NVIDIA Mellanox MCP2M00-A001E30N 25GbE SFP28 Passive Copper Cable, 1m, 30AWG: This is a 1-meter passive copper Direct Attach Cable (DAC) engineered for 25Gb/s Ethernet (25GbE) point-to-point interconnects. The cable uses 30AWG twinaxial copper terminated in fixed SFP28 connectors. This is a passive cable; it is NOT an active copper cable or an AOC and contains no signal-conditioning electronics. This is a new unit.
Engineering Context
The MCP2M00-A001E30N delivers cost-effective 25GbE connectivity at short reach. Passive copper cables consume essentially zero port power because there are no transceiver driver electronics. The 30AWG conductor balances flexibility against electrical reach at the 1-meter length point. Latency is limited to copper propagation, with no electrical-to-optical conversion overhead. Cables are SFF-8472 compliant for I2C management and EEPROM readout. BER targets follow IEEE 802.3by for 25GbE links.
Deployment & Use Cases
Top-of-Rack switch to server uplinks within a single rack. ConnectX-4 Lx, ConnectX-5, or ConnectX-6 Dx EN adapter to Spectrum SN2000-series switch within 1 meter. Hyperconverged infrastructure (HCI) node interconnects. Storage server cabling where a passive copper solution is preferred over AOC for cost and power.
