About Ciena Corporation

Ciena is a leader in high-speed optical connectivity, providing systems, components, and automation software for telecom providers and enterprises, such as data centers, to enable long-distance connectivity. The company operates through four primary business segments: networking platforms, platform software and services, Blue Planet automation software, and global services. While telecom carriers remain important customers, cloud providers and hyperscalers now drive a significant portion of the business. To meet the demands of AI data centers, customers are adopting Ciena's WaveLogic 6 platform, the first to support 1.6 terabits-per-second capacity.
