NVIDIA Mellanox LinkX 400GbE QSFP112 to OSFP Active Optical Cable

The NVIDIA Mellanox LinkX 400GbE QSFP112 to OSFP Active Optical Cable delivers ultra-low-latency, high-bandwidth interconnectivity for next-generation data center architectures. This active optical cable (AOC) bridges QSFP112 and OSFP connector standards, enabling seamless integration across GPU-accelerated compute clusters and high-performance networking fabrics operating at 400 Gigabit Ethernet line rates.

Designed for demanding enterprise AI, machine learning, and HPC workloads, the LinkX AOC provides reliable signal integrity over extended reaches with integrated transceiver compensation and thermal management. The cable architecture supports full-duplex operation with minimal insertion loss, optimizing throughput for demanding inter-rack and intra-rack GPU-to-GPU communication patterns.

This solution addresses the critical interconnect bottleneck in modern accelerated data centers by offering deterministic, low-latency performance required for distributed training, real-time inference, and batch processing at scale.

Ideal for

• GPU cluster interconnects for large-scale distributed deep learning and foundation model training
• High-performance computing (HPC) node-to-node communication in tightly coupled parallel workloads
• Data center fabric upgrades enabling 400G spine-to-leaf architectures with GPU server endpoints
• AI inference platforms requiring ultra-low inter-node latency for real-time model serving
• Storage-acceleration use cases connecting GPU nodes to NVMe or persistent memory arrays
• Multi-tenant cloud infrastructure supporting isolated 400G virtual network segments
