BLUELAN Mellanox MCP7H50-H001R30 Cabo DAC breakout passivo compatível 200G QSFP-DD para 2x100G QSFP28, 3m

Aggregate 200 Gbps over twinaxial copper, split into two 100 Gbps QSFP28 links — this BLUELAN breakout DAC connects QSFP-DD ports to dual QSFP28 equipment for high-density rack and adjacent-rack interconnects.

Overview

Compatible with Mellanox MCP7H50-H001R30, this passive direct attach cable requires no signal conditioning and consumes less than 0.5W. The QSFP-DD connector on one end breaks out to two QSFP28 connectors on the other, enabling a single 200G port to feed two 100G ports. The 3-meter twinaxial copper construction is ideal for short-reach links within racks and across neighboring racks in data centers and HPC environments.

What stands out

• 200G to 2x100G breakout architecture
• Passive design: no power draw, no latency
• QSFP-DD to dual QSFP28 connectors
• 3-meter length for rack-to-rack links
• Hot-swappable for easy installation

Our verdict

A straightforward, low-power solution for splitting a 200G QSFP-DD port into two 100G QSFP28 links over short copper runs. The passive design keeps latency at zero and power draw negligible, while the 3-meter length covers most rack-to-rack scenarios.
