Network Cable BlueLAN MCP1650-H003E30 QSFP56 200GBASE-CR4 30AWG 3 Meter

The BlueLAN MCP1650-H003E30 QSFP56 200GBASE-CR4 direct attach cable is a 3 meter, 30AWG high-speed copper interconnect designed for short-reach data center links. Engineered for 200GBASE-CR4 applications, this cable supports quad-lane 56Gbps electrical interfaces in a compact QSFP56 form factor to deliver reliable, low-latency connections between switches, routers and servers. Its fixed-length assembly and robust connectors simplify rack-to-rack and top-of-rack deployments while maintaining signal integrity for high-throughput environments.

Advantages

The cable offers low insertion loss and consistent impedance matching across all lanes to minimize bit error rates and latency in high-density installations. Its 30AWG conductors and quality shielding provide a balance of flexibility and durability for repeated handling during installation and maintenance. The QSFP56 connector design ensures compatibility with 200GBASE-CR4 ports, enabling direct, power-efficient links without the need for optical transceivers.

Suitable for

• Short-reach rack-to-rack and switch-to-server connections in data centers
• High-performance computing clusters and storage networks requiring 200G links
• Top-of-rack switch uplinks and spine-leaf fabric interconnects

Key specifications

• Data rate: compatible with 200GBASE-CR4
• Connector type: QSFP56 to QSFP56
• Length: 3 meters
• Wire gauge: 30AWG
• Number of lanes: 4 electrical lanes (quad-lane)
• Transmission medium: shielded copper direct attach cable

How to use

Insert each QSFP56 connector firmly into the respective port until it latches. Ensure both ends are connected to compatible 200GBASE-CR4 QSFP56 ports and that cable routing avoids sharp bends or compression points. For hot-plug operations, verify device compatibility with direct attach copper cables and follow system vendor guidance for link negotiation and port configuration. If a port does not detect the link, reseat the connector and inspect for contamination or deformation on the connector interface.

Usage recommendations

Route the cable with gentle curves and maintain the manufacturer’s minimum bend radius to preserve signal integrity. Use this direct attach cable for short-reach connections where optical transceivers are not required, and verify switch firmware and port settings for 200GBASE-CR4 operation before deployment.
