Connector assemblies are described herein. For example, a connector assembly including: a housing configured to accept a first ferrule and a second ferrule. The connector assembly may also have a push/pull clip that is configure to depress a protrusion that rotates down a connector device to remove the connector assembly from an adapter. The push/pull clip is integrated with a cable boot assembly that allows a user to apply a distal force to remove or insert the connector assembly into the adapter housing. The push/pull clip is configured for use to release a MPO and LC connector type from an adapter.

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 ferrule connection surface and ends of the recessed fibers.

A multi-fiber push on (MPO) optical connector includes a housing supporting a ferrule body. The ferrule body forms an optical connection with a second MPO optical connector. The ferrule body includes a connection end having a distal end face arranged to face the second MPO optical connector when the ferrule body forms the optical connection with the second MPO optical connector. The connection end of the ferrule body defines a recess extending proximally into the ferrule body from the distal end face. A plurality of optical fibers are received in the ferrule body. Distal ends of the optical fibers are adjacent to a proximal end of the recess such that the distal ends of the optical fibers are spaced apart from the second MPO optical connector when the ferrule body forms an optical connection with the second MPO optical connector. The distal ends of the optical fibers are coated with an anti-reflective material.

A ferrule structure includes: a holding aperture that holds light guide members forming light guides; a recess that is recessed from a connection end surface with respect to a mating ferrule; a first lens array on a base surface that is a bottom surface of the recess; and a first groove that is recessed from the base surface and is on an outer side of the first lens array. The first lens array includes lenses that are aligned with the light guides.

An outdoor rated ingress protected connector assembly is formed by a mating connector and a first connector. A lock ring secures the mating connector and first connector together. An outer collar nut is displaceable to unlock the connector assembly to gain access to the internal components. The mating connector and first connector have a fiber optic connector secured therein, which form a transmission pathway when the connector assembly is formed.

A fiber optic connector having a set of opposing pins set in a recess configured to accept a corresponding spring therein. The springs are placed on either side of the fiber optic cable bundle and secured within pinkeep. The dual or outer springs help prevent rotation of the ferrule assembly during use.

An optical connector is provided which can prevent contamination of a lens body with dust or its scratching without a dust cap when being not mated with a partner optical connector. An optical connector is configured to be mounted on a board and to be mated with a partner optical connector which is connected to a terminal end of an optical fiber. The optical connector includes a housing, an optic transceiver, a lens body and a shield case. The housing includes a tubular section for receiving an optical fiber and a ferrule of a partner optical connector. The lens body is located on one side of the tubular section, wherein a film for closing the tubular section is molded integrally with the tubular section on another side of the tubular section. The film is configured to be broken by inserting the optical fiber and the ferrule into the tubular section.

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.

An optical connection device includes an optical fiber, a first connection member which includes an inlet to which the optical fiber is connected and an outlet, a second connection member which includes an aperture connected to the outlet of the first connection member and to which light from the optical fiber is transmitted through the first connection member, and a first light transmission protection part which protects a tip of the optical fiber in the first connection member.
