Description
NVIDIA Mellanox MCP7F00-A02A QSFP28 to 4xSFP28 100GbE Hybrid Breakout DAC, 2.5m, 30 AWG: This is a 2.5-meter passive copper hybrid breakout cable that splits a single QSFP28 100GbE port into four independent SFP28 25GbE links. NVIDIA P/N 980-9I48P-00C02A. This is a passive Direct Attach Copper assembly with no electronics, retimers, or DSPs. This is NOT an active optical cable, NOT a 1:1 QSFP28 cable, and NOT a fiber optic transceiver. Condition: Refurbished — tested by T.E.S IT-SOLUTIONS.
Engineering Context
The MCP7F00-A02A is built on 30 AWG twinax conductors and operates as a pure electrical signal path. Aggregated bandwidth is 100Gb/s, lane structure is 4x25Gb/s NRZ, with each SFP28 leg presenting a single 25Gb/s lane. Power consumption is 0W on the cable itself; only the host ports draw power. Latency is bounded by physical propagation only — typically a few nanoseconds per meter — with no protocol-layer processing introduced by the cable.
Deployment & Use Cases
Top-of-Rack QSFP28 switch ports fanned out to four 25GbE servers, NICs, or storage targets. Spectrum SN2000/SN3000 switch port density expansion onto ConnectX-4 Lx, ConnectX-5 EN, or ConnectX-6 Dx 25GbE adapters. Storage front-end aggregation for SAN and NAS controllers using SFP28 ports. Enterprise leaf-spine fabrics consolidating 25GbE endpoints into a 100GbE uplink trunk.

Compatibility & Hard Constraints
Compatible with NVIDIA Mellanox Spectrum Ethernet switches with QSFP28 ports configured for 4x25GbE breakout, and with ConnectX-4 Lx, ConnectX-5, and ConnectX-6 Dx adapters supporting SFP28 25GbE. The QSFP28 host port must be explicitly configured for breakout / fan-out mode; the cable cannot force this on its own. Not for 1:1 QSFP28-to-QSFP28 100GbE links. Not an InfiniBand cable. Not for 200GbE, 400GbE, or 50G PAM4 lanes. Fixed 2.5m length, no spooling possible.
