What data rates does the MCP7H00-G02A support?

The MCP7H00-G02A carries 100Gb/s aggregate (4x25Gb/s NRZ) on the host QSFP28 side and splits it into two 50Gb/s (2x25Gb/s NRZ) links on the dual QSFP28 destination side. RS-FEC (Clause 91) is required by IEEE 802.3 for 50GbE link operation.

Can the MCP7H00-G02A break out into SFP28 ports?

No. The MCP7H00-G02A is a QSFP28-to-2xQSFP28 hybrid (100GbE to 2x50GbE). It has no SFP28 connectors and cannot be used for 4x25GbE breakout. For QSFP28 to 4xSFP28 breakout, the MCP7F00 series is required.

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

MCP7H00-G02A 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-G02A 100GbE to 2x50GbE Passive Copper Hybrid Breakout Cable, 2.5m: This is a 2.5-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. 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-G02A is a passive copper assembly carrying 100Gb/s aggregate (4x25Gb/s NRZ) on the host side, split into two 50GbE (2x25Gb/s NRZ) lanes on the destination side. Hybrid breakout enables port-density consolidation when a 100GbE switch port is over-provisioned for the endpoint. The 2.5m length sits well within the reliable passive copper window for 25G NRZ. The cable is fully passive with zero power draw; link partners must negotiate and apply RS-FEC (CL91) per IEEE 802.3 for 50GbE operation.

Deployment & Use Cases

Connecting a 100GbE QSFP28 port on an NVIDIA Spectrum SN2700 or SN3700 to two 50GbE-capable endpoints (ConnectX-5 EN, ConnectX-6 Dx) in adjacent racks or within the same rack. Aggregation of two 50GbE storage or compute servers onto one switch port. HPC fan-out where pairs of compute nodes share an upstream 100GbE port.

Technical Specifications

OEM: NVIDIA Mellanox
Part Number: MCP7H00-G02A
NVIDIA OEM Code: 980-9I990-00C02A
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: 2.5m
Protocol: 100GbE / 50GbE Ethernet

Compatibility & Hard Constraints

Compatible with NVIDIA Spectrum SN2700, SN3700, and equivalent 100GbE QSFP28 switches that support 50GbE breakout. Compatible with ConnectX-5 EN and ConnectX-6 Dx in 50GbE single-lane mode (2x25G NRZ). The 100GbE port must be explicitly configured for breakout in switch software. Not compatible with switches lacking 50GbE breakout firmware. Not compatible with 200GbE PAM4 endpoints. Not compatible with QSFP+ 40GbE-only ports. Not a transceiver-and-patch-cord assembly; the 2.5m length and Y topology are fixed.
