Molex 2023 11 The need for additional training also causes a significant cost impact. Making the most of the greater performance on offer requires a new set of skills, and organizations will need to invest in training their staff to deploy and manage 400G Ethernet networks correctly. Organizations must also consider the compatibility of their existing networks when deploying new technology. The transceivers and connectors required may not be compatible with existing equipment, making it difficult for organizations to upgrade their networks to support 400G Ethernet. As well, system architects should consider the impact of 400G Ethernet on power and thermal management infrastructure. The equipment delivering greater performance requires more power and generates more heat. The cost of upgrading existing power networks and the effort needed to provide sufficient cooling will be high. Finally, 400G Ethernet standards are still evolving, and many companies will be wary of adopting new equipment in its early development stages. Companies may delay purchasing decisions because they cannot determine which equipment and technologies comply with the latest standards. As this technology is still in its early stages, few existing customers are employing it. The lack of real-world testing can be a concern for companies that cannot assess its performance and reliability. Beyond 400G As powerful as 400G Ethernet is, it is the latest development on the path to the faster systems of the future. After 400G, the next steps—800G and 1.6 Terabit Ethernet—are already being considered. These faster systems will be able to support even more data-intensive applications, such as real-time video streaming, virtual reality, and other applications that require extremely low latency and high bandwidth. It is also important to remember that this new technology will also play a key part in the roll-out of robust 5G networks, as the high speed and low latency required for 5G communications are similar to the demands of 400G Ethernet. Conclusion 400 Gigabit Ethernet is a relatively new technology, and its adoption is still in its early phases. Although not widely adopted, it is expected to gain broader adoption in the coming years. The key drivers behind adopting this new technology will be the demands created by data-intensive applications, such as AI, cloud computing, big data analytics, and high-definition video streaming. These applications are becoming increasingly popular, and as a result, the demand for high-bandwidth, low- latency connections will also increase. Some early adopters, such as large internet and cloud service providers, already use this new technology in their data centers. For other organizations, the relatively high cost of new equipment and the skills required to implement them to their full potential are significant concerns. These customers need partners who can understand and support their needs with the latest technologies. Molex's latest QSFP-DD connectors and DACs will deliver the performance needed for next-generation data centers that demand ever-faster speeds without compromising flexibility, agility, or quality. Building on decades of experience in data centers, delivering seamless integration between servers, networks, and storage, Molex can provide the strategy and technologies to help organizations master unprecedented new levels of data and leverage new opportunities. n " " We share and consume data freely and rely on telecommunications infrastructure to deliver the performance needed by the latest generation of equipment.
