400G & 800G ZR/ZR+ Solutions
Coherent Optical Connectivity for DCI
As AI clusters continue to scale and data center architectures expand across regions, the need for high-bandwidth, power-efficient connectivity has never been greater. Proficium’s 400G and 800G ZR/ZR+ coherent optical transceivers enable high-capacity Data Center Interconnect (DCI) deployments using compact pluggable optics, helping organizations connect facilities across metro, regional and long-haul networks without the complexity of traditional transport platforms. Designed for hyperscale, cloud, AI/ML and high-performance computing environments, Proficium ZR and ZR+ solutions provide a scalable path to greater bandwidth, lower latency and simplified network architectures.
