CBO QSFP Direct-Attach Cable MC2210130-001-BL 1 m, QSFP+ Male to Male, 40 Gbit/s

The CBO QSFP Direct-Attach Cable MC2210130-001-BL is a 1 m copper twinax assembly with QSFP+ male connectors on both ends, supporting 40 Gbit/s link speed for short-range, high-throughput connections. Engineered for direct interconnection of compatible QSFP ports in switches, servers and other network equipment, this 1 metre cable delivers low-latency, high-bandwidth performance suitable for top-of-rack and data centre interconnects. The BlueOptics branded cable follows common QSFP+ electrical pinouts and physical dimensions to ensure compatibility with standard QSFP interfaces.

Advantages

The direct-attach twinax design offers lower cost and power consumption compared with active optical solutions for short distances while maintaining 40 Gbit/s throughput. A one-metre length minimises excess cabling in dense rack environments and reduces signal attenuation associated with longer copper runs. The QSFP+ male-to-male connectors provide a straightforward plug-and-play connection between QSFP ports without the need for transceivers or additional modules.

Suitable for

• Top-of-rack switch-to-switch connections within a rack
• Server-to-switch uplinks in data centre racks
• Interconnects between line cards, patch panels and aggregation switches
• Short-reach, high-bandwidth cluster and compute node links

Key specifications

• Connector type: QSFP+ male to QSFP+ male
• Length: 1 metre
• Maximum data rate: 40 Gbit/s
• Cable type: Passive copper twinax
• Latency: low, suitable for short-range low-latency links
• Typical application: short-range data centre interconnects and top-of-rack cabling

How to use

Verify that both endpoints support QSFP+ direct-attach copper connections and that the network equipment firmware allows passive copper cables. With devices powered down if recommended by the vendor, align and insert each QSFP+ connector into the corresponding QSFP port until the latch engages. After powering the equipment, monitor link status and performance counters to confirm a stable 40 Gbit/s link. For hot-plug support, follow the server or switch vendor guidelines to avoid link negotiation issues.

Usage recommendations

Avoid tight bends and kinks in the cable; maintain the manufacturer’s minimum bend radius to preserve signal integrity. Use the 1 m length to minimise cable slack in dense racks and route the cable to prevent interference with airflow. For environments requiring longer reach or optical isolation, consider optical transceivers and fibre cabling instead of copper direct-attach solutions.
