NVIDIA Mellanox MC2206128-005 QSFP Passive Copper Cable, 5m, FDR10/40GbE VPI — Lot of 3: This listing is a lot of three (3) passive copper Direct Attach Cables (DACs) with QSFP-to-QSFP connectors, each 5 meters in length. The cable is a VPI (Virtual Protocol Interconnect) interconnect rated for InfiniBand FDR10 (40Gb/s) and 40 Gigabit Ethernet. This is a passive cable with no signal conditioning electronics; it is not an active copper cable and not a fiber optic AOC. These are refurbished units.
Engineering Context
The MC2206128-005 uses copper conductors to carry four lanes of 10Gb/s NRZ signaling (4x10Gb/s = 40Gb/s aggregate) for FDR10 InfiniBand or 40GbE Ethernet operation. As a passive cable, it draws no power from the host and contributes negligible added latency relative to the SerDes. The 5-meter length suits top-of-rack to mid-row reach within a single cabinet row. The QSFP form factor is the legacy QSFP+ pinout, not QSFP28 — link rate is capped at the FDR10/40GbE level.
Deployment & Use Cases
Connecting Mellanox SX6000-series InfiniBand FDR10 switches to legacy ConnectX-2 and ConnectX-3 host adapters. 40GbE top-of-rack to aggregation links in legacy data center fabrics. HPC cluster builds where FDR10 (not FDR or EDR) is the chosen InfiniBand generation. Cost-effective bulk cabling for storage backend networks at 40Gb/s.

Condition: Refurbished — Tested by T.E.S IT-SOLUTIONS
Compatibility & Hard Constraints
Compatible with Mellanox QSFP+ ports on SwitchX-2 SX6000-series switches and ConnectX-2 / ConnectX-3 / ConnectX-3 Pro adapters operating in FDR10 or 40GbE mode. Not rated for FDR (56Gb/s) — link will negotiate down or fail link training on FDR-only ports. Not compatible with QSFP28 EDR or 100GbE-only ports unless the host explicitly supports backward QSFP+ negotiation. Not a breakout cable; QSFP-to-QSFP only. Fixed 5-meter length.
