Medium voltage AC remote powering of access network equipment

Ten years ago, more than 90% of the power consumption took place in the central office and 10% in the access network and customer equipment. This situation is likely to be inverted in the next decade. Reliable and cost effective powering is a challenge for the rollout of active equipment in the outside plant. Operator independence from power utility companies as well as added flexibility in powering the equipment are key issues. This paper shows the results obtained in a EURESCOM project and should ease the evaluation, specification, design and implementation of a novel remote-powering scheme for the active external cabinet.
