are connected, and the MT plug is connected to the MT port. The flange plate is made of conductive plastic. This application can shield an electromagnetic wave in the optical communications device.

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.

A process for terminating an optical fiber with a ferrule includes the steps of: (a) providing an optical fiber and ferrule with an end of the optical fiber extending beyond a surface of the ferrule; and (b) directing a jet comprising an air-abrasive mixture at the end of the optical fiber to cleave the end of the optical fiber from the remainder of the optical fiber.

The present disclosure relates generally to methods for processing ferrules of fiber optic connectors such that the amount of cleaving and/or polishing that is required is eliminated or at least reduced. An apparatus and method of dispensing adhesive through a front end face of a fiber optic ferrule are provided.
