A hybrid ingress protection adapter and connector assembly, connecting the housing with a releasably replaceable connector and power assembly to an adapter that is mount on a panel. The connector has a pair of lead-ins that protect a ferrule of a plural of fiber optic connectors, and the lead-ins are of varying length allow blind mating of the connector assembly with the adapter assembly.

Reversible optical connectors, and associated devices and methods are provided. In one embodiment, a connector for a communication cable includes a housing comprising a cavity, and a first plug and a second plug coupled to a distal portion of the housing. The first and second plugs are connected to the housing such that the first and second plugs are independently rotatable with respect to the housing. The connector further includes a latch actuator coupled to the housing and configured to disengage one or more latches from an outlet. By rotating the plugs 180 degrees and turning the connector over, the relative arrangement or position of the two plugs can be switched or reversed. The plugs can be rotated or reversed without completely disassembling the connector, in some embodiments. Accordingly, embodiments of the present disclosure can improve workflows for a user or operator that in a high-density networking setting.

A fiber optic adapter assembly reduced in size from a SFP footprint to a SC footprint to accommodate a first fiber optic connector on a first side within one or more ports, and a second fiber optic connector on a second side within one or more ports. The first fiber optic connector is a duplex fiber optic connector with an overall length of about 50 mm and the second fiber optic connector is a behind-the-wall connector with an overall length of about 15 mm thereby reducing the overall length of a connector and adapter assembly for increasing optical fiber density.

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 tool for a plug to which a cable having its basal end covered with a boot is attached is disclosed. The plug includes a plug body fitted to an adapter and a slider supported on the plug body. The tool includes an insertion portion that catches the slider, and a boot surrounding part that has a sleeve-like shape and accepts insertion of the cable and the boot, to accommodate the boot while the insertion portion is catching the slider. The boot surrounding part includes a slit extending along an entire length in an axial direction of the boot surrounding part and having a width greater than a diameter of the cable and smaller than a maximum diameter of the boot. While the insertion portion is catching the slider, the boot surrounding part is positioned inner than an outermost shape line of the plug as seen in the axial direction.

A cover for a fiber optic ferrule and ferrule push includes a sleeve extending lengthwise between opposed front and rear ends and defines a lengthwise-extending opening that opens through the rear end for receiving at least a portion of the fiber optic fiber optic ferrule and the ferrule push. The sleeve also includes a top side and an opposing bottom side, and two side walls extending between the top side and the bottom side and along at least a portion of the sleeve. A receiver is disposed in the top side to receive a projection associated with the ferrule push.

A fiber optic connector includes a ferrule, an insert body, a tail sleeve and two core heads. The ferrule includes an outer frame, and an operating handle extending rearwardly from the outer frame. The outer frame is formed with an inserted opening open along a front-rear direction and two limiting slots open along a left-right direction and spaced apart from each other along the left-right direction. The insert body is detachably inserted into the ferrule and includes two protrusion units protruding away from each other along the left-right direction and respectively movable in the limiting slots.

A ferrule pin clamp used for a ferrule into which a guide pin is inserted includes: a main body including a pin holder that holds a groove portion of the guide pin. The pin holder includes a pair of arcs. A diameter of the pair of arcs: is smaller than a maximum shaft diameter of the guide pin, and is larger than a shaft diameter of the groove portion of the guide pin.

A connector member fixes an optical fiber. The connector member includes an optical fiber; a clamping member that clamps the optical fiber; and a friction imparting member that is interposed between the optical fiber and the clamping member.

There is provided herein a solution for measuring the optical power loss of duplex optical-fiber devices under test, and particularly those terminated with a duplex connector interface, which allows for a one-cord or one-cord equivalent testing method whichever the format of the duplex connector interface of the optical-fiber device under test, and this without disconnecting the optical fibers of the device under test from their duplex native connector interface. There is provided an optical-fiber expansion device to be used to interconnect and adapt a power meter instrument to a variety of duplex connectors. The proposed optical-fiber expansion device comprises a pair of optical fibers having a core diameter and a numerical aperture that are greater than those of the optical fiber in the DUT connector interface, so as to make it compatible with the one-cord testing method. Interchangeable optical-fiber expansion devices can be used to match the power meter interface on one side, to various duplex connector interfaces under test on the other side.
