Reducing Power Consumption in Optical Access Networks: Point-to-Point and Point-to-Multipoint Architecture Cases
Abstract
The growing demand for broadband services has led to the widespread deployment of optical access networks (OANs). However, as these networks expand, energy consumption is becoming an increasingly important economic and environmental issue. In this paper, we analyze the energy savings of the transition from a point-to-point (P2P) optical architecture to a gigabit-capable passive optical network (GPON) with a point-to-multipoint (P2MP) architecture. We present a comparative analysis of the energy requirements of both architectures, focusing on active and passive components, and evaluate their impact on overall energy consumption. Using a case study of the migration of a real optical network operator’s network, we show that power consumption decreased significantly after the introduction of GPON.
