A multiple push-on (MPO) optical connector is provided having a ferrule configured to house multiple optical fibers and a housing having a distal end in a connection direction configured to hold the ferrule. The housing further includes a pair of proximal apertures and at least one proximal groove. A backpost has a distal end that urges the ferrule toward the distal end of the housing and a proximal end configured to receive a crimp ring. The backpost includes a pair of proximally extending latch arms that reverse latch in the proximal apertures of the housing. To strengthen the connector in side-loading environments, the backpost further includes a reinforcing rib that is received in the housing proximal groove. In a further aspect, the proximal end of the backpost may include a neck with an approximately curved side profile that, following crimping with a stepped crimp ring, results in an angled crimp.

An epoxy-free, high-durability and low-cost plastic optical fiber splice design and fabrication process which meets commercial airplane environmental requirements. The splice design: (1) does not require the use of epoxy to join the end faces of two plastic optical fibers together; (2) incorporates double-crimp rings to provide highly durable pull force for the plastic optical fibers that are joined together; (3) resolves any vibration problem at the plastic optical fiber end faces using a miniature stop inside a splice alignment sleeve; and (4) incorporates a splice alignment sleeve that can be mass produced using precision molding or three-dimensional printing processes.

An optical fiber connector allowing more precise connection, having a front casing and an insertion core assembly; the front casing has an installation hole where the insertion core assembly is installed: the insertion core assembly has an insertion core and a tail rod; the tail rod has a tail rod head portion and a tail rod necking portion: the tail rod head portion fixedly sleeves one end of the insertion core; the tail rod head portion has a quadrilateral cross section; a cross section of the installation hole also has a quadrilateral shape that matches the quadrilateral cross section of the tail rod head portion.

This invention reveals a type of optical fiber connector assembly, comprising of a shell, an optical fiber adapter, an optical fiber connector and optical cable. The optical cable is provided with an optical cable securing device, an optical cable strengthening component being secured to the optical cable securing device, and the optical fiber within the optical cable passes through the optical cable securing device. The optical fiber connector assembly also comprises a first port end cap; the optical cable securing device is separate from the optical fiber connector, and fits within the accommodating cavity therein; the outer end of the end cap possesses an arrestor wall, which prevents the optical cable securing device from being pulled out of the accommodating cavity within the end cap; additionally there is a compressed spring provided between the end cap and the optical fiber adapter, the compressed spring being squeezed between the end surface of the end cap and the end surface of the optical fiber adapter. In this invention, since there is only a compressed spring provided on one side of the optical fiber adapter, the compressed spring being squeezed between the end cap and the end surface of the optical fiber adapter, the overall axial and radial size of the optical fiber connector assembly is reduced.

A fiber optic ferrule receiver includes a main body that has an opening extending between the front end and the rear end and being defined at least by a portion of internal surfaces of the four sides. A first side in the opening has first tapered surface and a second tapered surface, the first tapered surface reducing the opening between the rear end and a first position and the second tapered surface increasing the opening between the first position and the front end. There is also a second side in the opening and across the opening from the first side, the second side has a third tapered surface and a fourth tapered surface, the third tapered surface reducing the opening between the rear end and a second position and the second tapered surface increasing the opening between the second position and the front end. There is also a first projection extending into the opening from the first side to engage a first portion of the fiber optic ferrule at the first position, and a second projection extending into the opening from second side to engage a second portion of the fiber optic ferrule at the second position.

A fiber optical connector assembly with a crimp tube assembly improves tensile load on the optical fiber cable or microduct jacket when the connector assembly is used as part of an optical network that is secured between towers spaced apart 1,000 meters or more. The crimp tube assembly has one or more crimp zones, and the crimp tube assembly has a lip formed on an inner surface of the crimp right assembly to improve tensile strength when the crimp tube assembly is secured to a back post of a first fiber optic connector assembly that is air blown or push through a duct or conduit. An epoxy resin may be injected into a cavity between the cable jacket and the crimp tube assembly to improve tensile load strength.

A new fiber optic connector provides a smaller form factor by including two ferrule assemblies in a housing. The housing accepts a push-pull mechanism that allows for insertion and removal from a carrier as well as an adapter. The push-pull mechanism may also include a flexure member to return the push-pull mechanism. Polarity of the fiber optic connector may also be selected by use of the push-pull mechanism.

A fiber optic cable assembly or termination system is preconnectorized and may include different combinations of collars, crimp bands, and clamp assemblies to improve functionality of the arrangement.
