Cable DAC SFP+ CBO SFP-10G-DAC-0.5M 10Gbps Direct Attach Copper, 0,5 m

The CBO DAC SFP+ cable SFP-10G-DAC-0.5M 10Gbps direct attach copper, 0.5 m is a passive, short-reach interconnect designed for 10 Gigabit Ethernet links between SFP+ ports. With a fixed length of 0.5 m, this direct attach copper (DAC) cable provides a low-latency, power-efficient physical connection suitable for in-rack and adjacent-rack server, switch and storage equipment. The cable integrates SFP+ compliant connectors on both ends, eliminating the need for separate optical transceivers while maintaining the 10Gbps data rate required for high-throughput environments.

Advantages

This passive DAC cable delivers predictable electrical performance for short-distance 10Gbps links, with reduced latency compared to optical alternatives and lower power consumption due to the absence of active transceivers. Its compact, fixed-length form factor simplifies cable management in dense rack installations and helps maintain signal integrity for short, high-speed interconnects. Compatibility with standard SFP+ ports enables straightforward installation and interoperability across devices that support direct attach copper connections.

Suitable for

• Short-range server-to-switch or switch-to-switch connections within a rack
• Rack-to-rack links in adjacent cabinets where 0.5 m is sufficient
• Direct connections between servers and storage arrays with SFP+ ports
• High-throughput, low-latency environments such as virtualized hosts and database clusters

Key specifications

• Interface: SFP+ connectors on both ends
• Data rate: 10 Gbps
• Cable type: Passive direct attach copper (DAC)
• Length: 0.5 meters
• Typical use case: Short-range in-rack or adjacent-rack interconnects
• Latency: Low, inherent to copper direct attach links
• Power: No active transceiver power consumption

How to use

Verify that both devices have SFP+ ports that support passive direct attach copper connections. With both systems powered on or according to your maintenance procedures, align the SFP+ connector latches and insert each end into the corresponding SFP+ port until it clicks into place. Confirm link status in the device management interface or indicator LEDs. For removal, release the connector latch and gently pull the module straight out to avoid damaging the port.

Recommendations

Use this 0.5 m DAC cable for short, fixed connections where a low-latency, energy-efficient 10Gbps link is needed. Avoid running the cable tightly bent or under strain; maintain the manufacturer’s minimum bend radius and avoid exposure to sources of electromagnetic interference. For longer distances or environments requiring optical isolation, choose an appropriate fiber optic solution instead.
