NVIDIA Mellanox MFS1S00-V003E 200GbE QSFP56 Active Optical Cable, 3m LSZH: This is a 3-meter active optical cable (AOC) engineered for 200Gb/s Ethernet (200GbE) point-to-point interconnects. 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 QSFP56 connectors molded onto each end, not a transceiver pair with a detachable patch cord. This is a refurbished unit, tested by T.E.S IT-SOLUTIONS.
Engineering Context
The MFS1S00-V003E uses 4×50Gb/s PAM4 signaling per direction to deliver 200GbE over a single QSFP56 connector. At 3 meters, it is positioned for short-reach intra-rack and adjacent-rack connections where DACs may be too rigid or too thick to route cleanly. The active optical assembly removes the need for separate transceivers and patch cords, reducing connector loss budgets and simplifying installation. The LSZH jacket keeps the cable compliant with strict data center fire and toxicity requirements. The cable is power-fed by the host port and consumes a few watts on each end.
Deployment & Use Cases
Top-of-Rack to spine 200GbE Ethernet uplinks. GPU server to leaf switch attachment in AI training pods. East-west fabric interconnect inside Spectrum-2 / Spectrum-3 leaf-spine designs. NVMe-oF and RoCEv2 storage backbones requiring deterministic 200GbE links. Migration paths from 100GbE QSFP28 to 200GbE QSFP56 within the same rack neighborhood.
