Abstract: 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.

Abstract: An optical fiber array with high reliability, which relates to the technical field of optical fibers is disclosed. The optical fiber array is composed of three parts, namely, optical fiber positioning substrate (1), cover plate (2) and optical fiber ribbon (3). One end of the optical fiber ribbon is striped to be a naked fiber (4). The naked fiber (4) is pressed into the micro-groove array of the optical fiber positioning substrate (1) by the cover plate (2) and glued and fixed with a glue layer (5), and a transitional region between the stripped part and the unstripped part of the optical fiber ribbon (3) is glued and fixed onto a rear half of the optical fiber positioning substrate (1) with the glue layer (5). It has a reasonable and novel structural design. Through frosting of the surfaces of the positioning substrate (1) and the cover plate (2) to be bonded with glue, gluing area between the glue layer and the optical fiber positioning substrate, the cover plate and the optical fiber ribbon can be increase and bonding strength of the glue layer can be enhanced so that it can work in harsh environment of high temperature and humidity without de-bonding to ensure positioning accuracy of optical fibers.

Abstract: Optical fiber connectors for MT/MPO type ferrule assemblies are disclosed, having an overall connector length less than about 32 mm, for example, an overall length of about 18.5 mm for non-reinforced optical fiber cables, and an overall length of about 23.5 mm for reinforced optical fiber cables. In one embodiment, a connector comprises a ferrule assembly, and a housing coupled to the ferrule assembly and configured to couple to an adapter corresponding to the ferrule assembly. The connector further includes a lock coupled to the housing and configured to rotate so as to lock and unlock the housing from said adapter. An interface member coupled to the housing may include a stop configured to limit rotation of the lock. The interface member may include a reinforcement portion for reinforcing optical fiber cables.

Abstract: An optical connector holding two or more LC-type optical ferrules is provided. The optical connector includes an outer body, an inner front body accommodating the two or more LC-type optical ferrules, ferrule springs for urging the optical ferrules towards a mating receptacle, and a back body for supporting the ferrule springs. The outer body and the inner front body are configured such that four LC-type optical ferrules are accommodated in a small form-factor pluggable (SFP) transceiver footprint or eight LC-type optical ferrules are accommodated in a quad small form-factor pluggable (QSFP) transceiver footprint. A connector is released by pulling distally on boot assembly until receptacle hook is displaced from receptacle hook recess at a proximal end of connector.

Abstract: Reversible polarity fiber optic connectors are provided having housings at least partially surrounding first and second optical ferrules with walls above and beneath the ferrules. Positioning removable elements such as latches, removable arms, or push-pull tabs on the first wall above the ferrules yields fiber optic connectors with a first polarity type, and positioning the removable elements on the second wall beneath the ferrules yields fiber optic connectors with a second, opposite polarity type. Various engagement mechanisms are provided on either the connector housing walls or on the removable elements, or both, to assist in affixing the removable element to the connector housing.
