A ferrule for optical fiber connector includes a first body component, a second body component, and a third body component. The first body component includes at least one first mounting portion and two accommodation portions. The second body component is disposed above the first body component, and includes at least one second mounting portion, where the at least one second mounting portion corresponds to the at least one first mounting portion. The third body component is disposed above the first body component and the second body component, and includes at least one positioning through aperture and two second through apertures, where the two second through apertures correspond to the two accommodation portions, respectively. The first body component, the second body component, and the third body component are adhered integrally together, with adhesive. Also disclosed is a positioning mold for positioning the ferrule. By using the positioning mold, the ferrule for optical fiber connector can be assembled more easily, so as to improve the productivity in manufacturing optical fiber connectors.

A fiber optic connector includes a housing body, a spring push, a connecting plug, a sleeve and a conversion unit. The spring push and the connecting plug are disposed in the housing body. The sleeve is sleeved on the housing body. The conversion unit includes a clamping member and two guide pins. The clamping member is disposed in the housing body, and has two clamping portions. The clamping portions are switchable between a clamping state, in which the guide pins are clamped by the clamping portions and protrude from the connecting plug, and a non-clamping state, in which the guide pins are released from the clamping portions and removed from the connecting plug.

Dust plug assemblies and methods of their fabrication are disclosed. In one embodiment, a dust plug assembly includes a dust plug body having a lanyard receiving feature, and a sealing sleeve attached to an end of the dust plug body. The sealing sleeve has a passageway therethrough, and the lanyard receiving feature is disposed within the passageway. The dust plug body and the sealing sleeve define a primary groove. The dust plug assembly further includes a lanyard having an attachment feature. The attachment feature is coupled to the lanyard receiving feature, and the lanyard and the sealing sleeve define a secondary groove.

Perimeter external surfaces of a 2D arrays of stripped optical fibers are used as datum surfaces for alignment structures for mating connectors in fiber optic cable assemblies. 2D fiber arrays may include involutions and/or protrusions to serve as mating locations for alignment structures and/or to serve as keying structures. A removable sleeve may be positioned around at least a portion of a 2D fiber array to align mating connectors and/or bias alignment structures toward one another. Fiber-free areas may be provided in an interior of a 2D fiber array to receive alignment structures. One or more compliant members may be configured to press first and second alignment structures toward one another proximate to a 2D fiber array. A cable assembly fabrication method includes forming window stripping and adhering optic fiber groups while preventing adhesive material from protruding beyond outermost surfaces of optical fibers at a perimeter of a fiber array. Multiple 2D fiber arrays with peripheral protective structures may be received in a connector sleeve and biased toward one another.
