Description

NVIDIA Mellanox MC2207130-00A 56Gb/s QSFP+ Passive Copper DAC, 0.5m: This is a 0.5-meter passive direct attach copper (DAC) cable terminated with QSFP+ connectors on both ends, rated for 56Gb/s FDR InfiniBand and 56GbE. As a passive cable, it has no active electronics or power draw. This is a new unit.

Engineering Context

The MC2207130-00A is a Twinax assembly built for ultra-short intra-rack links: switch-to-server, switch-to-switch in adjacent units, or top-of-rack to server NIC where the cable run is under one meter. Passive DACs have the lowest latency option in the QSFP+ family and zero added power versus optics. At 56Gb/s the four lanes run 14Gb/s NRZ each (FDR class).

Deployment & Use Cases

FDR InfiniBand intra-rack links in HPC clusters. 56GbE Ethernet ToR-to-server connections (Mellanox proprietary 56GbE). Backwards-compatible 40Gb/s QSFP+ (40GbE / 40G QDR IB) on host ports that negotiate down. Stacking adjacent switches in 1U gaps.

Compatibility & Hard Constraints

Compatible with NVIDIA Mellanox SwitchX/SwitchX-2 and Switch-IB switches, and ConnectX-3/ConnectX-3 Pro VPI adapters with QSFP+ ports. Not a QSFP28/QSFP56 cable; will not negotiate 100Gb/s or 200Gb/s rates. Not a breakout cable. Fixed 0.5m length — too short for non-adjacent racks. Verify port FEC and rate settings on third-party switches before deployment, as 56Gb/s is a Mellanox-specific QSFP+ extension and may not be supported by other vendors.
