This paper presents a comprehensive review of methods aimed at improving the energy efficiency (EE) of wired access passive optical networks (PONs) and active optical networks (AONs). We introduce MOSAIC, a novel optical link technology that breaks this trade-off. on a narrow-and-fast architecture with a few high-speed channels, MOSAIC adopts a wide-and-slow design, employing hundreds of par-allel. The rise of cloud computing, AI-driven applications, 4K and 8K video, and the Internet of Things (IoT) requires faster, more reliable, and energy-efficient transmission solutions. It utilizes optical fiber “between the connectors” to deliver the same electrical bandwidth that would be found in a significantly larger number of copper cables. Optical cables use light to transmit data and therefore the. Data Center Networks (DCNs) face challenges due to the exponential growth in data traffic driven by applications such as video streaming, artificial intelligence, machine learning, and cloud computing. Traditional electronic switches struggle to keep up with growing bandwidth and connectivity.
