A female hardened fiber optic connector for terminating an end of a fiber optic cable that is suitable for making an optical connection with another hardened cable assembly and cable assemblies using the same are disclosed. The female hardened fiber optic connector includes a connector assembly, a crimp body, a connector sleeve, and female coupling housing. The connector sleeve has one or more orientation features that cooperate with one or more orientation features inside the female coupling housing. The crimp body has a first shell and a second shell for securing the connector assembly at a front end of the shells and a cable attachment region rearward of the front end for securing a cable.

Female hardened optical connectors for use with male plug connectors

A fiber optic connector includes a ferrule having a mating end and an insertion end and a ferrule holder having a first end portion in which the ferrule is received and a second end portion opposite the first end portion. The first end portion defines a first bore having a first bore width for receiving the ferrule. Additionally, the first end portion defines a bore surface and at least one groove formed in the bore surface. The at least one groove extends from where the insertion end of the ferrule is located within the first bore to a front face of the ferrule holder. Ridges are formed around the first bore because the at least one groove also extends in a circumferential direction. The ridges contact the ferrule and are deflected by the ferrule in a direction toward the insertion end of the ferrule.

Fiber optic connector with vented ferrule holder

A female hardened fiber optic connector for terminating an end of a fiber optic cable that is suitable for making an optical connection with another hardened cable assembly and cable assemblies using the same are disclosed. The female hardened fiber optic connector includes a connector assembly, a crimp body, and a shroud. The crimp body has a first shell and a second shell for securing the connector assembly at a front end of the shells and a cable attachment region rearward of the front end for securing a cable. The crimp body fits within the shroud and is secured within the shroud using a locking feature disposed on a rim area of the shroud. The female hardened connector may further include a receptacle having a non-hardened receptacle port and a hardened receptacle port, where alignment fingers of the female hardened connector fit into distinct openings on the non-hardened receptacle port side.

Female hardened optical connectors for use with hybrid receptacle

A fiber optic assembly includes a connector and a cover received over an end face of the connector. The connector includes a ferrule through which an optical fiber extends to the end face of the connector. An end of the optical fiber is polished proximate to the end face. The cover the cover includes a rigid end cap and a form-fitting material within the end cap overlaying the polished end of the optical fiber. The cover is configured to limit access of particulates to the end face of the connector and draw loose particulates of dust and debris from the end face of the connector upon removal from the connector.

Fiber optic connector cover and fiber optic assembly including same

A fiber optic assembly includes a connector and a cover bonded to an end face of the connector. The connector includes a ferrule, where an optical fiber extends through the ferrule and to the end face of the connector. An end of the optical fiber is polished proximate to the end face. The cover is bonded directly to the end face of the connector, and overlays the polished end of the optical fiber such that the cover protects the optical fiber, limits access of dust to the end face of the connector, and draws loose particulates from the end face upon removal of the cover.
