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 reversible polarity fiber optic connector includes an outer housing including a polarity key for coupling the outer housing to a fiber optic receptacle in only one orientation. A ferrule assembly is received in the outer housing in a first position corresponding to a first polarity of the fiber optic connector and in a second position corresponding to a second polarity of the fiber optic connector. The ferrule assembly forms an optical connection with the fiber optic receptacle. A boot assembly is releasably connected to the outer housing to enable the ferrule assembly to be inserted into and removed from the outer housing. The boot assembly includes a rotor rotatable between locked and release positions. The rotor includes a blocking portion to block disconnection of the boot assembly with the outer housing in the locked position and to permit disconnection of the boot assembly with the outer housing in the release position.

Abstract: A fiber optic connector has a housing including separately formed housing portions configured to be connected to each other to cooperatively define an enclosure. A first of the housing portions has a latch formed integrally with the first housing portion. A fiber optic ferrule is located in the enclosure of the housing. The housing portions each define a back post element which together define a back post of the housing configured for securing a cable to the 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.

Abstract: The fiber optic adapter may include a main body having a first end portion and a second end portion spaced apart along a length direction, the first end portion having at least a first port configured for receiving at least one ferrule, the second end portion having at least a second port configured for receiving a fiber optic connector; and a sleeve holder provided within the main body and between the first end portion and second end portion such that the first port is in communication with the second port to establish an optical connection. The first port has holding elements to define a receiving space to receive the ferrule, and the receiving space is configured to be expanded when inserting the at least one ferrule into the first port. The fiber optic adapter may receive a ferrule without the need of an outer housing or a spring.
