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.

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.
