What data rates does the MCP7H00-G003 support?

The MCP7H00-G003 carries 100Gb/s aggregate (4x25Gb/s NRZ) on the single QSFP28 host side and splits it into two 50Gb/s (2x25Gb/s NRZ) links on the dual QSFP28 destination side. RS-FEC (CL91) is required by IEEE 802.3 for 50GbE link operation.

Can the MCP7H00-G003 be used as a 4x25G breakout to SFP28?

No. The MCP7H00-G003 is a 1x QSFP28 to 2x QSFP28 hybrid (100GbE to 2x50GbE) and does not break out into SFP28 connectors. For 100GbE QSFP28 to 4x25GbE SFP28 breakout you need a different cable family (e.g., MCP7F00-A series).

What does 'New' condition mean at T.E.S IT-SOLUTIONS?

MCP7H00-G003 units supplied by T.E.S IT-SOLUTIONS are new, factory-sealed cables. We verify all three connectors, lane integrity, and Y-junction condition before shipment. See https://www.tes-itsolutions.com for full warranty and return terms.

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.

Technical Specifications

OEM: NVIDIA Mellanox
Part Number: MCP7H00-G003
OEM Variant Code: MCP7H00-G003R26F
Form Factor: 1x QSFP28 to 2x QSFP28 (Hybrid Breakout)
Data Rate: 100GbE → 2x 50GbE (4x25Gb/s NRZ split 2+2)
Cable Type: Passive Copper Hybrid Breakout
Length: 3m
Cable Gauge: 26 AWG
Protocol: 100GbE / 50GbE Ethernet
Power Draw: Passive (0W)
Condition: New — Factory-sealed, distributed by T.E.S IT-SOLUTIONS

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.

Why Choose T.E.S IT-SOLUTIONS

T.E.S IT-SOLUTIONS verifies all three connectors, lane continuity, and Y-junction integrity on every hybrid cable before shipment. We provide expert consultation on 100GbE/50GbE breakout topologies, global shipping with 1–3 day handling, and dedicated post-sales support.
