Summary form only given. Ring topologies have recently emerged as the preferred architectures for wavelength-division multiplexing (WDM) networks because of the survivability capabilities they provide and the fact that their capacity can be shared by all the nodes connected to a ring. This report focuses on four-fiber WDM self-healing ring (SHR) architectures in which restoration from a failure is achieved using automatic protection switching loop-back systems. A similar approach is also usable for two-fiber WDM SHRs except that the number of wavelengths required doubles.
