Mellanox Technologies MCP1600-C002 2m 100Gb/s passive copper QSFP network ethernet cable

Direct-attach 100 Gb/s link for QSFP ports

This two-metre passive copper cable carries 100 Gb/s Ethernet between QSFP ports without any external power supply. It is built for data-centre racks and high-performance clusters where short, low-latency links are needed between switches, routers, servers or storage arrays. The assembly complies with the SFF-8436 specification and meets RoHS requirements.

Steady throughput without active components

Because the cable is passive, it draws no power and adds no active circuitry to the signal path, so latency and power draw stay constant regardless of how long the link runs at line rate. The 12.50 GB/s per lane design sustains full 100 Gb/s throughput across the 6.56 ft length without the heat or EMI associated with active optical or active copper alternatives. Signal integrity is maintained by the cable construction itself rather than by onboard equalisation.

Verify QSFP port spacing and cable routing

Confirm that both endpoints present QSFP connectors compliant with IEEE 802.3 bj and that the two-metre reach matches the physical distance between them, allowing enough slack for cable management without sharp bends. Ensure the rack or chassis airflow path can accommodate the cable diameter and that no active gear requiring powered cables is in the link budget.
