Applications
🤖 AI and High-Performance Computing Fabrics
Provides a lossless 400G fabric for GPU clusters and distributed training, using RoCEv2, PFC and DCQCN to keep east-west traffic flowing without drops.
🏢 Data Center Spine-Leaf
Scales leaf and spine tiers with 400GE, 200GE, 100GE and 40GE options, VXLAN overlays and EVPN control for multi-tenant cloud infrastructure.
📡 Campus and Mobile Backhaul
Connects campus access switches over 10GE uplinks and carries 5G and LTE backhaul traffic on the IPRAN packet transport platform.
Compatibility
Interoperable with major optical transport and networking platforms. Standard Ethernet, IP routing, overlay and management interfaces let these switches and the IPRAN platform join existing data center, campus and mobile networks.
