Paper Abstract

The test results presented were obtained over a 9 month period at the Naval Electronics Laboratory Center at San Diego. The test objective was to assess the structural and other physical property characteristics of non-coherent, plastic jacketed, glass fiber-optic cable types of current manufacture. Tests were conducted to evaluate the capabilities of these type products to sustain structural integrity and operability after subjection to test exposures simulating Naval shipboard environmental conditions. The guide for these test conditions was either existing Military Standards and Specifications, where appropriate, or assigned test levels believed to be in excess of operational requirements. A total of 29 types of tests were performed utilizing over 200 fiber optic cables. A major part of this task involved the development of diagnostic test techniques for the evaluation of the test-induced cable property modifications. Tests of cable mechanical strength properties included bending radius, tensile, terminal, twist, mandrel, cyclic flexibility, vibration, mechanical shock and jacket abrasion. Test data analysis permitted determination of the limiting cable strength characteristics based upon measured 10 percent fiber breakage levels. Environmental tests performed consisted of thermal cycle and extended high and low temperature regimes, humidity cycle and steady state profiles and salt fog exposures. Chemical bath immersion tests included salt, mineral oil, sodium hydroxide and sulphuric acid as tests reagents. Results obtained from these tests demonstrated the ability of these type products to with-stand a wide range of physical exposures. Generally, it is concluded that the difficulties associated with the present utilization of fiber optic cables for many Naval applications are not as much related to limitations in the physical properties of these cables as they are to the lack of component and system manufacturing technology in this field. A final report detailing the fiber opticcable performance obtained in this test program is available by writing either to the author at Code 4400, or Library, Naval Electronics Laboratory Center, San Diego, California 92152. The report is entitled "Fiber Optic Cable Test Evaluation" and identified as NELC TR-1869.
