Design of Embedded and Decentralized DC and AC Power Source Solutions for Each ICT Load Within a Unified Chassis Architecture

Abstract

Telecommunications technologies and equipment, including 5G infrastructure, OLTs, Transmission DWDM, IP/MPLS (CISCO, Juniper) systems, and IGW equipment, typically rely on standalone DC power systems at core sites, exchanges, MSC sites, BSC sites, long-distance sites, and microwave sites. As technology advances, there is an increasing need to implement decentralized DC systems at the equipment level, coupled with backup energy solutions in the form of BB’s either Sealed, Flooded or lithium-ion battery type systems. This decentralized approach not only mitigates the risks associated with a single point of failure but also improves the resilience and efficiency of telecommunications infrastructure. Furthermore, it improves resource utilization, accelerates the deployment of new technologies, and offers cost savings by enhancing overall system performance and reducing the dependency on large, centralized backup power solutions. This paper aims to explore the integration of small power plants and UPS systems directly embedded within telecommunications equipment, eliminating the risk of single point failures.
