SFP+ Passive DAC Cable CBO MCP2104-X003B 30m for 10Gbps Direct Attach

CBO MCP2104-X003B is a 30-meter passive SFP+ Direct Attach Copper (DAC) cable engineered for 10Gbps links between SFP+ ports. It delivers a fixed, low-latency electrical connection intended for short- to medium-range interconnects in racks and data centres, providing a straightforward option for connecting switches, servers and storage devices without active transceivers. The cable is designed to reduce power consumption and simplify cabling at the rack level while supporting standard 10 Gigabit Ethernet signalling over a copper assembly.

Advantages

The passive SFP+ DAC design offers lower power draw compared with active optical transceivers and fewer points of failure due to its integrated copper construction. With a 30 m length, this cable supports flexible rack layouts and equipment placement within small- to medium-sized data halls. The fixed electrical interface ensures minimal latency and predictable signal behaviour for 10Gbps links, while the construction and connector compatibility provide reliable mating with SFP+ ports that accept passive copper assemblies.

Suitable for

• Short- to medium-range connections between network switches
• Direct links between servers and storage enclosures
• Top-of-rack and middle-of-row cabling in data centres
• Environments requiring cost- and power-efficient 10GbE interconnects

Key specifications

• Interface: SFP+ electrical direct attach copper
• Data rate: 10 Gbps
• Length: 30 metres
• Cable type: Passive copper assembly
• Latency: Low, fixed electrical link

How to use

Install the DAC cable by inserting each SFP+ connector into the corresponding SFP+ port on the devices to be connected. Ensure ports are powered down or follow hot-plug instructions from the equipment vendor if applicable. Verify link status and speed on both endpoints after insertion and confirm that device firmware or drivers support passive SFP+ copper modules. Route the cable to avoid sharp bends and mechanical strain and secure it within the rack to maintain proper airflow and accessibility.

Recommendations

Use this passive SFP+ DAC cable where short- to medium-distance 10GbE links are needed and where reduced power consumption and predictable latency are priorities. Verify compatibility with your equipment vendor’s SFP+ port policy and avoid exposure to excessive mechanical stress or temperatures outside the vendor-specified operating range.
