Infinera Corp. of Calif. and Fastweb, an Italian telecommunications operator, have successfully demonstrated 500-Gb/s (500G) single-wavelength service connectivity in a production network using Infinera’s configurable technology on the Groove platform. The high-speed optical transmission demonstration, the first in Italy, spanned over 180 km on Fastweb’s low-latency, long-haul backbone fiber network between Milan and Turin. The 500G trial demonstrated the company’s capability to scale its infrastructure network to meet the increasing bandwidth demands of its end-user customers. The trial was conducted over Fastweb’s existing optical infrastructure without special amplifiers, tuning, or changes. Infinera’s 7300 Multi-Haul Transport Platform, mTera Universal Switching Platform, and Groove 600G technology are part of Fastweb’s backbone network spanning over 650 nodes and providing the flexibility and future development and delivery of a range of programmable high-speed end-user services at 400G, 500G, and up to 600G. Infinera’s solution enables Fastweb to scale internet exchange point capacity up to 24 Tb/s, while offering ease of deployment and network investment efficiency.
