Fiber optic connectors, cable assemblies and methods for making the same are disclosed. In one embodiment, the optical connector comprises a housing and a multifiber ferrule. The housing comprises a longitudinal passageway between a rear end and a front end, and a rear portion of the housing comprises a keying portion and at least one locking feature integrally formed in the rear portion of the housing.

A factory processed and assembled optical fiber arrangement is configured to pass through tight, tortuous spaces when routed to a demarcation point. A connector housing attaches to the optical fiber arrangement at the demarcation point (or after leaving the tight, tortuous spaces) to form a connectorized end of the optical fiber. A fiber tip is protected before leaving the factory until connection is desired.

The present disclosure relates to a plasma treatment (under atmospheric conditions or under vacuum conditions) of a jacketed cable comprising a cable jacket and a heat shrink tubing. The plasma treatment improves retention properties of an optical fiber cable assembly by imparting a permanent change on a polymer surface of the cable jacket by cross-linking, leading to eventual graphitization, that can result in a diffusion barrier layer at an interface of the cable jacket and the heat shrink tubing, which prevents or minimizes plasticizer migration and results in an environmental seal (e.g., a long-term water tight seal).

Fiber optic connectors, cable assemblies and methods for making the same are disclosed. In one embodiment, the optical connector comprises a housing and a ferrule. The housing comprises a longitudinal passageway between a rear end and a front end, and, a part of the rear portion of the housing comprises a round cross-section and a part of the front portion of the housing comprises a non-round cross-section with a transition region disposed between the rear portion and the front portion.

A front housing of the optical-electrical composite connector is axially provided with a through groove passing through the front housing on the front housing, and an inner wall of the through groove is provided with a first groove. A rear housing includes a main body portion and a clamping portion connected to one end of the main body portion. An outer surface of the clamping portion is axially provided with a second groove, the clamping portion is located in the through groove, and the first groove is butted with the second groove to form an accommodation space. One end that is of the through groove and that is away from the main body portion is an optical port. The font housing is provided with an opening connecting to the accommodation space and the outside. The conductive terminal is accommodated in the opening, and the conductive terminal forms an electrical port.

Embodiments of the disclosure relate to an optical fiber cable having at least one optical fiber, a cable jacket and a foam layer. The cable jacket includes an inner surface and an outer surface in which the outer surface is an outermost surface of the optical fiber cable. The inner surface is disposed around the at least one optical fiber. The foam layer is disposed between the at least one optical fiber and the cable jacket. The foam layer is made of an extruded product of at least one thermoplastic elastomer (TPE), a chemical foaming agent, and a crosslinking agent. The foam layer has a closed-cell morphology having pores with an average effective circle diameter of less than 100 μm. Further, the foam layer has a compression modulus of less than 1 MPa when measured at 50% strain.

An optical fiber connector can terminate a plurality of optical fiber cables, each with a jacket encasing at least one optical fiber and a strength element. A connector housing has a back post. The optical fibers of the plurality of optical fiber cables extend into the connector housing through the back post. A single crimp ring crimps the strength members of the plurality of optical fiber cables onto the back post. In a method of terminating a plurality of optical fiber cables, the cables are inserted through a single crimp ring, optical fibers of each of the cables are terminated in a multifiber ferrule, the cables are loaded into a back body of a connector housing, and strength members of the cables are crimped onto a back post using a single crimp ring.

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 invention discloses a type of optical fibre connector, comprising: an external shell; an internal shell, installed within said external shell; an inserted core component, contained within said internal shell and comprising an inserted core and a length of optical fibre pre-installed within said inserted core; and a spring, contained within said internal shell and located behind said inserted core, and being for exerting a pre-set axial force on said inserted core. Said internal shell includes a front part and a rear part; said rear part is assembled on said front part. Additionally, said spring is compressed between said rear part and said inserted core. In the present invention, the rear part can act as a retainer for the compressed spring and can also be for securing the Kevlar fibre extension tube of the optical cable. As a result, in comparison to the prior art, the present invention reduces the number of components of the optical fibre connector and simplifies the structure of the optical fibre connector, thus facilitating rapid on-site assembly of the optical fibre connector.

A fiber optic connector is disclosed that includes a plug body having a plug end and a connector core that mounts within the plug body. The connector core includes a ferrule subassembly including a ferrule, a ferrule hub that attaches to the ferrule, a spring holder and a connector spring. The ferrule sub-assembly is assembled with the connector spring pre-compressed to an initial compressed state prior to mounting the connector core within the connector body. The plug body and the core are configured such that the connector spring is moved from the initial compressed state to a final compressed state when the connector core is loaded in the plug body. In certain examples, tuning features can be integrated into the connector core.
