🌟 NVIDIA Mellanox® MFA1A00-C003
QSFP28 Active Optical Cable | 100GbE | 3m | LSZH | Ethernet
NVIDIA P/N: 980-9I13S-00C003
The NVIDIA Mellanox® MFA1A00-C003 is a 100GbE QSFP28 Active Optical Cable (AOC) designed for short-reach, high-bandwidth Ethernet connectivity in modern data centers.
Unlike passive copper DACs, this fiber-based AOC provides excellent signal integrity, lower cable weight, and superior EMI immunity, making it ideal for dense racks and high-speed switch-to-switch or switch-to-server connections.
With a 3-meter reach and LSZH jacket, the MFA1A00-C003 is optimized for safe, flexible deployments where copper cabling becomes bulky or signal-limited.

🧠 Why Use AOC Instead of DAC?
Lighter & thinner than copper DACs
Better signal quality at 100GbE
No EMI issues in dense racks
Easier cable management
Lower bit-error rates at longer short-reach distances
AOCs are often preferred once DACs exceed 2–3 meters.
