Fiber optic dust cap and connector for terminating multi-fiber optical cables

A dust cap and an optical fiber connector, the dust cap adapted to cover a distal end of the optical fiber connector, the dust cap extending between a distal end and a proximal end, the dust cap and the optical fiber connector comprising:

• a sleeve of the dust cap, the sleeve having a central axis and defining a cavity for receiving the distal end of the optical fiber connector, the cavity extending along the central axis of the sleeve and having an open end positioned opposite from a closed end, the open end of the cavity providing the distal end of the optical fiber connector access to the cavity from the proximal end of the dust cap;
• at least one resilient latch of the dust cap within the cavity of the sleeve, the at least one resilient latch including a cantilevered arm with a free end and a base end, the base end connected to the sleeve, and the free end extending proximally from the base end, the at least one resilient latch further including a retainer mounted on the free end of the cantilevered arm;
• a connector body of the optical fiber connector, the connector body extending from a first end to a second end, the connector body defining an interior passage extending between the first and the second ends of the connector body, the interior passage adapted to receive optical fibers through the second end of the connector body, and the connector body including an exterior portion that defines a retaining pocket;
• a ferrule of the optical fiber connector, the ferrule adapted to receive and terminate at least one optical fiber;
• the ferrule positioned at least partially within the interior passage of the connector body;
• and the ferrule including a terminal end extending beyond the first end of the connector body;
• and
• a release sleeve of the optical fiber connector positioned over a portion of the connector body, the release sleeve extending from a first end to a second end, the first end of the release sleeve positioned nearer the first end of the connector body, the second end of the release sleeve positioned nearer the second end of the connector body, the release sleeve being slidingly mounted over the connector body;
• and the release sleeve being slidable between a latch position and a release position on the connector body;
• wherein the retainer of the at least one resilient latch of the dust cap is captured by the retaining pocket of the connector body and an interior portion of the release sleeve when the dust cap is installed on the optical fiber connector and the release sleeve is at the latch position;
• and
• wherein the captured retainer retains the installed dust cap on the optical fiber connector.
