Identity
The NVIDIA Mellanox® MCP1660-W001 is a QSFP-DD 400GbE 1m Passive Copper DAC Cable. 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 splitter or breakout cable. 1-to-1 cable assembly only.
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: 1m fixed length.
Speed: 400GbE.
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.
