🌟 NVIDIA Mellanox® MFA1A00-C020
QSFP28 Active Optical Cable | 100GbE | 20m | LSZH | Ethernet
NVIDIA P/N: 980-9I13F-00C020Product Overview
The NVIDIA Mellanox® MFA1A00-C020 is a 20-meter QSFP28 Active Optical Cable (AOC) engineered for long-reach 100Gb Ethernet (100GbE) connectivity in enterprise data centers, cloud infrastructures, and high-performance computing environments.
At 20 meters, copper DAC solutions are no longer viable. This AOC provides optical signal integrity, reduced weight, improved airflow, and consistent low latency, making it the correct engineering solution for extended in-rack, cross-rack, and end-of-row Ethernet connections.
The LSZH jacket ensures compliance with strict fire-safety regulations, making the cable suitable for hyperscale, colocation, and enterprise facilities.
