NVIDIA Mellanox MFS1S00-H020V 200G HDR/200GbE QSFP56 AOC, 20m: This is a 20-meter Active Optical Cable (AOC) supporting both InfiniBand HDR and 200Gb Ethernet at 200Gb/s between QSFP56 ports. The cable is a fixed-length factory-terminated VPI assembly using multi-mode fiber and integrated optics. This is not a transceiver pair with a detachable MPO patch cord and not a passive copper cable. This is a refurbished unit.
Engineering Context
The MFS1S00-H020V carries 200Gb/s as 4 lanes of 50Gb/s PAM4 over multi-mode fiber. At 20m the AOC bridges spans where copper DACs cannot maintain signal integrity for PAM4 modulation. The integrated optics deliver complete EMI immunity along the run, which matters when cable trays cross power distribution. The cable is significantly lighter than a copper bundle, reducing tray load on multi-rack runs. As a VPI assembly it can operate in InfiniBand HDR or 200GbE mode based on the host port configuration.
Deployment & Use Cases
Inter-row links between End-of-Row (EoR) switches and core or spine switches. HPC cluster expansion connecting compute islands into a unified HDR fabric. Spine-to-leaf 200GbE Ethernet aggregation in Spectrum-2 and Spectrum-3 deployments. AI training cluster east-west traffic between GPU server pods and storage fabric over multi-row spans.
Technical Specifications
OEM: NVIDIA Mellanox
Part Number: MFS1S00-H020V
Form Factor: QSFP56 to QSFP56
Data Rate: 200Gb/s (4x 50Gb/s PAM4)
Cable Type: Active Optical Cable (AOC), Multi-mode Fiber
Length: 20 meters
Protocol: InfiniBand HDR / 200GbE Ethernet (VPI)
Power: Active (host-powered)
Condition: Refurbished — Tested by T.E.S IT-SOLUTIONS
Compatibility & Hard Constraints
Compatible with NVIDIA Quantum HDR series InfiniBand switches (QM8700, QM8790), NVIDIA Spectrum-2 and Spectrum-3 Ethernet switches (SN3000, SN4000 families), and ConnectX-6 VPI adapters when ports are configured for 200Gb/s PAM4 operation. Requires the host port protocol (InfiniBand or Ethernet) to be set correctly for the link to come up. Not compatible with QSFP28 100G ports operating in NRZ-only mode. Not a breakout cable — direct QSFP56-to-QSFP56 only. Fixed 20m length.
