SFP+ Direct Attach Cable CBO MCP2103-X02AB 30m Passive

The SFP+ Direct Attach Cable CBO MCP2103-X02AB 30m Passive is a fixed copper interconnect designed for 10GbE links between compatible SFP+ ports. This 30 metre passive DAC provides a direct, low-latency physical connection for short- to medium-reach applications in racks and data centres. It is intended for use where a simple, cost-effective 10Gbps link is needed between servers, switches or storage devices that accept SFP+ direct attach modules.

Advantages

This passive SFP+ direct attach cable minimises latency and power consumption because it contains no active electronics. The 30 m length supports flexible rack-to-rack and row-to-row placements without additional transceivers or optical modules. Compatibility with standard SFP+ ports simplifies installation and reduces the need for fibre patching, while the fixed copper construction offers predictable signal characteristics and lower total cost of ownership compared with optical alternatives for similar short- to medium-range links.

Suitable for

• Server-to-switch 10GbE connections in data centres
• Switch-to-switch interconnects within the same room or adjacent racks
• Storage networking requiring low-latency 10Gbps links
• Top-of-rack and end-of-row cabling within enterprise and campus networks

Key specifications

• Interface: SFP+ direct attach copper cable for SFP+ ports
• Nominal data rate: 10 Gigabit Ethernet (10GbE)
• Cable type: Passive twinax copper assembly
• Length: 30 metres
• Latency: Low, passive copper link with minimal added delay
• Power: Passive design, no external power required
• Typical applications: Short- to medium-reach rack and row interconnects

How to use

Install the cable by inserting each SFP+ connector into the corresponding SFP+ port on the devices to be linked, ensuring the latch mechanism engages. Verify link status through the connected devices' network interface indicators or management console. No firmware or driver installation is required for the cable itself; configuration is handled by the host devices. When removing the cable, release the latches before pulling to avoid damage to ports or connectors.

Recommendations

To maintain optimum performance, route the cable to avoid sharp bends and mechanical strain; observe the manufacturer’s minimum bend radius. Use the 30 m passive DAC for links within the same data centre room or between adjacent racks. For longer distances or environments requiring electrical isolation, consider fibre optic solutions instead.
