Abstract
A fiber optic connector is disclosed that includes a plug body having a plug end and a connector core that mounts within the plug body. The connector core includes a ferrule subassembly including a ferrule, a ferrule hub that attaches to the ferrule, a spring holder and a connector spring. The ferrule sub-assembly is assembled with the connector spring pre-compressed to an initial compressed state prior to mounting the connector core within the connector body. The plug body and the core are configured such that the connector spring is moved from the initial compressed state to a final compressed state when the connector core is loaded in the plug body. In certain examples, tuning features can be integrated into the connector core.

16. A fiber optic connector core comprising:
-
a ferrule subassembly including a ferrule supporting an optical fiber along a ferrule axis, a ferrule hub attached to the ferrule, a spring holder that attaches to the ferrule hub and a spring captured between the spring holder and the ferrule hub, and the ferrule being non-rotatable about the ferrule axis relative to the ferrule hub and the spring holder; a cable anchor configured to be anchored to a fiber optic cable; and the ferrule subassembly having a plurality of different rotational mounting positions about the ferrule axis relative to the cable anchor, wherein during assembly tuning is accomplished by securing the ferrule subassembly in a suitable rotational mounting position where a core offset of the optical fiber is oriented at a predetermined rotational position relative to the cable anchor. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. A tunable hardened fiber optic connector for attachment to a fiber optic cable having at least one strength member, the tunable hardened fiber optic connector comprising:
-
a connector core including a ferrule supporting an optical fiber, a ferrule hub secured to the ferrule and a cable anchor; a plug body that mounts over the connector core, the plug body having a plug end through which the ferrule extends when the plug body is mounted over the connector core such that an end face of the ferrule is accessible adjacent the plug end of the plug body; a fastening element mounted outside plug body for securing the tunable hardened fiber optic connector to a mating connector or adapter; the connector core being configured such that the ferrule can be pre-set in one of at least three different rotational tuning positions relative to the cable anchor prior to mounting the plug body over the connector core to tune the hardened fiber optic connector, wherein the pre-set one of the at least three different rotational tuning positions represents a tuned position of the ferrule; and the plug end of the plug body defining an internal feature that interfaces with the ferrule hub to rotationally lock the ferrule in the tuned position relative to the plug body. - View Dependent Claims (33, 34, 35, 37, 38, 39, 40, 41, 42, 43, 44)
