BlueLAN MCP7F60-W002R26-BL NVIDIA Compatible 400G QSFP-DD to 4x QSFP56 DAC Breakout Cable 2m AWG26

400 Gbps aggregate throughput over a 2-meter direct attach copper breakout cable, built for NVIDIA environments where density and signal integrity are non-negotiable.

Overview

The BlueLAN MCP7F60-W002R26-BL is a passive QSFP-DD to 4x QSFP56 DAC breakout cable. It connects a single 400G QSFP-DD port to four independent 100G QSFP56 ports, enabling flexible top-of-rack and spine-leaf architectures. AWG26 copper conductors keep the cable thin and manageable while maintaining 100 Ohm impedance for reliable Ethernet signaling.

What stands out

• Aggregate data rate: 400 Gbps
• Breakout configuration: 1x QSFP-DD to 4x QSFP56
• Passive design: no power draw beyond the 3.3V host supply
• Hot-pluggable for zero-downtime maintenance
• Operating range 0°C to 70°C, storage -40°C to 85°C
