Abstract

The Navy's commitment to the application of data bus technology to shipboard internal communication stems from the necessity of reducing cable congestion and weight. The Shipboard Data Multiplex System is a general purpose data bus system intended to take the place of most of the point-to-point cabling and associated hardware presently used for information transfer aboard ships of the Fleet. It uses both frequency and time multiplexing of a two-level set of redundant interconnections to provide a highly reliable data bus capable of distributing all forms of periodic and aperiodic signals. We report here a demonstration of the feasibility of substituting fiber optics for the coaxial cable presently used by this system. Primary concerns were whether the interface hardware could handle the FDM signals on the bus without excessive distortion and degradation of their signal to noise ratios. This paper describes methods used to demonstrate that the intermodulation distortion and signal-to-noise ratio requirements of the SDMS can be met by the necessary interface components.
