摘要： A ferrule is provided that includes a ferrule body defining a longitudinally extending groove that can serve as an alignment feature for polishing operations. In this regard, the ferrule body extends longitudinally between opposed front and rear surfaces so that at least the rear surface generally defines a substantially rectangular shape in lateral cross-section. In addition, the ferrule body typically has first and second major sides and first and second minor sides with the first and second major sides being larger than the first and second minor sides. The ferrule body defines the longitudinally extending groove in at least one of the major surfaces. A jig is also provided for engaging the longitudinally extending groove defined by the ferrule body in order to hold the ferrule in an aligned position during polishing operations. In this regard, the jig includes a jig body having an alignment feature for engaging a complimentary alignment feature of the ferrule. The jig also includes a support element capable of engaging another side of the ferrule, wherein at least one of the jig body and the support element is capable of pivoting. By appropriately sizing those elements of the jig body and the support element that contact the ferrule, the contact elements can be inserted through openings defined by the connector housing such that the front surface of the ferrule can be precisely polished after the ferrule has been assembled into a fiber optic connector.

摘要： A cleaning tool for cleaning internal optical components of a fiber optic connector includes a cleaning strip that is advanced past one or more optical surfaces of the connector to wipe the connector free of contaminants. The cleaning tool includes a drive mechanism that is operated by rotating a drive, thereby advancing the cleaning strip along a cleaning strip path and into contact with the one or more optical surfaces. The cleaning tool comprises a cleaning tip that functions to place the cleaning strip in proper alignment within the connector in order to clean the optical surfaces that are not available for cleaning at the endface of the connector. Alignment features are provided in the cleaning tip to properly position the cleaning strip relative the optical surfaces.

In one embodiment, an optical connector includes a plug housing, at least one optical fiber, an internal coupling surface, and a translating element. The translating element has a first coupling surface, a second coupling surface, and at least one optical component within the translating element. The translating element is biased such that when the optical connector is in a disengaged state, the translating element is positioned toward an optical connector opening and the second coupling surface of the translating element is displaced from the internal coupling surface. When the optical connector is in an engaged state, the translating element is positioned such that the second coupling surface of the translating element is positioned at the internal coupling surface and the optical fiber is optically coupled to the optical component.
