NVIDIA Mellanox MFA2P10-A005 25GbE SFP28 Active Optical Cable, 5m LSZH: This is a 5-meter active optical cable (AOC) engineered for 25Gb/s Ethernet (25GbE) point-to-point interconnectivity between SFP28 ports. 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 with a detachable patch cord. NVIDIA P/N 980-9I53W-00A005. This is a refurbished unit.
Engineering Context
The MFA2P10-A005 carries 25GbE NRZ over a single optical lane between SFP28 cages. The active optical design eliminates the impedance and skew limitations of long passive copper assemblies and provides full electromagnetic immunity for runs near power distribution and high-density cable trays. The integrated transceivers are factory-aligned, removing the need for separate patch cords or end-face cleaning. The LSZH jacket meets data-center fire-safety codes where halogen-emitting jackets are not permitted. Total weight is significantly lower than equivalent passive twinax of the same length, reducing strain on switch cages.
Deployment & Use Cases
Top-of-Rack to server 25GbE uplinks where 5m exceeds reliable passive DAC reach. Connecting compute and storage nodes within the same row across cable trays. RDMA-over-Converged-Ethernet (RoCE) fabrics for distributed databases and virtualization clusters. Deployments that require LSZH-rated cabling for fire-safety compliance.
