Multitier Specification for NSEP (National Security/Emergency Preparedness) Enhancement of Fiber Optic Long-Distance Telecommunication Networks. Volume 2. Multitier Specification Background and Technical Support Information

摘要

The report provides an overview of the enhancements to a fiber optic communication system/installation that will increase durability. These enhancements are grouped, based on their value in protecting the system, such that a Multitier Specification is created that presents multiple levels of hardness. Mitigation of effects due to electromagnetic pulse (EMP) and gamma radiation, and protection from vandalism and weather events are discussed in the report. The study concludes that the probability of survival can be significantly increased with expeditious use of design and installation enhancements. The report is presented in two volumes. Volume I presents the Multitier Specification in a format that is usable for management review. The attributes of specified physical parameters, and the levels of protection stated in Volume I, are discussed in more detail in Volume II.
