Reliability evaluation of survivable fiber optic networks [aircraft LANs]

Five kinds of fiber optic network architectures are studied from viewpoint of reliability and survivability (connectivity) under normal and abnormal situations. In normal situation we derive formulas for calculating average number of terminals which can communicate when one component fails. And in abnormal situation we calculate NCF and FCF which reflect network connectivity. On the basis of the analysis, some criterion are presented for designing survivable fiber optic networks.
