A pre-terminated end of a fiber optic cable has a protective cap that protects the optical fiber and the ferrule assembly at the terminal end. The protective cap has an attachment feature enabling a pull cord to attach to the protective cap. The protective cap has a body including an exterior surface and a receptacle formed in the body and configured to receive a portion of the fiber optic cable, and the attachment feature. The attachment feature includes a cavity formed in a tip of the body and at least two openings formed in the exterior surface of the body and connected to the cavity.

A dust plug for a fiber optic connector includes a plug wall, an alignment member and a ferrule protector. The plug wall includes a first side and a second side. The plug wall may or may not be part of a housing. The alignment member may extend from the first side of the plug wall wherein the alignment member is configured to engage with and be disposed within an adapter. The ferrule protector may extend from the second side of the plug wall wherein the ferrule protector may be configured to receive a ferrule of a fiber optic cable. The ferrule protector, the plug wall, and the alignment member may be configured to block a signal from the ferrule when the ferrule is disposed within the ferrule protector and when the member is inserted into the adapter.

The present disclosure relates to a fiber optic connection system (810) that uses a slide clip to provide robust retention of a fiber optic connector (820) within a mating fiber optic adapter (836). In certain examples, the fiber optic connector may be a hybrid connector that provides both electrical and optical connectivity.

A fiber connector plug includes a main housing sleeved over a periphery of a fiber and a first locking structure disposed on an outer surface of the main housing, where the first locking structure is used to fit a second locking structure on a fiber adapter, the first locking structure includes a sliding member and a locking part, the locking part is fastened to the main housing, and the sliding member is slidably connected between a first position and a second position to the main housing; the locking part is located between the sliding member and a ferrule; and when the sliding member is located in the first position, the sliding member fits the locking part to jointly lock the second locking structure.

Multiports having connection ports with securing features that cooperate with flexures and methods for making the same are disclosed. In one embodiment, a multiport comprises a shell, at least one connection port, at least one flexure and at least one securing feature. The at least one connection port comprises an optical connector opening and a connection port passageway, and the at least one flexure is associated with the at least one connection port. The at least one securing feature is associated with the at least one connection port, where the at least one securing feature cooperates with the at least one flexure.

A protection assembly of an optical fiber socket is disclosed. The optical fiber socket includes a first lock portion. The protection assembly includes a protection member and an unlock member. The protection member includes a hollow body inserted in the optical fiber socket and an elastic fastening structure. The hollow body has an unlock hole. The elastic fastening structure includes an unlock portion and a second lock portion for locking in the first lock portion. The unlock member includes a rod and a pushing protrusion provided at one end of the rod. When the second lock portion is locked in the first lock portion, the rod is adapted to be located inside the hollow body via the unlock hole, the pushing protrusion is adapted to push against the unlock portion along with a rotation of the rod.

An example fiber control collar is provided. The fiber control collar includes a body, an opening, and a protrusion. The body includes a front surface and an opposing rear surface. The opening is formed in and extends through the body from the front surface to the rear surface. The protrusion extends from the front surface. The fiber control collar is configured to be positioned within a complementary hollow section of a connector backshell component to maintain fibers of a fiber optic cable away from pinch points during assembly of the fiber optic connector.

An apparatus including a first ferrule, a second ferrule and a tracing fiber. The first ferrule may comprise a cap. The second ferrule may comprise the cap. The tracing fiber may be configured to propagate light from the first ferrule to the second ferrule. The first ferrule may enable the light to be directed into the tracing fiber when the cap is removed. The cap of the second ferrule may be configured to scatter the light to provide an omnidirectional emission of the light from the second ferrule. The tracing fiber may be bundled with one or more data carrying lines in a cable. Each of the data carrying lines may be configured to enable a communication of data. The tracing fiber may be configured to propagate the light without interrupting the communication of data.

Provided is an adapter. The adapter includes a housing and an elastic component. The elastic component is configured to connect the housing with an installation frame. The elastic component includes an installation body, a blocking portion and a clamping elastic piece, the blocking portion and the clamping elastic piece are disposed on the installation body. The installation body is configured to be detachably connected to the housing. A first clamping gap capable of accommodating the installation frame is provided between the blocking portion and the clamping elastic piece.

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.
