Abstract:
Fiber optic telecommunication systems are susceptible to both natural and man-made stress. national Security/Emergency Preparedness (NSEP) is a function of how durable these systems are in light of projected levels of stress. Emergency Preparedness in 1987 is not just a matter of—can we deliver food, water, energy, and other essentials?—but can we deliver the vital information to maintain corporate function of our country? “Communication stamina” is a function of “probability of survival” when faced with stress. This report provides an overview of the enhancements to a fiber optic communication system/installation that will increase durability. These enhancements are groups, based on their value in protecting the system, such as a Multitier Specification is created that presents multiple levels of hardness. Mitigation of effects due to high altitude electromagnetic pulse (HEMP) and gamma radiation and protection from vandalism and weather events are discussed in this report. This study concludes that the probability of survival can be significantly increased with expeditious use of design and installation enhancements.
