Direct Attach Copper (DAC) Cable CBO DAC-SFP-10G-3M-BL 3 m SFP+ 10 Gbit/s

CBO DAC-SFP-10G-3M-BL is a Direct Attach Copper (DAC) cable with SFP+ connectors engineered for short-range 10 Gbit/s links. With a 3 m length, this passive copper assembly connects switches, servers and network interface cards without separate optical transceivers, offering a compact, low-latency physical layer solution suitable for rack and top-of-rack installations in data centers and server rooms.

Advantages

The cable provides a cost-effective and energy-efficient alternative to optical modules for short distances, reducing power consumption and system heat. Direct SFP+ connectors simplify installation and reduce component count. The 10 Gbit/s data rate and copper transmission offer low latency and reliable performance for intra-rack and adjacent-rack connections. Its fixed length and robust connectors support stable mechanical and electrical contact in dense networking environments.

Suitable for

• Short-range 10 Gbit/s connections between switches and servers
• Top-of-rack (ToR) interconnects in data centers
• Direct links between network interface cards (NICs) and switches
• High-density rack deployments where low power and low latency are required

Key specifications

• Connector type: SFP+ to SFP+
• Length: 3 meters
• Maximum data rate: 10 Gbit/s
• Cable type: Direct Attach Copper (DAC), passive
• Typical use range: short-reach, intra-rack or adjacent-rack
• Form factor: flexible copper assembly with integrated connectors

How to use

Insert each SFP+ connector into the corresponding SFP+ port on your network devices until the latch engages. Ensure both ends are fully seated and that connected devices support DAC copper SFP+ modules and the target 10 Gbit/s link speed. Route the cable to avoid sharp bends and excessive tension; maintain the specified bend radius to preserve signal integrity. No additional transceivers or optical cleaning are required for standard passive DAC usage.

Recommendations

Confirm device compatibility with passive SFP+ copper assemblies before deployment. For optimal thermal and electrical performance, use the cable within rack environments and avoid coiling or compressing the cable bundle. If link stability issues occur, verify port settings, cable seating and supported data rates on both endpoints.
