🌟 NVIDIA Mellanox® MFA1A00-C005
QSFP28 Active Optical Cable | 100GbE | 5m | LSZH | Ethernet
NVIDIA P/N: 980-9I13X-00C005
The NVIDIA Mellanox® MFA1A00-C005 is a 100GbE QSFP28 Active Optical Cable (AOC) designed for short-to-mid-reach Ethernet connectivity in modern data centers, enterprise networks, and HPC environments.
At 5 meters, this AOC provides a clear advantage over passive copper DACs, delivering superior signal integrity, lighter weight, and improved cable manageability. Integrated optical transceivers at both ends handle signal conversion, enabling stable 100Gb/s transmission without the bulk or distance limitations of copper.
The LSZH jacket ensures compliance with stringent safety standards, while programmable signal-conditioning features allow fine-tuning of performance in demanding or heterogeneous network deployments.

🧠 Why Choose a 5m AOC Instead of DAC?
Better signal quality at longer short-reach distances
Much thinner and lighter than copper DACs
Immune to EMI / crosstalk
Easier cable routing in dense racks
Preferred once DACs exceed 2–3 meters
For 100GbE links at 5m, AOC is the correct engineering choice.
📐 Directionality
Bi-directional (QSFP28 ↔ QSFP28)
Plug-and-play for 100Gb Ethernet
🧩 Ideal Applications
Switch-to-switch 100GbE links
Switch-to-server / NIC connectivity
Top-of-Rack (ToR) and End-of-Row (EoR) deployments
