Mellanox MFA1A00-C003 100GbE QSFP28 Active Optical Cable 3m

The Mellanox MFA1A00-C003 is a 100GbE QSFP28 Active Optical Cable (AOC) engineered for high-speed, low-latency interconnect in enterprise data center and HPC environments. The 3-meter cable leverages optical transmission to eliminate electrical signal degradation over extended distances, enabling reliable 100 Gigabit Ethernet connectivity across rack and inter-rack topologies without requiring external power or signal conditioning.

This AOC is optimized for GPU cluster interconnects, AI training infrastructure, and tightly-coupled HPC applications where deterministic latency and sustained throughput are critical. The active optical architecture supports full-duplex 100GbE operation with integrated transceiver logic at both ends, eliminating compatibility concerns associated with passive copper alternatives in high-density deployments.

The cable integrates seamlessly with Mellanox/NVIDIA ConnectX InfiniBand and Ethernet adapters, as well as compatible switching infrastructure. Its robust optical design handles the thermal and signal-integrity demands of modern accelerated computing clusters while maintaining backward compatibility with standard QSFP28 form factors.

Ideal for

• GPU-to-GPU interconnect within multi-node AI training clusters requiring sub-microsecond latency
• Spine-to-leaf fabric connectivity in 100GbE data center networks spanning 3-meter inter-rack distances
• High-performance computing (HPC) cluster node-to-node and node-to-storage interconnect
• InfiniBand EDR (Enhanced Data Rate) fabric extensions in scientific computing environments
• Machine learning model serving infrastructure with distributed inference across GPU pods
• Real-time analytics platforms requiring sustained 100GbE throughput with minimal packet loss
