Direct Attach Copper (DAC) Cable CBO DAC-SFP-10G-2M-BL 2 m SFP+ 10 Gbit/s

BlueOptics Direct Attach Copper (DAC) Cable CBO DAC-SFP-10G-2M-BL is a 2 meter SFP+ passive copper cable engineered for short-range, high-speed connections. Supporting 10 Gbit/s data rates with SFP+ form-factor connectors, this DAC cable provides a low-latency, energy-efficient link for interconnecting switches, servers and storage within racks or between adjacent racks. The cable offers plug-and-play operation with hot-pluggable SFP+ ends and is suitable for environments where cost-effective, reliable 10 Gigabit links are required over short distances.

Advantages

This Direct Attach Copper cable delivers 10 Gbit/s throughput with minimal signal latency and reduced power consumption compared to optical transceivers. Its passive SFP+ connectors allow immediate recognition by compatible SFP+ ports without additional transceivers, simplifying installation and reducing component count in the network. The fixed 2 m length is optimized for rack-to-rack and switch-to-server runs, ensuring predictable performance and a neat cable layout in dense data centre setups.

Suitable for

• Short-range 10 Gbit/s interconnects between switches and servers
• Rack-to-rack connections in data centres and server rooms
• High-density switch stacks and Top-of-Rack (ToR) deployments
• Direct server-to-storage links within the same rack

Key specifications

• Connector type: SFP+ on both ends
• Data rate: 10 Gbit/s
• Cable length: 2 m
• Cable type: Twinaxial direct attach copper (passive)
• Latency: low, suitable for time-sensitive applications
• Power: passive design with reduced power compared to optics

How to use

Install the cable by inserting each SFP+ connector into the SFP+ port of the devices to be linked; ensure connectors are fully seated and retention latches engage. No additional transceivers or configuration are required for standard SFP+ ports. Verify link status on both devices and check network diagnostics to confirm 10 Gbit/s operation. For safe operation, power down devices if recommended by the equipment manufacturer before connecting or disconnecting the cable in live environments.

Recommendations

Use this 2 m DAC cable for intra-rack or adjacent-rack connections where short, high-bandwidth links are needed. Avoid bending the cable sharply or routing it near sources of strong electromagnetic interference. Confirm SFP+ port compatibility with your network equipment and follow vendor guidance for hot-plug procedures to maintain reliable operation.
