SFP+ DAC cable CBO MCP2103-X002B 30m – direct-attach twinax, 10Gbps

BlueOptics SFP+ DAC cable CBO MCP2103-X002B 30m is a direct-attach twinax copper cable engineered for short-range 10Gbps connections between compatible SFP+ ports. With a 30-meter length and passive twinax design, this cable provides a straightforward physical layer connection for switches, servers and storage systems where cable length is within the supported range. The product targets data center interconnects, rack-to-rack links and other high-speed networking scenarios that demand low latency, predictable performance and energy-efficient cabling.

Advantages

The twinax construction ensures low signal attenuation and stable 10Gbps throughput while avoiding the need for additional transceivers, reducing total hardware cost and power consumption. Passive direct-attach format simplifies installation and minimizes connector count, which can improve signal reliability in short-range links. The 30 m length covers typical intra-rack and adjacent-rack runs in larger data halls, offering a balance between reach and cost-effectiveness for copper cabling solutions.

Suitable for

• 10Gbps links between SFP+ ports on switches and servers
• Rack-to-rack connections within data centers
• Short-range storage area network (SAN) interconnects
• High-density networking deployments where passive DACs reduce power and cost

Key specifications

• Nominal data rate: 10 Gbps
• Cable type: twinax copper direct-attach (DAC)
• Connector type: SFP+ compatible direct-attach ends
• Length: 30 meters
• Typical use: short-range links in data center and rack environments
• Latency: low, suitable for performance-sensitive applications

How to use

Verify that both network devices have SFP+ ports that support passive DAC modules and that firmware or vendor compatibility requirements are met. Route the cable to avoid sharp bends and sources of electromagnetic interference, then insert each SFP+ end fully into the corresponding port until it latches. Ensure both devices negotiate the 10Gbps link and check link/activity indicators on connected equipment. When removing the cable, unlatch from the SFP+ connector carefully to avoid damage to ports or cable ends.

Recommendations

Use this direct-attach twinax cable for short-range, high-throughput connections inside racks or between adjacent racks. Avoid exceeding the specified bend radius and keep the cable run clear of high-power electrical wiring to maintain signal integrity. For runs beyond the recommended distance or when optical isolation is required, consider fiber-based SFP+ transceivers and fiber patching instead.
