Cabo de ligação direta Mellanox LinkX 200GBase QSFP56 para QSFP56 1m LSZH preto

High-density data centers and HPC clusters often struggle to balance port density, power consumption, and signal integrity at 200 Gb/s. The Mellanox LinkX MCP1650-H001E30 direct attach copper cable solves this by delivering a compact, low-latency link that plugs directly into QSFP56 ports without the cost and complexity of optical transceivers. This 1-meter passive DAC is ideal for top-of-rack to server, storage, or switch connections where short reach and high bandwidth are critical.

Who is it for

Network architects, data center operators, and system integrators deploying 200GbE Ethernet or HDR InfiniBand fabrics. It suits hyperscale, enterprise, and cloud environments that need reliable, hot-pluggable interconnects with minimal power draw and no active electronics.

Main features

• 200 Gb/s aggregate throughput with QSFP56 connectors on both ends
• Passive copper design: less than 0.5 W per end, no external power required
• 30 AWG twinax cable with LSZH jacket for low smoke and zero halogen in fire conditions
• Hot-pluggable and IEEE 802.3cd compliant for broad switch and adapter compatibility
• Supports both Ethernet and InfiniBand protocols for converged fabrics
• Black jacket blends into high-density cabling and simplifies port identification

Tips

For best performance, keep bend radius above the minimum specified by the manufacturer and avoid sharp twists near the connector. Use this DAC for distances up to 3 meters in high-airflow racks; for longer runs, consider active optical cables. Always verify QSFP56 port compatibility with your Mellanox/NVIDIA switch or adapter before installation.
