InfiniBand/fibre optic cable Mellanox Technologies MCP1650-H002E26 2 m QSFP56 Black

The Mellanox Technologies MCP1650-H002E26 is a high-performance 2-meter passive copper cable designed for demanding data center and high-performance computing environments. Utilizing QSFP56 connectors, this cable supports 200Gb/s InfiniBand HDR connectivity, providing a reliable and efficient link between network devices. As a passive direct-attach copper (DAC) solution, it offers a cost-effective alternative to active optical cables for short-reach connections while maintaining signal integrity and performance.

Advantages

This cable is engineered to deliver robust connectivity for 200Gb/s systems without the need for external power, which helps in reducing overall power consumption within the rack. By eliminating the power requirements associated with active optical components, it contributes to a more energy-efficient infrastructure. Furthermore, the design minimizes electromagnetic interference (EMI) and undergoes rigorous testing during production to ensure consistent performance, durability, and a seamless installation experience right out of the box.

Suitable for

• High-performance computing clusters
• Data center top-of-rack switching
• Short-range server-to-switch connectivity
• InfiniBand HDR 200Gb/s network architectures

When it may not be suitable

This passive copper cable is intended for short-distance connections and will not function over long distances where signal attenuation becomes a factor. It is not suitable for environments requiring long-reach fiber optic cabling or applications that demand active signal amplification.

Key specifications

• Connector type: QSFP56 to QSFP56
• Cable length: 2 meters
• Data rate: 200Gb/s
• Cable type: Passive copper (DAC)
• Compatibility: InfiniBand HDR systems

How to use

To use the cable, simply insert the QSFP56 connector into the corresponding port on your network switch or server interface card. Ensure that the connector is fully seated until it clicks into place. Because this is a passive cable, no additional configuration or power supply is required. Handle the cable with care, ensuring that the minimum bend radius is respected to prevent damage to the internal copper conductors.

What to consider before purchase

• Verify that your hardware supports QSFP56 ports
• Confirm that the 2-meter length is sufficient for your rack layout
• Ensure the equipment is compatible with 200Gb/s InfiniBand standards

Usage recommendations

For optimal performance, avoid sharp bends or excessive tension on the cable during installation. Ensure that the cable is routed through proper cable management channels to maintain airflow and prevent physical stress on the connectors.
