Abstract

Network survivability is an issue of great concern to a telecommunications industry eager to deploy high-capacity fiber networks, since loss of services in high-capacity fiber systems due to disasters and catastrophic failures could be devastating and could result in significant revenue loss as well. Reducing network costs while maintaining an acceptable level of survivability has become an important task for network planners and engineers. Passive optical technology has been demonstrated as practical in reducing survivable fiber network costs. This paper discusses network use of power splitters, optical switches, and optical amplifiers in achieving self-healing networks.
