Male plug fiber optic connectors having configured for mating with a dissimilar connector are disclosed along with cable assemblies using the same. The fiber optic connector comprises a ferrule, a connector housing, and a nose-piece having a pocket disposed at a front portion. The pocket of the nose-piece is configured for allowing optical mating with a dissimilar connector. In one embodiment, the pocket on the nosepiece of the connector is disposed on a forward portion of the nosepiece. The fiber optic connectors disclosed advantageously allow for optical mating with dissimilar optical connectors with a quick and easy assembly for rugged applications or other optical communication networks.

A housing for an optical fiber connector may include a body portion that may be configured to be received by an optical fiber receptacle and a latching portion that may be configured to extend from the body portion proximate a first end of the body portion. The body portion and the latching portion also may be configured to be slidingly received in an optical fiber receptacle via a first end of the receptacle. The latching portion further may be configured to be urged toward the body portion by the receptacle in response to a predetermined pulling force applied to the housing in a direction away from the first end of the receptacle to de-latch the housing from the receptacle such that the housing is slidingly removed from the receptacle without manually operating the latching portion so as to prevent damage to the connector, the receptacle, and/or a fiber terminated by the connector.

A hardened fiber optic adapter that may include a body portion having a first end portion that is configured to receive a hardened fiber optic connector and a second end portion that may be located opposite to the first end portion, a flexible fiber cable lead portion that may include an optical fiber cable and a protection tube portion that may be configured to surround the optical fiber cable, and an adapter subassembly portion that may be configured to be coupled with a preterminated end of the optical fiber cable at a first end portion of the flexible fiber cable lead. A second end portion of the flexible fiber cable lead portion may be configured to be coupled with a drop terminal such that the adapter is permitted to be moved relative to the drop terminal to a predetermined connection orientation that is configured to allow the adapter to be connected to a hardened fiber optic connector.

The present disclosure relates to a multi-fiber fiber optic connector having features that allows for changeability with respect to gender and polarity. Another aspect relates to a multi-fiber fiber optic connector that can be operated as a true push-pull fiber optic connector.

Fiber optic connectors and junctions between fiber optic connectors include ferrules terminating a plurality of optical fibers, the ferrules having a ferrule keying portion that rotationally aligns and constrains the ferrules with a guide keying portion of an annular guide tube. The ferrules may further aligned and constrained and aligned in a lateral direction with a ferrule sleeve in the junction of connectors. Each of the ferrule sleeve and the guide keying portion individually constrain movement of the ferrules in different dimensions, the guide keying portion rotationally aligning and constraining the ferrules, while allowing freedom of movement in a lateral direction, and the ferrule sleeve aligning and constraining the ferrules in the lateral direction, while allowing rotational freedom of movement.

This application discloses an adapter assembly and an optical communications device, and belongs to the field of connector technologies. The adapter assembly is configured to be installed on a hole of a panel, and the adapter assembly includes: an MT/MPO adapter, where the MT/MPO adapter includes a flange plate, an MT port, and an MPO port, the MT port and the MPO port are respectively located on two sides of the flange plate in a thickness direction, and the MPO port is configured to be connected to an MPO plug; and an MT plug, where the MT plug includes an MT optical fiber and an MT clamp that are connected, and the MT plug is connected to the MT port. The flange plate is made of conductive plastic. This application can shield an electromagnetic wave in the optical communications device.

Optical connection systems, optical cable assemblies, and optical receptacle assemblies for optically coupling multiple optical fibers are disclosed. In one embodiment, an optical receptacle assembly includes a receptacle housing, wherein the receptacle housing defines a receptacle passage, and an adapter sleeve disposed within the receptacle passage of the receptacle housing. The adapter sleeve includes a sleeve passage and a sleeve inner threaded surface. The optical receptacle assembly further includes an adapter housing disposed within the receptacle passage having a first connector opening and a second connector opening, a first receptacle optical connector and a second receptacle optical connector. The first receptacle optical connector is disposed within the first connector opening of the adapter housing and the second receptacle optical connector is disposed within the second connector opening of the adapter housing.

An optical connection system for use with a receptacle and an optical cable assembly includes an adapter and connector. The adapter has an adapter latch element, and the connector has a connector latch element. A delatch actuator with a delatch arm is disposed on the connector housing for movement from a locking position to an unlocking position. One of the adapter latch element and connector latch element is a bendable latch hook and the other is a locking channel. When the connector housing is mated with the adapter, the delatch arm allows the bendable latch hook to latch with the locking channel in the locking position and unlatches the bendable latch hook from the locking channel as it moves to the unlocking position. An actuator lock movably supports a blocking member on the connector for selectively blocking the delatch actuator from moving to the unlocking position.

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.

There is described a fibre optic connector for insertion to a fibre optic adaptor, the fibre optic connector comprising a body portion and a latch mechanism provided on the body. The latch mechanism comprises at least one resiliently deformable latch member and the resiliently deformable latch member comprises at least one engagement element. The at least one engagement element comprises a leading surface and a trailing surface, wherein the angle between said trailing surface and said at least one resiliently deformable latch member is obtuse.
