SFP+ DAC cable CBO MCP2101-X001B 30 m Passive for 10GbE interconnects

The BlueOptics SFP+ DAC cable CBO MCP2101-X001B is a passive 30 m direct attach copper (DAC) designed for 10GbE interconnects between switches, servers and storage. This 30-meter fixed copper link provides 10 Gigabit Ethernet connectivity without optical transceivers, offering a low-latency, energy-efficient solution for short-to-medium distance rack-to-rack and within-rack connections. The cable is intended for environments where a reliable, high-bandwidth physical connection is required and optical conversion is not necessary.

Advantages

The passive design eliminates the need for separate optical modules, reducing component count and simplifying deployment. The copper construction delivers consistently low latency and stable throughput for 10GbE links, while consuming less power compared with active or optical solutions. At 30 meters, this DAC cable covers typical data centre and equipment-room distances where cost-effective, high-speed interconnects are preferred. Compatibility with standard SFP+ ports ensures straightforward integration into existing network hardware that supports passive SFP+ DACs.

Suitable for

• Rack-to-rack 10 Gigabit Ethernet connections in data centres
• Within-rack interconnects between switches, servers and storage arrays
• Short-to-medium distance uplinks and aggregation links
• Environments prioritising low-latency, energy-efficient cabling

Key specifications

• Cable type: Passive SFP+ Direct Attach Copper (DAC)
• Data rate: 10 Gigabit Ethernet (10GbE)
• Length: 30 metres
• Connector: SFP+ compatible plug-terminated ends
• Latency: low, fixed copper link characteristics
• Power: passive, no additional power required for the cable itself
• Typical use range: short-to-medium data centre distances (within-rack and rack-to-rack)

How to use

Install the DAC cable by inserting each SFP+ connector into the corresponding SFP+ port on the network devices until the latch engages. Ensure both ends are seated firmly and that connected equipment supports passive SFP+ DAC cables. Route the cable within rack management channels or cable trays to avoid sharp bends and excessive strain; observe the manufacturer's minimum bend radius for copper cables. Verify link status and configuration on the devices after physical installation and perform any required interface configuration for 10GbE operation.

Recommendations

For reliable performance, use the cable in data centre and equipment-room environments within the specified 30 m distance. Maintain proper airflow and avoid routing near sources of intense electromagnetic interference. Confirm device compatibility with passive SFP+ copper DACs in the switch or server documentation prior to deployment, and label both ends to simplify future maintenance and troubleshooting.
