A lightweight, tactical single-mode fiber optic cable was developed to meet specific optical and mechanical requirements for the battlefield environment. Several cable designs were tested to arrive at a 2.1 mm diameter cable using all-dielectric materials. The development of the present cable design was an iterative process using optical, mechanical, and environmental test results to arrive at the present cable design providing favorable mechanical performance without sacrificing optical performance. Mechanical tests such as tensile strength, impact, compressive load, and cyclic flexure were performed in accordance with DOD-STD-1678. The cables were temperature cycled in accordance with EIA-FOTP-72 to aid in material selection. This paper will present the development of the present cable design from the optical fiber selection to the jacket material and will include a summary of the cable designs tested, the testing performed, the development of manufacturing methods, and the selection rationale leading up to the present design.
