The invention also relates to an adapter sleeve (26).

A fiber optic connector and cable assembly includes a cable with one or more strength members secured to a connector that is connectable to both a hardened and a non-hardened fiber optic adapter. The cable can include multiple cable types with various shapes and strength member configurations. The connector includes a connector housing having a one-piece main body and a cover piece mounted thereon. The one-piece main body defines a plug portion compatible with the adapters. A ferrule assembly is mounted in the plug portion and biased outwardly by a spring. An insert within the connector housing includes a spring stop for holding the spring and a cable retention portion for securing the strength members of the cable. The spring stop and the cable retention portion can be included on a one-piece insert or they can separately be included on separate inserts. The cable retention portion of the insert and the cover piece can take various forms suited for a particular cable of a given fiber optic connector and cable assembly.

A ferrule mold having a reverse-image of a through-hole array for optical fibers is formed. A non-polymeric ferrule material is deposited in the reverse-image mold, followed by removing the mold to create a multi-fiber connector ferrule having at least two fiber through-holes. An optical fiber is inserted in each through-hole until each fiber endface is positioned approximately even with a connection surface of the ferrule. A fiber recess for each of the optical fibers is formed such that each fiber is recessed from the multi-fiber ferrule connection surface by a distance of at least 0.1 micron. The recess may be formed by differential polishing of the non-polymeric ferrule and endfaces of the optical fibers. Alternatively, a layer of spacer material may be deposited over the multi-fiber ferrule connection surface. An antireflection coating is deposited over the ends of the recessed fibers.

An optical connector assembly (OCA) includes a connector housing to maintain alignment between optical components housed within the OCA and photoelectric converters on an optoelectronic substrate (OES) assembly. The optical components include a ferrule and an optical cable. The ferrule is optically coupled to the optical cable. The OCA includes a ferrule holder to hold the ferrule within the OCA, and a spring located between the connector housing and the ferrule holder. The spring is to apply a separating force between the ferrule holder and the connector housing. The OCA includes a gasket coupled to the connector housing. The coupling of the connector housing to a socket compresses the gasket to provide a seal between the connector housing and the socket.

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.

A fiber optic ferrule includes a body extending from a first end to a second opposite end, with the body including an axial passage extending between the first and second ends. The axial passage includes a first diameter portion having a diameter of at least 125 microns, and a second diameter portion having a diameter of at least 250 microns and less than a diameter of the buffer, the second diameter portion positioned between the first diameter and the second end. The axial passage further defines a tapered shape at the second end extending inward from the second end to the second diameter portion. A hub holds the ferrule. A method of assembling a terminated fiber optic cable is also provided.
