Design approaches to power-over-optical local-area-network systems

摘要

This paper discusses fiber optic power and signal transmission systems considering the application of dc powering to information tools such as personal computers. We discuss system requirements and technical issues for the system components, including high-power laser diodes and photovoltaic cells. It is clarified that the conversion efficiencies of photovoltaic cells are kept constant with heat radiation and improve with extremely small series resistance. The transmittable optical powers through the optical fiber limited by a nonlinear optical effect are estimated. We also discuss the system designs for the use of single- and multi-mode optical fibers.
