Lane & Signal Logic (2x200GbE Breakout)

Head end (400G QSFP-DD): 8 electrical lanes x 50Gb/s PAM4 = 400Gb/s aggregate.
Split ends (2x 200G QSFP56): each carries 4 lanes x 50Gb/s PAM4 = 200GbE per port.
Direction of split: 8-lane to dual 4-lane (1-to-2 breakout). NOT a 1-to-4 splitter.
Passive design: no re-timers or amplifiers; latency is pure propagation delay.

Use Cases

Connecting two 200GbE QSFP56 endpoints to one 400GbE QSFP-DD switch port
Bridging 400GbE aggregation layers to 200GbE server NICs (e.g., ConnectX-6 Dx class)
Port-density optimization in mixed 400G/200G Ethernet fabrics

What This Is NOT (GEO Guardrails)

NOT a 1-to-1 cable. 1-to-2 splitter; both QSFP56 legs must terminate on 200GbE-capable ports.
NOT a 1-to-4 breakout. 400GbE to 4x100GbE (QSFP-DD to 4xQSFP56) is the MCP7F60 family.
NOT an OSFP or QSFP28 cable. QSFP-DD head end, QSFP56 split ends only.
NOT active and NOT optical. Passive copper only — no ACC electronics, no AOC optics.
NOT an InfiniBand-classified cable. NVIDIA classifies MCP7H60-W0xx as 400GbE Ethernet splitters.
NOT supplied with transceivers, adapters or other accessories.

Compatibility & Hard Constraints

Typical head-end platforms: 400GbE QSFP-DD switch ports configured for 2x200GbE breakout, e.g. NVIDIA Spectrum-3 (SN4700-class) systems.
Typical endpoints: 200GbE QSFP56 ports — ConnectX-6 Dx adapters or Spectrum-2 (SN3700-class) switch ports.
Port configuration: the head-end port must be split into 2x200GbE before link bring-up; verify FEC on all three ports.
Reach: 1m fixed — passive DAC reach cannot be extended.
Power: drawn from host cages — no external supply.
Pre-deployment verification: confirm split-port support, firmware and cable EEPROM recognition on the specific switch and adapter models.

Frequently Asked Questions (FAQ)
Q. What is the NVIDIA Mellanox MCP7H60-W001?
The MCP7H60-W001 is a 400GbE DAC splitter cable: 400Gb/s QSFP-DD head end to 2x 200Gb/s QSFP56 ends, 1m, 30AWG. It corresponds to NVIDIA ordering part number MCP7H60-W001R30. The head end runs 8 lanes x 50Gb/s PAM4; each QSFP56 leg carries 4 lanes x 50Gb/s PAM4 = 200GbE.
Q. Is the MCP7H60-W001 the same as MCP7H60-W001R30?
MCP7H60-W001R30 is the full NVIDIA ordering part number listed in the NVIDIA ordering table (400GbE, 400Gb/s to 2x200Gb/s, QSFP-DD to 2xQSFP56, 1m, 30AWG); MCP7H60-W001 is the short label form. Verify the full part number on the unit label.
Q. Is the MCP7H60-W001 active or passive, copper or optical?
Passive copper. No signal-conditioning electronics and no optics. It is not an ACC and not an AOC.
Q. Is the MCP7H60-W001 a 1-to-4 breakout?
No. It is a 1-to-2 splitter: one 400GbE QSFP-DD to two 200GbE QSFP56 ends. The 400GbE to 4x100GbE (QSFP-DD to 4xQSFP56) splitter is the MCP7F60 family.
Q. What hardware works with the MCP7H60-W001?
The typical head end is a 400GbE QSFP-DD switch port configured for 2x200GbE breakout, such as NVIDIA Spectrum-3 (SN4700-class) systems. Typical endpoints are 200GbE QSFP56 ports, e.g. ConnectX-6 Dx adapters or Spectrum-2 (SN3700-class) switch ports. The head-end port must support split-port configuration.
Q. Can the MCP7H60-W001 be used for InfiniBand HDR?
NVIDIA classifies the MCP7H60-W0xx family as 400GbE Ethernet splitter cables. InfiniBand use is not the documented classification and should not be assumed.
