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 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.
