SFP+ DAC cable CBO MCP2101-X01AB 30m Passive

The SFP+ DAC cable CBO MCP2101-X01AB 30m Passive from BlueOptics is a 30-metre Direct Attach Copper (DAC) twinax cable engineered to provide a fixed, low-latency 10GbE connection between compatible SFP+ ports. As a passive solution, it eliminates the need for separate optical transceivers, offering a compact, plug-and-play link for switches, servers and storage devices in short- to mid-range data center and rack-to-rack environments. The cable is intended for environments where a dependable, cost-effective 10GbE physical link is required and where power consumption from active transceivers should be avoided.

Advantages

The passive twinax design delivers low latency and consistent signal quality while consuming no additional power for signal conversion. With a 30-metre length, the cable extends reach beyond typical short-reach direct attach options while keeping installation simple and minimizing connector layers. Compatibility with standard SFP+ ports simplifies deployment across compatible switches and servers without configuration changes. The fixed-cable form factor reduces component count and potential points of failure compared to solutions that require separate transceivers and fiber patch cords.

Suitable for

• Rack-to-rack 10GbE connections within data centers
• Direct links between switches and aggregation devices
• Server-to-switch or server-to-storage interconnects
• Environments prioritizing low latency and reduced power usage

Key specifications

• Interface type: SFP+ direct attach copper (twinax) cable
• Cable type: Passive twinax copper
• Maximum supported data rate: 10 Gbps per channel (10GbE)
• Length: 30 metres
• Compatibility: Standard SFP+ ports on network switches, servers and storage devices
• Latency: Low fixed-latency physical link typical of passive DAC cables
• Power: Passive operation, no additional power required for transceivers

How to use

Install the cable by inserting each SFP+ connector into the corresponding SFP+ port on the two devices to be connected. Ensure devices are powered and ports are enabled; most operating systems and switches will automatically recognise a passive DAC link and negotiate 10GbE. Route the cable to avoid sharp bends and mechanical strain, and secure it within rack management fixtures if available. When removing the cable, release any retention clips before pulling to avoid damaging the connector or port.

Recommendations

Confirm SFP+ port compatibility with passive DAC cables in device documentation before deployment. Avoid tight bends and maintain the specified bend radius for twinax cables. For installations requiring longer distances or active signal conditioning, consider optical transceivers or active DAC alternatives; for standard short- to mid-reach 10GbE interconnects, this passive 30m twinax cable provides a reliable, low-power link.
