Results of battery selection process performed for FTTC applications

Abstract

Power sources for remotely located electronics used in fiber optic public network distribution loops are considered. The author describes the selection process, presents the compared data, and analyzes the merits of today's battery technologies suitable for this application. The types of battery technologies compared are lead acid, nickel cadmium, and nickel hydrogen. The evaluation parameters used for the selection process include size, life cycle costs, capacity, voltage, and discharge characteristics, all of which are evaluated for performance from -40 degrees C to +65 degrees C. The life cycle costs include operations and maintenance incurred during a 20 year life.<>
