NVIDIA Mellanox MCP2M00-A002 25GbE SFP28 Passive Direct-Attach Copper Cable, 2m, 30 AWG: This is a 2-meter passive direct-attach copper (DAC) cable for 25Gb/s Ethernet (25GbE) point-to-point links between SFP28 ports. It is a fixed-length integrated assembly with bonded SFP28 connectors on both ends, not a transceiver-and-patch-cable pair. The cable uses 30 AWG twin-axial copper conductors and requires no port power. This unit is brand new.
Engineering Context
The MCP2M00-A002 delivers low-latency, zero-power 25GbE connectivity in a fully shielded copper assembly. 30 AWG conductors are sized for short intra-rack reaches; the cable is fully shielded for EMI integrity in dense rack environments. Signal integrity at 25 Gb/s NRZ depends on host SFP28 port FEC settings; both ends must agree on FEC mode. Insertion loss budget for the assembly is fixed at the factory and cannot be re-terminated in the field.
Deployment & Use Cases
Top-of-Rack switch to server NIC connections within a single rack at 25GbE. SFP28 host adapter to switch port short-reach links. Storage node uplinks where ports are SFP28-native and the run is under 2m.
