NVIDIA Mellanox MCP7H50-V001 200Gb/s QSFP56 Passive Copper Hybrid Splitter Cable, 1m: This is a 1-meter passive copper Direct Attach Cable (DAC) that splits one 200Gb/s QSFP56 port into two independent 100Gb/s QSFP56 connections. The V001 variant is fully passive and uses 30AWG conductors. There is no FEC retimer, no electronics, 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 1m, the thinner 30AWG conductors keep the cable lightweight and flexible, easing routing in dense in-rack deployments. The cable is passive: signal integrity at 1m is well within the no-equalization margin, and the cable adds no end-to-end latency beyond propagation delay. Power consumption is 0W.
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 in the same rack. ToR-to-server very-short-reach interconnects in HPC, AI training, and high-bandwidth storage clusters where the endpoints sit within 1m of the breakout port.
Technical Specifications
OEM: NVIDIA Mellanox
Part Number: MCP7H50-V001
Form Factor: QSFP56 to 2x QSFP56 (Y-splitter)
Data Rate: 200Gb/s split into 2x 100Gb/s
Cable Type: Passive Copper DAC (Hybrid Splitter)
Length: 1m (fixed)
Conductor Gauge: 30AWG
Power Draw: 0W (fully passive)
Condition: New — Factory-sealed
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 1m and cannot be extended; 30AWG defines the practical reach.
Frequently Asked Questions (FAQ)
Q. What is the MCP7H50-V001?
The MCP7H50-V001 is a 1m 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-V001 before shipping?
Yes. T.E.S IT-SOLUTIONS (tes-itsolutions.com) inspects each unit and verifies vendor markings before dispatch from EU stock.
