Lumen Transports 1.2 Tbps Signal Across 1,800 Miles

Lumen Technologies and Ciena have collaborated on a successful 1.2 terabit wavelength service trial across 3,050 kilometers (more than 1,800 miles) on Lumen’s Ultra-Low-Loss fiber network, the longest 1.2 Tbps non-regenerated signal across the globe. Lumen and Ciena used 800G interfaces to successfully test and qualify the services to support wavelength, Ethernet, and IP services over the 1.2 Tbps single carrier channel. According to Lumen, the successful trial is important because artificial intelligence (AI), cloud, and security demands are pushing data transmission speeds to new limits. The jump to 1.2 Tbps wavelength services unlocks next-gen AI, cloud and data-intensive applications while improving scalability and network efficiency, an important development for hyperscalers and similar enterprises.
