Network Cable Mellanox MCP1650-H000.5E30 QSFP56 200GBASE-CR4 0.5m Blue

The Mellanox MCP1650-H000.5E30 QSFP56 200GBASE-CR4 0.5m direct attach network cable is a short-reach copper interconnect intended for high-density data center environments. With a QSFP56 connector and 200GBASE-CR4 signaling, this 0.5 metre cable supports multi-lane 200 Gbps links between switches, network interface cards and other QSFP56 ports. The 30 AWG conductor construction balances flexibility and mechanical durability while maintaining signal integrity and low latency for high-throughput applications.

Advantages

This cable provides a compact, cost-effective alternative to optical modules for short-distance, high-bandwidth connections. The QSFP56 form factor delivers four electrical lanes aggregated to 200 Gbps, enabling straightforward deployment in top-of-rack and spine switch scenarios. Its short length and flexible 30 AWG construction reduce cable management clutter and allow tight bend routing in dense racks. The blue jacket offers visual identification for easy tracing during installation and maintenance.

Suitable for

• Short-reach 200 Gbps uplinks between switches and servers
• Direct attach connections in top-of-rack and spine-and-leaf architectures
• High-throughput compute clusters and Infiniband environments
• Patch connections inside network equipment cabinets where optical transceivers are not required

Key specifications

• Connector type: QSFP56 to QSFP56
• Data rate: 200 Gbps (200GBASE-CR4)
• Length: 0.5 m
• Conductor gauge: 30 AWG
• Cable jacket color: blue
• Transmission medium: copper direct attach
• Use case: short-reach, high-density interconnects

How to use

Insert each QSFP56 connector into compatible QSFP56 ports on network switches or adapter cards until the connector latch engages. Ensure both endpoints support 200GBASE-CR4 electrical signaling and are configured for the required link aggregation settings. Route the cable to avoid sharp bends and maintain recommended bend radius for 30 AWG construction. For best performance, keep the cable within the specified rack and cabinet airflow paths to prevent thermal stress.

Usage recommendations

Verify compatibility with the host devices and firmware release before deployment. Use this direct attach copper cable for short links up to 0.5 m; for longer distances or optical isolation, consider fiber-optic transceivers. Inspect connectors for debris and damage prior to insertion and follow ESD precautions when handling.
