Advanced Fiber Information System

The Advanced Fiber Information System (AFIS) [66] contains a mechanism for opening a hand fed ribbon of fibers so that individual fibers can be presented aerodynamically to an electro-optical system for measuring fiber length. Length measurements for 10,000 individual fibers can be obtained in 5 min. 

Given the existence of interphases and the multiplicity of components and reactions that interact to form it, a predictive model for a priori prediction of composition, size, structure or behavior is not possible at this time except for the simplest of systems. An in-situ probe that can interogate the interphase and provide spatial chemical and morphological information does not exist. Interfacial static mechanical properties, fracture properties and environmental resistance have been shown to be grealy affected by the interphase. Careful analytical interfacial investigations will be required to quantify the interphase structure. With the proper amount of information, progress may be made to advance the ability to design composite materials in which the interphase can be considered as a material variable so that the proper relationship between composite components will be modified to include the interphase as well as the fiber and matrix (Fig. 26). 

Fiber in the horizontal is a reality because of the recent advances in technology easing installation, reducing the overall system cost, and offering a system that is reliable, flexible, certifiable, and future proofed for the information era. Aminimum of a two-fiber, 62.5-/zm cable is recommended for data communications and a separate category 3 UTP cable for voice. In determining the fiber count of the horizontal data cables, there are two distinct network possibilities.
