Identity
The NVIDIA Mellanox® MCP7Y50-N01A is a OSFP 800GbE 1.5m 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: OSFP (compliant with MSA cage spec).
- Downstream connectors: 2 × OSFP on the split side.
- Reach: 1.5m fixed length.
- Speed: 800GbE.
- Compatible adapters: ConnectX-8.
- Compatible switches: NVIDIA Spectrum-4 SN5400 / Quantum-3.
- 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 MCP7Y50-N01A?
The MCP7Y50-N01A is a 1.5m passive copper splitter DAC: one OSFP head at NDR 800Gb/s breaks out into four OSFP legs at 200Gb/s each.
Q. Does the switch need special configuration?
Yes. The head port must be configured for 4x200G breakout mode.
Q. Will T.E.S IT-SOLUTIONS confirm the configuration of MCP7Y50-N01A 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.
