Abstract

New and emerging telecommunications access networks may require network termination units (NTUs) to be back-up powered, especially for telephony service provision. The multiplicity of NTUs, located at or near customers´ premises, dictates the need for both low capital and operational costs. Powering an NTU with photovoltaic cells and supercapacitors is expected to achieve a low life-cycle cost. This paper introduces the requirements for NTU powering, then develops photovoltaic cell and supercapacitor component models and investigates their application to powering an NTU
