Increased demand for streaming services, data storage, analytics and cloud-based applications are driving the requirement for next-generation high-speed network access and data processing capabilities across cities, countries and continents. To manage these accelerating data rates and volumes, the industry is transitioning to the 400 Gigabit Ethernet (GbE) standard -- which incorporates a range of modules including 400ZR -- for faster switching and routing. Optical transceivers are the backbone of data movement; meeting the needs of all types of 400 GbE module assembly and reliability is critical and why more companies are choosing Henkel when it comes TOSA/ROSA assembly materials.
