NVIDIA Mellanox MC2206130-00A 40Gb/s QSFP+ Passive Copper DAC, 0.5m: This is a 0.5-meter passive copper Direct-Attach Cable (DAC) terminated with QSFP+ connectors on both ends. The cable supports 40Gb/s data rate (QDR/FDR10 InfiniBand or 40Gb Ethernet) and uses 30 AWG copper conductors. It is a VPI-capable interconnect for short rack-internal links. This is a passive cable, not active — no powered electronics inside. This is a refurbished unit, sold as a lot of 10.
Engineering Context
The MC2206130-00A is engineered for rack-internal Top-of-Rack to first-hop server runs where 0.5m reach is sufficient. As a passive DAC, it draws no port power, runs at near-zero latency (no DSP), and offers cost-effective 40Gb/s connectivity. The 30 AWG conductor gauge is optimized for short reach with full 40Gb/s signal integrity. VPI support allows the same cable to be used for InfiniBand QDR/FDR10 or 40Gb Ethernet on Mellanox Virtual Protocol Interconnect-capable adapters and switches.
Deployment & Use Cases
Server-to-ToR switch links inside a single rack at 40Gb/s. Adjacent-rack inter-switch links where reach is under 1m. InfiniBand QDR/FDR10 fabrics on Mellanox SX6000 series switches. Cost-sensitive 40GbE deployments where short reach allows passive copper instead of optics.

Compatibility & Hard Constraints
Compatible with Mellanox SX6000-series QDR/FDR10 InfiniBand switches, Mellanox 40GbE switches, and ConnectX-2/ConnectX-3 VPI adapters. Both ends require QSFP+ ports configured for 40Gb/s. This is a passive cable — not compatible with ports that require active optical signaling for distance. Maximum reach is fixed at 0.5m. Not suitable for 56Gb/s FDR (which requires FDR-rated DACs or AOCs). Not a breakout cable; QSFP+ to QSFP+ point-to-point only.
