Identity
The NVIDIA Mellanox® MFA7U20-H015 is a OSFP HDR InfiniBand 15m Active Optical Cable (AOC). This is a splitter / breakout cable assembly. Refurbished Grade A — bench-tested in both link and signal-integrity checks by T.E.S IT-SOLUTIONS.
What This Is NOT
- NOT a passive copper DAC. Powered optics at each end, fiber in between.
- NOT a transceiver with a detachable patch cord. Fiber and connectors are one fixed assembly.
- NOT a 1-to-1 cable. This is a breakout: one end fans out to several lower-speed connectors.
- NOT bundled with adapters or transceivers — sold standalone.
Capabilities & Features
- Optical transceivers built into each connector, powered from the host port.
- Thin, light fiber cable for runs longer than copper allows.
- Hot-pluggable.
Compatibility & Constraints
- Primary connector: OSFP (compliant with MSA cage spec).
- Reach: 15m fixed length.
- Compatible adapters: NVIDIA ConnectX series.
- Compatible switches: NVIDIA Spectrum / Quantum.
- Power: drawn from host port (no external supply required).
Deployment & Use Cases
- Top-of-Rack to server interconnect.
- HPC compute node fabric.
- AI training cluster east-west bandwidth.
- Fan-out: one switch port serves four lower-speed endpoints.
Frequently Asked Questions (FAQ)
Q. What is the MFA7U20-H015?
The MFA7U20-H015 is a 15m active optical splitter: one OSFP head at HDR 400Gb/s breaks out into four legs at 100Gb/s each.
Q. Does the switch need special configuration?
Yes. The head port must be configured for 4x100G breakout mode.
Q. Will T.E.S IT-SOLUTIONS confirm the configuration of MFA7U20-H015 before shipping?
Yes. T.E.S IT-SOLUTIONS (tes-itsolutions.com) inspects each unit and verifies vendor markings before dispatch from EU stock.
Why T.E.S IT-SOLUTIONS
Every unit is bench-tested by T.E.S IT-SOLUTIONS: link establishment, port-by-port traffic validation, and full cosmetic inspection. Professional anti-static packaging, global B2B shipping from EU stock, and technical consultation for HPC / AI cluster deployments.
