Identity

The NVIDIA Mellanox® MCP7F80-W003 is a QSFP-DD 400GbE 3m Passive Copper DAC Cable. 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 an AOC. Passive copper cable with limited reach (typically ≤7m for high-speed gens).
  • NOT a transceiver. Fixed-length cable assembly; ends are not field-replaceable.
  • NOT a 1-to-1 cable. This is a splitter/breakout — both endpoints on the split side must accept the lower-speed downstream connector.
  • NOT bundled with adapters or transceivers — sold standalone.

Capabilities & Features

  • Passive copper twin-axial pairs — no power required, lowest latency.
  • DDM (Digital Diagnostic Monitoring) — temperature, voltage, optical power readable via I²C.
  • EEPROM on each end with product identification and operating data.
  • Hot-pluggable into any matching QSFP/SFP cage.

Compatibility & Constraints

  • Primary connector: QSFP-DD (compliant with MSA cage spec).
  • Reach: 3m fixed length.
  • Speed: 400GbE (split to 2x 50GbE).
  • Compatible adapters: ConnectX-7.
  • Compatible switches: NVIDIA Spectrum-4 SN5400 / Quantum-2 QM9700.
  • 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 two lower-speed endpoints.

Frequently Asked Questions (FAQ)

Q. What is the MCP7F80-W003?
The MCP7F80-W003 is a 3m passive copper hybrid cable: one 400GbE QSFP-DD head fans out to eight 50GbE legs.

Q. Does the switch need special configuration?
Yes. The head port must be configured for 8x50GbE breakout mode.

Q. Will T.E.S IT-SOLUTIONS confirm the configuration of MCP7F80-W003 before shipping?
Yes. T.E.S IT-SOLUTIONS (tes-itsolutions.com) inspects each unit and verifies vendor markings before dispatch from EU stock.
