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.

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.

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.

An optic fiber adaptor includes two flexible engaging members and two positioning walls cooperating with one another to define an insertion slot. Each engaging member has a first inclined surface and a second inclined surface disposed behind the first inclined surface. A distance between the first inclined surfaces of the engaging members decreases rearwardly so as to facilitate pushing of a casing body of a ferrule assembly into the insertion slot. A distance between the second inclined surfaces of the engaging members decreases forwardly so as to facilitate pulling of the casing body out of the insertion slot. An optic fiber connecting device having the optic fiber adaptor is also disclosed.

An optic fiber connector assembly, including at least one adapter and at least one connector, is provided. The adapter is correspondingly connected to the connector. The adapter includes a first housing, at least one sleeve disposed in the first housing, at least one bridging portion extending out of a side of the first housing, and at least one locking arm extending from the side and located next to the bridging portion. The sleeve extends from an inside of the first housing to the corresponding bridging portion. The connector includes a second housing, a ferrule disposed in the second housing in a penetrating manner, and a spring abutted between the second housing and the ferrule. The second housing is sleeved onto the bridging portion, the ferrule is inserted into the sleeve, and the locking arm is buckled onto the second housing.

A fiber optic cassette includes a body defining a front and an opposite rear. A cable entry location is defined on the body for a cable to enter the cassette, wherein a plurality of optical fibers from the cable extend into the cassette and form terminations at non-conventional connectors adjacent the front of the body. A flexible substrate is positioned between the cable entry location and the non-conventional connectors adjacent the front of the body, the flexible substrate rigidly supporting the plurality of optical fibers. Each of the non-conventional connectors adjacent the front of the body includes a ferrule, a ferrule hub supporting the ferrule, and a split sleeve surrounding the ferrule.

The present invention discloses a fiber optic connector comprises: a ferrule assembly; a spring seat provided behind the ferrule assembly; and a spring provided between the ferrule assembly and the spring seat. The spring seat has a receiving chamber having an insertion port through which a portion of the ferrule assembly is inserted into the receiving chamber; wherein the ferrule assembly is pre-assembled into the receiving chamber of the spring seat in a way that the ferrule assembly is held to be movably engaged with the spring seat. The spring is fitted and compressed in the receiving chamber. As a result, the ferrule assembly, the spring seat and the spring are pre-assembled into an integral assembly before being inserting into a connector housing. All components of the connector except for the housing may be smoothly pulled through a small long pipe as a whole. After being pulled through the pipe, all components of the connector except for the housing may be easily and quickly inserted into the housing as a whole at one time.

The present invention discloses a guide pin, which comprises a base support layer (1) and a protective layer (2). The base support layer (1) is a rod-shaped structure. The protective layer (2) tightly wraps the surface of the base support layer (1). A manufacturing method for the guide pin made of various materials is also disclosed. The guide pin manufactured by the method of the present invention is not prone to bending or deformation and has good corrosion resistance and acid/alkaline resistance properties; it is wear resistant and has of extended service life; it is easy to be processed and is low in cost.

The present disclosure relates to a fiber optic connector for use with a fiber optic adapter. The fiber optic connector includes a connector housing having an end defining a plug portion. A ferrule assembly is mounted at least partially within the connector housing. The ferrule assembly includes a ferrule located at the plug portion of the connector housing. A sealing member is mounted about an exterior of the connector housing for providing a seal between the connector housing and the adapter. The fiber optic connector further includes first and second separate retaining mechanism for retaining the fiber optic connector within the fiber optic adapter.

An optical connector includes a first sub-assembly that is factory-installed to a first end of an optical fiber and a second sub-assembly that is field-installed to the first end of the optical fiber. The optical fiber and first sub-assembly can be routed through a structure (e.g., a building) prior to installation of the second sub-assembly. The second sub-assembly interlocks with the first sub-assembly to inhibit relative axial movement therebetween. Example first sub-assemblies include a ferrule, a hub, and a strain-relief sleeve that mount to an optical fiber. Example second sub-assemblies include a mounting block; and an outer connector housing forming a plug portion.
