DAC cable CBO AX-F0110-3Q1CU5M 10m QSFP direct-attach copper

The DAC cable CBO AX-F0110-3Q1CU5M 10m QSFP direct-attach copper is a 10-metre passive twinax copper cable engineered for QSFP ports and short-reach 40/100 Gbps links. It provides a single-cable wired connection between compatible switches, servers and other networking equipment, offering lower power consumption and reduced latency compared with optical transceivers. The cable is intended for use in data centres and rack-to-rack interconnects where a robust 10 m QSFP copper connection is required.

Advantages

This QSFP direct-attach copper cable delivers reliable high-speed connectivity with low insertion loss and consistent signal integrity over 10 metres. As a passive twinax solution, it eliminates the need for separate transceivers, which reduces both hardware costs and power draw. The cable is plug-and-play compatible with QSFP ports on supported equipment, simplifying deployment. Its copper construction offers predictable latency and thermal behaviour compared with active optical alternatives.

Suitable for

• Short-reach 40/100 Gbps links between switches and servers
• Top-of-rack and rack-to-rack connections in data centres
• High-density switch fabrics and aggregation layers
• Environments where power efficiency and low latency are priorities

Key specifications

• Cable type: Passive twinax copper (direct-attach cable)
• Connector type: QSFP-compatible ends
• Length: 10 metres
• Data rates: Compatible with high-speed QSFP links (40/100 Gbps class)
• Use case: Short-reach interconnects within racks and between nearby racks
• Construction: Shielded copper pairs for reduced electromagnetic interference

How to use

Insert the QSFP-compatible connector ends into the corresponding QSFP ports on each device until the connector latch engages. Ensure both devices are powered down or follow hot-swap guidance from the device manufacturer if supported. Verify link indicators on connected equipment and check system configuration for the desired port speed and mode. For proper performance, avoid tight bends and maintain recommended bend radius for copper twinax cables.

Recommendations

Install the cable within the same rack or between adjacent racks to stay within short-reach design parameters. Route the cable away from high-power or noisy electrical sources, secure it to prevent strain on connectors, and follow equipment vendor compatibility lists to ensure proper link negotiation and full performance.
