High-Value Application Scenarios
AI Training Clusters
800G links move massive training data between GPU servers and leaf switches, while the 2x 400GBASE-VSR4 breakout doubles effective port density for AI fabrics.
Data Center Interconnects
With 50m reach over multimode fiber, this module links racks and rows within a data center, keeping 800G throughput between distributed sites.
Spine-Leaf Deployments
As a spine or leaf uplink, the dual 400G breakout feeds two 400G leaf ports from one 800G OSFP slot, simplifying cabling and saving switch ports.
Cloud Data Centers
Cloud operators use 800G OSFP optics to scale out high-bandwidth fabrics, and this compatible module drops into Arista switches without requalification.
Compatibility
This module is compatible with Arista 7060X, 7280R, 7388 and 7800R series switches and other Arista platforms.
