NVIDIA Mellanox MCP7H60-W002R26 400GbE QSFP-DD to 2x 200GbE QSFP56 Passive Copper Splitter (DAC), 2m, 26AWG: This is a 2-meter passive copper Direct Attach Cable splitter for Ethernet, providing one 400GbE QSFP-DD input and two independent 200GbE QSFP56 outputs at 26AWG. This is a passive copper cable for Ethernet fabrics — it is NOT an InfiniBand NDR cable, NOT an active copper (ACC) cable, and NOT an AOC. The output connectors are QSFP56 only, not OSFP or QSFP28. This is a NEW unit.
Engineering Context
The MCP7H60-W002R26 splits a 400GbE port into two 200GbE links using PAM4 signaling at 50Gb/s per lane (4 lanes per output). Passive 26AWG construction provides 2m of reach without active electronics, keeping latency deterministic and power draw at 0W. The cable is intended for in-rack and adjacent-rack direct-attach use; the 26AWG gauge yields a manageable but still stiff assembly that should not be forced through tight bends or compact cable management arms.
Deployment & Use Cases
Splitting a 400GbE spine port into two 200GbE leaf uplinks in NVIDIA Spectrum Ethernet fabrics. Connecting a 400GbE switch port to two ConnectX-6 Dx 200GbE adapters in adjacent servers. In-rack top-of-rack to server breakout for high-density 200GbE compute. Cost-optimized 400G/200G fan-out at short reach.

Condition: NEW — Factory-sealed, supplied by T.E.S IT-SOLUTIONS
Compatibility & Hard Constraints
Compatible with NVIDIA Spectrum-3 (SN4000 series) 400GbE switches and ConnectX-6 / ConnectX-6 Dx 200GbE QSFP56 adapters. Requires switch ports configured for 2x 200GbE breakout mode. NOT compatible with InfiniBand NDR, OSFP, QSFP28 (100GbE), or QSFP-DD outputs — output legs are QSFP56 only. If you require longer reach, consider the W02AR26 (2.5m, 26AWG); the W002R26 is fixed at 2m and not field-terminable.
