Methods of reshaping ferrules (20) used in optical fiber cables assemblies (170) are disclosed. The reshaping methods reduce a core-to-ferrule concentricity error (E), which improves coupling efficiency and optical transmission. The methods include measuring a distance (δ) and angular direction (θ) from a true center (30) of the ferrule to the core (46), wherein the true center (30) is based on an outer surface (26) of the ferrule. The methods also include reshaping at least a portion (26P) of the ferrule (20) to define a new true center (30′) of the ferrule (20) and reduce the distance (δ). A variety of reshaping techniques are also disclosed.

A fiber optic connector having a ferrule extending along a longitudinal axis and a ferrule holder from which the ferrule extends. The fiber optic connector also includes a housing having a housing body in which the ferrule holder is received and a housing cap configured to be attached to the housing body. The housing cap defines a front end of the housing when attached to the housing body. The ferrule holder and housing body allow rotation of the ferrule holder relative to the housing body about the longitudinal axis when the housing cap is not attached to the housing body. The housing cap restricts rotation of the ferrule holder relative to the housing body about the longitudinal axis when the housing cap is attached to the housing body.

A fiber optic connector (20) including a ferrule (42) having a front end (48) and a rear end (50). The ferrule (42) defines an axial bore (46) that extends through the ferrule (42) between the front end (48) and the rear end (50). The ferrule (42) includes a ferrule axis (64) that extends along the axial bore (46). The fiber optic connector (20) includes an optical fiber (62) positioned within the axial bore (46) that is movable relative to the ferrule (42) within the axial bore (46) along the ferrule axis (64). The optical fiber (62) has fiber end face (63) that has been energy treated to round the fiber end face (63). A fiber alignment structure (66) can be attached at a front ferrule end face (54) of the ferrule (42). A camera can be used to position a fiber end face (63) of the optical fiber (62) relative to the front ferrule end face (54) of the ferrule (42).

The present invention discloses a fiber optic connector comprising a housing, a spring, a ferrule assembly and a crimping seat. Before being inserted into the housing, the ferrule assembly is pre-assembled into the crimping seat in a manner of being movable relative to the crimping seat. The spring is pre-assembled into the housing before the ferrule assembly is inserted into the housing. After the pre-assembled ferrule assembly and crimping seat are inserted into the housing, the crimping seat is snap-fitted in the housing, and the spring pushes the ferrule assembly, so that the ferrule assembly is capable of being moved against the spring relative to the crimping seat. Before inserted into a housing of the fiber optic connector, some components may be pre-assembled together to form an integral assembly having a size less than that of a housing of the fiber optic connector. Accordingly, the integral assembly may be smoothly pulled through a small long pipe. After pulled through the pipe, the integral assembly may be easily and quickly inserted into the housing as a whole at one time.

Devices and methods for connecting optical fibers are provided. In some embodiments, connectors and adaptors containing mechanical-transfer type of ferrule are disclosed. In some embodiments, the mechanical-transfer type of ferrule is a mechanical-transfer dual-ferrule.

In some embodiments, an optical fiber cable that couples with at an optical fiber connector, adaptor, and other optical fiber cable using a remote release is disclosed.

A connector assembly (1) including a first connector unit (2) and a second connector unit (3) interconnectable with respect to each other. The first connector unit (2) includes at least one connector (5) arranged at least partially inside a plug housing (4). The at least one connector (5) is operatively connected to the plug housing (4) by a latching mechanism (7) which provides an engaged configuration in which the at least one connector (5) is latched with respect to the plug housing (4) and a disengaged configuration in which the at least one connector (5) is disengaged from the plug housing (4).

Devices and methods for connecting optical fibers are provided. In some embodiments, connectors and adaptors for two-fiber mechanical transfer type ferrules are disclosed. In some embodiments, MT connectors, such as simplex, duplex, and quad micro-MT adaptors are disclosed. In some embodiments, MT adaptors, such as simplex, duplex, and quad adaptors are disclosed. In some embodiments, optical fiber cables that modularly coupled with at least one optical fiber connector, adaptor, and other optical fiber cable the cable is configured to provide a remote release from an adaptor receptacle.

The present disclosure relates to an optical fiber alignment device that has an alignment housing that includes first and second ends. The alignment housing defines a fiber insertion axis that extends through the alignment housing between the first and second ends. The alignment housing includes a fiber alignment region at an intermediate location between the first and second ends. First and second fiber alignment rods are positioned within the alignment housing. The first and second fiber alignment rods cooperate to define a fiber alignment groove that extends along the fiber insertion axis. The first and second fiber alignment rods each having rounded ends positioned at the first and second ends of the alignment housing.

An optical fiber connector includes a main body unit having a guiding groove, and two position limiting portions that respectively protrude from two walls respectively defining two sides of the guiding groove toward each other, a sleeve unit, and a coupling unit including two coupling members each having two first protruding block portions that respectively protrude away from each other. The sleeve unit is configured to be movable rearwardly on the main body unit to press the first protruding block portions toward each other, so as to allow the first protruding block portions to pass past the position limiting portions, thereby allowing for movement of each of the coupling members between a non-working position and a working position.

Fiber optic connectors comprising multiple footprints along with 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.
