Abstract
A cross-channel data link for interconnecting a plurality of computers together in a ring configuration using a single optical fiber between adjacent communication nodes includes wavelength division multiplexing circuitry in a way that improves the fault diagnostic capabilities of the system. By using a particular transmission protocol in which optical data representing signals of two discrete wavelengths are fed through a single optical fiber with one progressing in the clockwise direction and the other in a counterclockwise direction in two recurring time frames, at the conclusion each of the computers is guaranteed to have identical data irrespective of any single point failure in the data link.
