Connectors for micro-duct terminations of fiber optic cable

An optical fiber feed-through connector for optically coupling an end portion of an optical fiber cable with a non-feed-through optical fiber connector comprising:

• a feed-through duct engaging portion having a body member and a compression fitting portion configured to axially move between a first position, where the feed-through duct engaging portion is configured to receive a free end portion of a duct shaped to allow an end portion of an optical fiber cable to be slidingly fed through the duct, and a second position, where the compression fitting portion is configured to radially compress a portion of the body member around the free end portion of the duct, the feed-through engaging portion being configured to permit the end portion of the optical fiber cable to be slidingly fed through both the duct and the feed-through duct engaging portion in the first position and the second position;
• a feed-through housing portion configured to be operatively coupled to the feed-through duct engaging portion so as to allow the end portion of the optical fiber cable to be slidingly fed through the feed-through housing portion;
• and
• wherein the feed-through duct engaging portion and the feed-through housing portion are configured to permit the optical fiber cable to be pushed or pulled through the duct and the feed-through housing portion after the feed-through duct engaging portion is operatively coupled to the feed-through housing portion.
