Direct Attach Copper (DAC) SFP+ cable CBO MCP2102-X005B 10Gbps 24m

The Direct Attach Copper (DAC) SFP+ cable BlueOptics CBO MCP2102-X005B 10Gbps 24m is a passive twinax copper interconnect designed to provide a reliable 10 Gigabit Ethernet link over a 24-metre distance. It connects devices equipped with SFP+ ports such as switches, servers and network interface cards, offering a cost-effective, low-latency alternative to optical transceivers for short-range high-speed networking in data centres and server rooms.

Advantages

This passive SFP+ DAC cable delivers high-bandwidth performance with minimal latency and reduced power consumption compared with active optical solutions. The fixed copper assembly eliminates the need for separate transceivers and fibres, simplifying installation and reducing component count. Its 24 m length provides extended reach within racks or between adjacent racks while maintaining 10 Gbps throughput and consistent signal integrity over twinax cabling.

Suitable for

• Top-of-rack switch to server connections
• Switch-to-switch aggregation within the same room or rack row
• High-performance server uplinks and NIC connections
• Environments where low latency and energy efficiency are required

Key specifications

• Interface type: SFP+ to SFP+
• Data rate: 10 Gbps (full duplex)
• Cable type: Passive twinax copper
• Length: 24 metres
• Typical use: Short-range, rack-to-rack or within-rack connections
• Latency: low, inherent to copper direct attach design
• Power consumption: passive, no external power required for the cable assembly

How to use

Ensure both network devices have compatible SFP+ ports and support passive DAC assemblies. Insert each SFP+ connector into the corresponding port until the latch engages, taking care to align the connector correctly. Verify link status on connected devices and configure network settings as required. For installation, route the cable to avoid sharp bends and mechanical stress; observe recommended bend radius and secure the cable to prevent strain on the connectors.

Recommendations

Use this 24 m SFP+ DAC cable for reliable 10GbE links in data centre aggregation, top-of-rack deployments and server-to-switch uplinks. Avoid exceeding recommended bend radius, keep the cable free from heavy compression, and confirm device compatibility with passive twinax SFP+ interconnects before deployment.
