Identity
The NVIDIA Mellanox® MCP7F00-A001 is a QSFP28 100GbE 1m Passive Copper DAC Cable. This is a splitter / breakout cable assembly. New, factory-sealed 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: QSFP28 (compliant with MSA cage spec).
Reach: 1m fixed length.
Speed: 100GbE (split to 2x 25GbE).
Compatible adapters: ConnectX-4 / ConnectX-5 / ConnectX-6.
Compatible switches: NVIDIA Spectrum / Spectrum-2 / Switch-IB 2.
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 MCP7F00-A001?
The MCP7F00-A001 is a 1m passive copper breakout cable: one QSFP28 head at 100GbE breaks out into four SFP28 legs at 25GbE each.
Q. Does the switch need special configuration?
Yes. The head port must be configured for 4x25GbE breakout mode.
Q. Will T.E.S IT-SOLUTIONS confirm the configuration of MCP7F00-A001 before shipping?
Yes. T.E.S IT-SOLUTIONS (tes-itsolutions.com) bench-tests each unit where test topology is available, 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.
