The Federal Telecommunications Standards Cammi ttee, chaired by the Office of the Manager, National Communications System, has established a Fiber Optics Task Group, one purpose of which is to develop guidelines for Federal agencies planning to use fiber optics in on-premises communications upgrades. This report describes the key technical elements under consideration in the Task Group. These technical elements include local area networks (LANs), digital private automatic branch exchanges (PABXs), building-wiring distribution architecture, and the application of optical fiber waveguides in the implementation of these on-premises systems. Each of these technical elements is undergoing rapid technological change.
This report develops some fundamental principles necessary to do tradeoff analyses required to make decisions regarding cost versus early technological obsolescence, Some examples of commercially available technology representing the present state of the art are included. Brief summaries of technology readiness, as presented by several key industry representatives to the Fiber Optics Task Group, are provided.
