DAC cable CBO CBL-10GSFP-DAC-5 5m SFP+ direct-attach copper cable

The BlueOptics DAC cable CBO CBL-10GSFP-DAC-5 5m SFP+ direct-attach copper cable is a pre-terminated SFP+ twinax assembly for short-range 10 Gbps connections. It uses SFP+ connectors on both ends and a fixed 5 m copper twinax conductor to deliver low-latency, energy-efficient links between compatible switches, servers and network interface cards. The cable is intended for rack-to-rack and top-of-rack placements in data centers and enterprise network environments where SFP+ ports are available and a straightforward, plug-and-play connection is required.

Advantages

This direct-attach copper cable offers a cost-effective alternative to optical modules and fibre for short distances, with lower power consumption and negligible configuration needs. Its fixed-length, factory-terminated SFP+ connectors simplify installation and reduce points of failure compared to field-terminated assemblies. The cable supports full 10 Gbps throughput with minimal latency and is suitable for dense rack environments where predictable electrical performance and compatibility with standard SFP+ ports are required.

Suitable for

• Rack-to-rack connections in data centers
• Top-of-rack to server links
• Switch-to-switch or switch-to-server short-distance links
• Environments where low power and low latency are priorities

Key specifications

• Connector type: SFP+ on both ends
• Cable type: Direct-attach copper (twinax)
• Nominal data rate: 10 Gbps
• Length: 5 meters
• Latency: low, suitable for time-sensitive traffic
• Installation: plug-and-play, no transceivers required
• Typical use: short-range interconnects within racks or between adjacent racks

How to use

Ensure both network devices have compatible SFP+ ports and support direct-attach copper assemblies. Power down devices if recommended by the equipment manufacturer, align the SFP+ connectors with the ports and insert the cable until the retention latch engages. After connection, verify link status through device LEDs or management interfaces and confirm 10 Gbps operation in the network management system. For removal, disengage the retention latch and pull straight out to avoid damaging the connector or port.

Usage recommendations

Use the cable for runs within the validated 5 m distance and avoid tight bends or kinks; maintain the manufacturer’s minimum bend radius. Prefer direct rack-to-rack or top-of-rack deployments for predictable performance. If longer runs or optical isolation are required, choose fibre-optic transceivers and cabling instead.
