DAC cable CBO SFP-10G-DAC-0.5M 0.5 m SFP+ direct-attach copper for 10Gbps links

CBO DAC cable SFP-10G-DAC-0.5M is a 0.5 m direct-attach copper (DAC) cable with SFP+ connectors, engineered for 10 Gigabit Ethernet short-reach interconnects. The cable connects SFP+ ports on switches, servers and network interface cards without requiring separate optical transceivers. Its compact length and direct-attach design make it suitable for within-rack and adjacent-rack connections where low latency, predictable performance and reduced power consumption are priorities.

Advantages

The DAC cable provides a low-latency, low-power alternative to fiber optics and active transceiver pairs, offering cost-effective 10Gbps links for short distances. Its fixed cable assembly eliminates the need to purchase and manage separate transceiver modules, simplifying inventory and reducing total cost of ownership. The direct-attach copper design supports stable electrical transmission with minimal configuration and plug-and-play compatibility with SFP+ ports that accept DAC assemblies.

Suitable for

• Within-rack server-to-switch connections
• Rack-to-adjacent-rack interconnects in data centers
• High-performance NIC to switch links where 10Gbps is required
• Environments seeking lower power and cost compared with optical modules

Key specifications

• Connector type: SFP+ direct-attach copper (fixed assembly)
• Cable length: 0.5 m
• Data rate: up to 10 Gbps
• Latency: low, suitable for short-reach applications
• Typical use: short-distance electrical connections between SFP+ ports

How to use

Install the DAC cable by inserting each SFP+ connector into the corresponding SFP+ port on the network devices until the latch clicks. Ensure both devices are powered and configured for 10Gbps operation; most switches and NICs detect the connection automatically and negotiate link parameters. Avoid excessive bending near the connector ends and secure any cable routing to prevent mechanical strain. For troubleshooting, verify link LEDs on both devices and check port settings in device management interfaces.

Recommendations

Use this 0.5 m DAC cable for short, direct connections inside racks or between adjacent racks where optical transceivers are unnecessary. Verify compatibility lists provided by your switch or server vendor for SFP+ DAC support and ensure proper handling to maintain connector integrity.
