CBO DAC SFP+ cable SFP-10G-DAC-0.5M 10G 0.5 m twinax direct-attach

CBO DAC SFP+ cable SFP-10G-DAC-0.5M 10G 0.5 m twinax direct-attach is a fixed-length twinax copper cable with integrated SFP+ connectors designed for short-reach 10 Gigabit Ethernet links. The cable provides a direct-attach connection between SFP+ ports on switches, servers or storage devices, delivering low latency and deterministic performance without the need for separate transceivers or optical modules. Its 0.5 m length is suited to rack-level interconnects and top-of-rack deployments where short, reliable connections are required.

Advantages

The direct-attach twinax design offers lower power consumption and reduced latency compared with active optical solutions, while maintaining a simple plug-and-play installation. Integrated SFP+ connectors eliminate the need to purchase and install separate modules, reducing component count and simplifying inventory. The fixed 0.5 m length ensures predictable cable management and minimizes signal degradation for short-distance links in dense rack environments.

Suitable for

• Connecting SFP+ ports between top-of-rack switches and servers
• High-density rack-level interconnects in data centers
• Short-reach links between storage arrays and host adapters
• Environments where low latency and low power are priorities

Key specifications

• Interface: SFP+ to SFP+ direct-attach twinax cable
• Data rate: 10 Gigabit Ethernet
• Length: 0.5 m fixed
• Cable type: Passive twinax copper
• Form factor: Plug-and-play SFP+ connectors
• Use case: Short-reach rack-level connections

How to use

Install the cable by plugging each integrated SFP+ connector into the SFP+ port of the devices to be linked, ensuring latch mechanisms engage fully. No additional configuration or optical transceivers are required; the connected devices will negotiate link parameters automatically according to their SFP+ port capabilities. Route the cable within the rack to avoid sharp bends and maintain proper airflow around equipment.

Usage recommendations

For reliable operation, use this 0.5 m twinax DAC for connections within the same rack or adjacent racks, avoid exceeding the minimum bend radius, and verify compatibility with device SFP+ ports and supported link speeds before deployment.
