Glossary of Optical Communication Terms

"This glossary was first published in June 1986 by the Engineering Division of the FAA Technical Center, under the title "Glossaryof Fiber Optic Terms" (Division Report CT-110-86-15). It has now been revised and expanded, and is made available for wider distribution. It is intended to be an introductory reference for those with a technical background (engineers, scientists, and technicians) who have an interest in optical communication, but are not familiar with some of the more common terms used in this field.

Emergency Classification

"An Emergency Classification is a set of plant conditions which indicate a level of risk to the public. Both nuclear power plants and research and test reactors use the four emergency classifications listed below in order of increasing severity. The vast majority of events reported to the NRC are routine in nature and do not require activation of our incident response program. Recognizing that security-related events may involve different response actions from the licensees, the NRC issued Bulletin 2005-02, Emergency Preparedness and Response Actions for Security-Based Events.
