Army Fiber Optic Program: An Update

Modernization of Army tactical communication systems has placed emphasis on meeting new digital data handling requirements. An all digital transmission facility will require new radio systems and substantially improved cable systems which can overcome present length-bandwidth limitations. These new digital systems must have, in addition, superior reliability, freedom from electromagnetic countermeasures, and be highly mobile. These requirements are driving the development of new distributed multiplexed radio systems and an intensive investigation into the utilization of fiber optic cable systems. Fiber optic cables have the required capabilities of: EMI, RFI, and crosstalk immunity, substantially reduced deployment weight and volume, and freedom from electromagnetic pulse effects. Recent developments in fiber technology have significantly reduced the risk associated with the use of fiber cable in a tactical field Army installation. However, there are some problems that need to be resolved before fiber optic systems can be fielded. This paper will discuss Army application areas, components and system development efforts directed toward fielding tactical fiber optic systems.
