INTRODUCTION These methods are intended to simulate the effect of ice (Method A) or the crush force caused by ice (Method B) on Fiber Optic Cables. The primary purpose of this procedure is to measure any variation in optical power transmittance of a fiber optic cable when the cable is subjected to the potentially destructive forces of frozen water (ice) external to the cable jacket. A secondary purpose is to evaluate the possibility of physical damage that may occur as a result of such exposure.
