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. Active optical cable using VCSEL multi-mode fiber technology with integrated optics on each end — reaches longer distances than DAC.
NOT a transceiver. Fixed-length cable assembly; the optics are integrated and cannot be removed or replaced.
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

VCSEL multi-mode optical engine, 850 nm.
Active retiming on each end for clean signal regeneration.
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).
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 two lower-speed endpoints.
