NVIDIA Mellanox MCP7H50-V01A 200Gb/s QSFP56 Passive Copper Hybrid Splitter Cable, 1.5m: This is a 1.5-meter passive copper Direct Attach Cable (DAC) that splits one 200Gb/s QSFP56 port into two independent 100Gb/s QSFP56 connections. The V01A variant uses 30AWG conductors. There is no FEC retimer, no electronics, and no power draw. This is not a transceiver, not an Active Optical Cable, and not an active electrical cable. This is a new, factory-sealed unit.
Engineering Context
The MCP7H50 family bridges the HDR/200GbE generation to two HDR100 / 100GbE endpoints, doubling effective port density on the 200Gb/s side. The 200Gb/s QSFP56 end carries 4 lanes of 50Gb/s PAM4 signaling. Each 100Gb/s QSFP56 end carries 2 lanes of 50Gb/s PAM4 (HDR100). At 1.5m, the 30AWG conductors keep the cable lightweight and flexible while remaining within the no-equalization passive margin. The cable adds no end-to-end latency beyond propagation delay, draws 0W, and contains no diagnostic firmware.
Deployment & Use Cases
In-rack fan-out from a 200GbE Spectrum-2 / SN3700 switch port to two ConnectX-5 or ConnectX-6 100GbE adapter ports placed within a 1.5m radius. ToR-to-server short-reach interconnects in HPC, AI training, and high-bandwidth storage clusters where 1m is too short and 2m+ is unnecessary.

Compatibility & Hard Constraints
Designed for the NVIDIA Quantum HDR and Spectrum-2 family on the 200Gb/s end, paired with ConnectX-5 or ConnectX-6 adapters in HDR100 / 100GbE mode on the breakout ends. The 200Gb/s and 100Gb/s ends are not interchangeable. Not compatible with EDR-only ports that lack splitter support. Does not break out to SFP28 or QSFP28 form factors — both ends are QSFP56. Length is fixed at 1.5m and cannot be extended; 30AWG defines the practical reach for this passive variant.
Frequently Asked Questions (FAQ)
Q. What is the MCP7H50-V01A?
The MCP7H50-V01A is a 1.5m passive copper splitter DAC: one QSFP56 head at 200Gb/s breaks out into two legs at 100Gb/s each.
Q. Does the switch need special configuration?
Yes. The head port must be configured for breakout mode.
Q. Will T.E.S IT-SOLUTIONS confirm the configuration of MCP7H50-V01A before shipping?
Yes. T.E.S IT-SOLUTIONS (tes-itsolutions.com) inspects each unit and verifies vendor markings before dispatch from EU stock.
