Direct Attach Copper (DAC) cable CBO SFP-10G-DAC-0.5M 10Gbps 0.5 m SFP+ to SFP+

CBO SFP-10G-DAC-0.5M is a 0.5 metre direct attach copper (DAC) cable designed for 10Gbps SFP+ ports. The cable connects compatible network equipment such as switches, servers and network interface cards with a low-latency, energy-efficient copper link suited to short-reach interconnects in racks and data centre topologies. The fixed-length, twin-axial copper construction delivers a straightforward plug-and-play connection for applications that require reliable 10 Gigabit Ethernet links without the need for optical transceivers.

Advantages

The DAC cable offers a compact, pre-terminated solution that reduces latency and power consumption compared with optical modules and separate SFP+ transceivers. Its short 0.5 m length minimises signal degradation and is ideal for direct device-to-device connections within the same rack or adjacent racks. The SFP+ to SFP+ form factor ensures compatibility with equipment that supports standard SFP+ ports and provides a predictable electrical interface for 10Gbps traffic.

Suitable for

• High-density rack connections between switches and servers
• Top-of-rack and end-of-row short-reach links in data centres
• Direct connections between network interface cards and switches
• Test and lab environments requiring stable 10GbE links

Key specifications

• Data rate: 10 Gbps
• Length: 0.5 metre
• Connector type: SFP+ to SFP+
• Cable type: Passive direct attach copper (DAC), twin-axial
• Latency: low, suitable for short-reach applications
• Typical use environment: rack-mounted equipment and data centre interconnects

How to use

Insert each SFP+ connector into the SFP+ port of the devices to be linked, ensuring that the connector latch engages. No additional configuration or external power is required for passive DAC operation; once seated correctly the devices should detect the 10Gbps link automatically. For best results verify that connected devices support passive SFP+ direct attach cables and check port settings in the network equipment management interface if the link does not come up immediately.

Recommendations

Use the cable for short-distance links within the same rack or adjacent racks to maintain signal integrity; avoid tight bends at the connector boot and keep the cable clear of sources of electromagnetic interference. Confirm SFP+ compatibility with your network equipment vendor documentation before deployment.
