Data center connectivity is the foundation of digitalization. Critical businesses, government activities and our daily lives all rely on data centers and so the network infrastructure interconnecting them and enabling access to storage data is a critical asset. Enterprises and organizations need data center interconnect (DCI) infrastructure that can accommodate ever-increasing data traffic. Moreover, with the growing number of cyberattacks, they also need a solution that protects data in motion between data centers against man-in-the-middle attacks. Our FSP 3000 S-Flex™ DWDM muxponder is specifically engineered to address these demands. With 400Gbit/s capacity, the support of a broad range of DCI protocols, and built-in quantum-safe encryption, it enables high-speed, scalable DCI networks that are highly reliable and secure even against quantum-computer attacks.
