Available Configurations

APX-SW-AI-64Q

A 1U fixed switch for AI and high-performance computing fabrics, with 64×400G QSFP112 ports, lossless RoCEv2 networking and dynamic DCQCN tuning for congestion-sensitive workloads.

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.
