Abstract: This disclosure describes techniques for attaching a connector to a fiber optic cable. As described herein, lengthwise slits are made into the jacket and the buffer tube of a fiber optic cable, thereby exposing interior segments of the optical fibers of the fiber optic cable. A loop is then made in the fiber optic cable at the slits. The ends of the optical fibers can then telescopically slide out the end of the fiber optic cable. When this happens, the exposed interior segments of the optical fibers slide out of the buffer tube and the jacket through the slits, forming a smaller loop within the loop. A connector may then be attached to the exposed ends of the optical fibers. When the fiber optic cable is unlooped, the exposed interior segments of the optical fibers slide back into the buffer tube and jacket. The jacket may then be resealed.
