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.

Abstract: A system comprises a first unit and a second unit communicatively coupled to the first unit. The first unit is operable to receive a first original radio frequency signal and the second unit is operable to receive a second original radio frequency signal. The first and second original radio frequency signals are originally transmitted on a radio frequency channel using time division duplexing. The first unit communicates a control signal to the second unit, the first unit generating the control signal based at least in part on detecting when the first original radio frequency signal is being received at the first unit. The second unit uses the control signal to determine when to output a first reproduced radio frequency signal in accordance with the time division duplexing used to originally transmit the first and second original radio frequency signals on the radio frequency channel. The first reproduced radio frequency signal is derived from the first original radio frequency signal.

Abstract: An optical fiber cable assembly comprising an optical fiber slidably enclosed within a hollow tubing, both the fiber and the tubing having corresponding first and second ends. The cable is terminated with the first and second ends of the tubing and the fiber constrained with respect to each other such that fiber and the tubing are approximately the same length when the cable is at a first temperature.

An intermediate portion of the tubing permits the excess fiber length to accumulate without bending in a radius smaller than a minimum bend radius.
