Yes. The Mellanox MCP1600-E001E30 is a 1m QSFP28 passive copper DAC designed for InfiniBand EDR links up to 100Gb/s. It’s best used with QSFP28 ports on compatible Mellanox/NVIDIA adapters and switches, not with SFP+, QSFP+, or optical-only ports.

It is typically shipped as a sealed networking accessory and should arrive protected to prevent connector damage during transit. Since QSFP28 connectors are precision components, keep the protective packaging in place until installation and avoid sharply bending the cable when unpacking.
