There are now several options for 400 Gb/s applications. Driven by hyperscale cloud data centers, ongoing developments in 800 Gb/s, 1.6 Tb/s, and future 3.2 Tb/s are leading to additional advancements in optical fiber technologies and the need for high-performance connectivity. By James Young, CDCP 18 Enterprise Data Centers Can Repatriate and Digitally Transform with Familiar Cabling Solutions: Discover how to navigate the complex landscape of data center design and deployment options, including the practice of cloud repatriation that has most enterprise organizations adopting a hybrid approach where computing, storage, and services are comprised of both the public and private clouds. By Gary Bernstein, RCDD, CDCD 30 Testing and Troubleshooting Data Center Cable Plants: ICT data center professionals, installers, and technicians will first learn about the nuances of testing and troubleshooting cabling in data center environments. Then, they will explore many real-world situations where an all-in-one copper and optical fiber test and measurement tool can also perform common network identification and troubleshooting tasks. By Andrew Froehlich and Lisa Schwartz 42 Network Design for Greenfield Data Centers: Any greenfield data center will become a brownfield when it reaches its first tech refresh. For many data centers, that refresh cycle can occur every three to five years, so planning now will ensure the most cost-effective design with the least disruption. Infra- structure manufacturers can provide assistance when creating a forward-looking network migration plan to ensure that a network design, built from the ground up today, will be ready for change in the years to come. By Mike Connaughton, RCDD, CDCD 52 Keeping Your Cool by Optimizing Thermal Performance in a Connected World: Effectively managing power and keeping racks or cabinets, and the components within them, cool is a key challenge for today's data center engineers. ICT data center professionals must understand the growing need for more power, new cable requirements, and the latest cooling options, as well as the current state and limita- tions of those cooling options in order to address the future possibilities of thermal management. By Hasan Ali and Keegan McGraw 60 Strategies for Success for Data Center Construction Sustainability: In 2015, the Paris Agreement's goal was to limit global warming to two degrees Celsius above pre-industrial levels, but in the years since then, global emissions have continued to rise. Learn what to do to reverse this trend through green certifications, such as LEED, because credentialed BICSI designers, installers, and project managers will inevitably work with data centers pursuing this most popular credential in their sustainability journey.
