Abstract
Currently, most regional Bell operating companies (RBOCs) favor centralized powering as the predominant method for powering fiber-in-the-loop (FITL) systems. This is because centralized power systems can provide indefinite power backup, as well as consolidation of power equipment and batteries. The capabilities of such a power system are dependent on several parameters including supply cable gauge, load requirements, and equipment location. This paper examines two centralized powering architectures and determines the impact of these parameters on the installed first cost of the power system. The paper also provides a review of the anticipated narrowband FITL power requirements and specifications.© (1992) COPYRIGHT SPIE--The International Society for Optical Engineering.
