NVIDIA Mellanox MFS1S00-V020E 200GbE QSFP56 Active Optical Cable, 20m LSZH: This is a 20-meter active optical cable (AOC) for 200Gb/s Ethernet (200GbE) point-to-point links. The cable uses VCSEL optics over multi-mode fiber with a Low Smoke Zero Halogen (LSZH) jacket and QSFP56 connectors on both ends. NVIDIA P/N 980-9I44T-00V020. This is a fixed-length integrated assembly, not a transceiver with a detachable patch cord. This is a refurbished unit tested by T.E.S IT-SOLUTIONS.
Engineering Context
The MFS1S00-V020E uses 4 lanes of 50Gb/s PAM4 signalling to deliver 200GbE per cable. At 20 meters it provides cross-row reach where DAC copper is not viable due to weight, bend radius, and signal loss. The factory-terminated AOC removes patch-cable dirty-fiber failure modes that affect transceiver-plus-patch-cord deployments. The LSZH jacket meets data center fire-safety codes for cable trays and overhead routing. The cable is keyed for QSFP56 ports.
Deployment & Use Cases
Cross-row 200GbE Ethernet between data hall pods. ConnectX-6 Dx and ConnectX-7 200GbE adapter uplinks to NVIDIA Spectrum-2 (SN3000) and Spectrum-3 (SN4000) switches. Spine-leaf 200GbE fabrics where reach exceeds passive copper. AI training cluster Ethernet storage links and GPU-to-storage interconnects.
