The number of broadband subscribers continues to grow worldwide, while the offerings provided by cable operators are also growing. The growth of reliable high-speed broadband access is changing the world both socially and economically for the better, while creating the challenge of curbing increased energy consumption. Within the Energy 2020 Initiative, the SCTE 186 Standard is looking for a two-pronged equipment approach as it pertains to equipment manufacturers. The approach includes the replacement of existing plant and headend gear with more efficient equipment as part of normal operational maintenance and the design and deployment of more efficient equipment. It focuses on improving energy efficiency and reducing operating costs. Generation 3 broadband power supplies, a newest-generation power platform, maximize network efficiencies in at least three specific areas: line efficiency, inverter efficiency and output voltage and output voltage and regulation.
