CBO SFP+ Direct Attach Cable EX-SFP-10GE-DAC-50CM 0.5 m Passive, Black

CBO SFP+ Direct Attach Cable EX-SFP-10GE-DAC-50CM is a 0.5 m passive copper twinax cable designed for 10 Gigabit Ethernet interconnects. The cable connects SFP+ ports on switches, servers and network interface cards (NICs) without the need for separate optical transceivers, providing a compact, low-latency option for short-distance links inside racks or between adjacent racks in data center environments.

Advantages

This passive SFP+ DAC offers simplified installation by eliminating transceivers and reducing component count. Its short 0.5 m length minimizes signal loss and latency while maintaining 10 Gbps throughput. The cable’s integrated SFP+ connectors are hot-pluggable and interoperable with standard SFP+ ports, delivering a cost-effective solution for high-density rack connections and short-range network consolidation.

Suitable for

• Rack-to-rack or within-rack 10 Gigabit Ethernet links
• Server to switch or NIC to switch connections
• Data center top-of-rack and adjacent-rack interconnects
• High-density switch stacking and consolidation scenarios

Key specifications

• Form factor: SFP+ direct attach twinax cable
• Length: 0.5 m (50 cm)
• Type: Passive copper (no active electronics)
• Nominal data rate: 10 Gigabit Ethernet (10 Gbps)
• Connector: SFP+ male on both ends, hot-pluggable
• Application: Short-range, within-rack and adjacent-rack links
• Color: Black

How to use

Install the cable by inserting each SFP+ connector into the corresponding SFP+ port on your switch, server or NIC until the latch engages. No additional transceivers or optical modules are required. Ensure ports are powered down or follow hot-plug procedures recommended by your hardware vendor if connecting to active equipment. Verify link status and speed in the device management interface to confirm a 10 Gbps connection.

Recommendations

Use this passive 0.5 m DAC for short, direct connections where fiber transceivers are unnecessary. Avoid routing the cable near sources of mechanical stress or sharp bends; maintain the manufacturer's recommended bend radius. Confirm compatibility with your equipment vendor's supported SFP+ modules list for optimal interoperability.
