Phase Distribution on Fiber Optic Cable

Abstract

A fiber optics link has been tested for distributing stable phase information at a frequency of 216.98 MHz for the Kickapoo transmitter of the Naval Space Surveillance radar. Laboratory experiments have been carried out with a specially modified laser and no special precautions were taken to minimize reflections. The relative stability of different fibers in the same cable was tested with repeated cycling of the cable temperature. The relative stability of two fibers each 1 km in length over hundreds of hours including temperature changes of 25 kelvins was better than 25 psec peak-to-peak, or about 1 part in 200,000.
