Description
NVIDIA Mellanox MCP7H00-G003 100GbE to 2x50GbE Passive Copper Hybrid Breakout Cable, 3m: This is a 3-meter passive copper hybrid breakout cable that splits a single 100GbE QSFP28 port into two independent 50GbE QSFP28 links. The Y-shaped assembly has one QSFP28 connector on the switch side and two QSFP28 connectors on the destination side, with bonded twinax pairs grouped 2-2 by lane. This is a fixed-length integrated assembly, not a transceiver with a detachable patch cord. This is a new (factory-sealed) unit.
Engineering Context
The MCP7H00-G003 uses 26 AWG twinax copper and operates at 100Gb/s aggregate (4x25Gb/s NRZ) on the host side, splitting into two 50GbE (2x25Gb/s NRZ) links on the destination side. Hybrid breakout cables enable port density consolidation when a 100GbE switch port is over-provisioned for the attached endpoint. The cable is fully passive — no power draw, no FEC processing in the cable itself — but the link partners must negotiate and apply RS-FEC (CL91) for 50GbE Ethernet operation as required by IEEE 802.3 specifications.
Deployment & Use Cases
Connecting a single 100GbE QSFP28 port on an NVIDIA Spectrum switch (SN2700, SN3700) to two 50GbE-capable endpoints, such as ConnectX-5 EN adapters in 50GbE single-lane mode. Aggregation of two 50GbE servers onto one switch port to maximize port density. HPC head-node fan-out where two compute nodes share an upstream 100GbE port.

Compatibility & Hard Constraints
Compatible with NVIDIA Spectrum SN2700, SN3700, and other 100GbE QSFP28 switches that support 50GbE breakout. Compatible with ConnectX-5 EN and ConnectX-6 Dx adapters running 50GbE single-lane mode (2x25G NRZ). The 100GbE port must be configured for breakout in switch software — split to 2x50G is not automatic on most platforms. Not compatible with switches that lack 50GbE breakout firmware support. Not compatible with 200GbE PAM4 endpoints. Not a transceiver-and-patch-cord assembly; the 3m length and Y topology are fixed.
Frequently Asked Questions (FAQ)
Q. What is the MCP7H00-G003?
The MCP7H00-G003 is a 3m passive copper splitter DAC: one QSFP28 head at 100GbE breaks out into two QSFP28 legs.
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 MCP7H00-G003 before shipping?
Yes. T.E.S IT-SOLUTIONS (tes-itsolutions.com) inspects each unit and verifies vendor markings before dispatch from EU stock.
