NVIDIA Mellanox MFA1A00-C010 100GbE QSFP28 Active Optical Cable, 10m LSZH: This is a 10-meter active optical cable (AOC) engineered for 100Gb/s Ethernet (100GbE) point-to-point interconnectivity. The cable uses VCSEL optics over multi-mode fiber with a Low Smoke Zero Halogen (LSZH) jacket. This is a fixed-length integrated assembly, not a transceiver pair with a detachable patch cord. This is a brand-new sealed unit.
Engineering Context
At 10 meters, this AOC sits in the band where passive copper QSFP28 DACs become impractical (the typical passive copper limit at 100Gb/s is around 3m; AOC takes over for 5m and longer). The cable uses 4 × 25G NRZ signaling, the standard 100GbE QSFP28 lane scheme. The integrated assembly eliminates fiber end-face cleaning steps and the failure modes of dirty MPO jumpers. AOC weighs roughly one tenth of an equivalent QSFP28 DAC bundle, which materially improves airflow and reduces mechanical stress on QSFP28 cages. BER is rated at less than 1E-15, and the LSZH jacket meets data center fire-safety mandates.
Deployment & Use Cases
Top-of-Rack to End-of-Row 100GbE Ethernet links inside a data hall. Connecting GPU compute nodes (DGX, HGX) to 100GbE leaf switches across rack spans. Spine-leaf Ethernet links where reach exceeds the 3m passive copper limit. Storage cluster front-ends running NVMe-over-Fabrics RoCEv2 between racks. Build-outs in colocation and hyperscale facilities with strict LSZH cable mandates.

Compatibility & Hard Constraints
Compatible with NVIDIA Spectrum series Ethernet switches (SN2000, SN3000, SN4000) and ConnectX-4 / ConnectX-5 / ConnectX-6 Dx EN adapters. Both ports must be configured for 100GbE Ethernet. Not compatible with InfiniBand EDR ports unless the switch supports VPI mode reconfiguration to Ethernet. Not compatible with SFP28 ports, and not interoperable with standard 40GbE on both ends without FEC adjustments. This is a direct QSFP28-to-QSFP28 cable; it does not support 4 × 25G breakout. Length is fixed at 10m — there is no on-cable splice or extension.
Frequently Asked Questions (FAQ)
Q. What is the MFA1A00-C010?
The MFA1A00-C010 is a 10m active optical cable with QSFP28 connectors, rated for 100GbE Ethernet, LSZH jacket.
Q. Is this a splitter cable?
No. It is a straight 1-to-1 QSFP28-to-QSFP28 point-to-point assembly.
Q. Will T.E.S IT-SOLUTIONS confirm the configuration of MFA1A00-C010 before shipping?
Yes. T.E.S IT-SOLUTIONS (tes-itsolutions.com) bench-tests each unit where test topology is available, before dispatch from EU stock.
