The Next Linear Collider accelerator will require phase synchronization of {approximately} 20{degree}X-band (11.424 GHz) long term, and {approximately} 1{degree}X-band short term throughout its 30 kilometer length. A prototype fiber optic distribution system has been constructed to demonstrate this level of performance. This system operates by measuring the optical round trip time in the fiber, and then controlling the fiber phase length to stabilize this measurement. The authors describe the design of this system, and show recent results on stability and phase noise.
