NVIDIA Mellanox MFS1200-C100 QSFP28 Active Optical Cable, 100GbE, 100m, LSZH: This is a 100-meter active optical cable (AOC) in QSFP28 form factor for 100GbE Ethernet point-to-point connectivity. The cable uses VCSEL optics over multi-mode fiber with a Low Smoke Zero Halogen (LSZH) jacket. This is a fixed-length integrated assembly with permanently attached transceivers, not a transceiver pair with a separate patch cord. This is a refurbished unit.
Engineering Context
The MFS1200-C100 uses 850nm VCSEL optics with 4x25Gb/s NRZ signaling to deliver 100GbE over 100m of multi-mode fiber. At 100 meters, this AOC is positioned for cross-row and end-of-row data center connectivity where passive and active copper cannot reach. The active assembly delivers complete electromagnetic isolation, lightweight bend-tolerant fiber, and negligible insertion loss compared to discrete transceiver-and-patch-cord deployments. The LSZH jacket complies with strict data center fire safety codes.
Deployment & Use Cases
Cross-row 100GbE Ethernet aggregation between data hall pods. Long-reach ToR-to-spine or leaf-to-spine connectivity in large fabric topologies. End-of-row 100GbE storage backhaul for object storage and Lustre clusters. Inter-room data center connectivity where dedicated patch panels are not present.
