There is provided an optical assembly (100) comprising an optical fiber arrangement (220, 230) and a lens arrangement (120). The lens arrangement (120) is spatially disposed relative to the fiber arrangement (220, 230) so as to be capable of providing an axial substantially collimated beam of radiation in response to receiving radiation from the optical fiber arrangement (220, 230) and capable of providing a focused beam of radiation to the optical fiber arrangement (220, 330) in response to receiving substantially collimated radiation to the lens arrangement (120). The assembly (100) further comprises a configuration of elements (110, 130, 200, 260) for spatially disposing the optical fiber arrangement (220, 230) relative to the lens arrangement (120). The configuration of elements (110, 130, 200, 260) provides for independent adjustment of relative lateral position between the optical fiber arrangement (220, 230) and the lens arrangement (120) in relation to axial position of the optical fiber arrangement (220, 230) relative to the lens arrangement (120). Such independent adjustment assists in fabrication of the assembly (100).

Embodiments of the present disclosure provide techniques for a fiber optic connector assembly configured for polarity reversal in accordance with some embodiments. An assembly may include a housing to receive a fiber optic cable, at least one back post connected with the housing, a ferrule including at least an optical fiber of the fiber optic cable, insertable into the back post, and a connector component comprising a front housing. The front housing may hold at least a portion of the ferrule and detachably couple with the back post. The back post may include a retaining element to provide rotatable coupling of the front housing relative to the ferrule, the back post and the housing. Other embodiments may be described and/or claimed.

A fiber optic connector assembly incorporates features that improve structural rigidity and the integrity of transmitted signals. These features also facilitate a technique for reversing polarity of the connector assembly with little or no risk of twisting the optical fibers and without requiring the housing assembly to be disassembled. The connector is marked or embossed with transmit and receive connector labels that facilitate visual identification of the polarity of the connector. One side of the duplex connector can be marked with “A” and “B” labels corresponding to the receive and transmit connectors, respectively. The opposite side of the duplex connector can be marked with two “A” labels corresponding to the receive and transmit connectors, respectively. Thus, a user can readily identify whether the connector is configured for “A-B” polarity or “A-A” polarity.
