Abstract

Fiber-optic ring architectures have an inherent reliability problem when considered for spaceborne applications: a single-node failure can interrupt communications to every other node. The Fiber Distributed Data Interface (FDDI) protocol solves this problem through use of a dual counter-rotating ring architecture. This provides communication between all nodes, even if a single fault has occurred. If more than a single fault occurs, the ring can become segmented and communication is not provided to all nodes. This paper presents a dual cross- strapped ring architecture that provides the degree of survivability required for many spaceborne applications.
