CBO DAC SFP+ Cable Mellanox MCP2104-X002B 30 m Passive

CBO DAC SFP+ Cable Mellanox MCP2104-X002B 30 m Passive is a 30-meter passive Direct Attach Copper (DAC) SFP+ cable designed for short-reach, high-speed interconnects. The cable supports 10GbE-class links between compatible SFP+ ports on switches, servers and storage devices, providing a cost-effective, low-latency physical connection for rack-to-rack and short campus links. It is built for environments where electrical twinax connectivity is preferred over optical transceivers for simplicity and lower total cost of ownership.

Advantages

The passive DAC design delivers low latency and predictable signal quality without the need for separate transceivers or power-hungry active components. A 30 m length extends the useful reach beyond typical short DACs, enabling flexible placement of racks and equipment within data halls. Compatibility with Mellanox SFP+ ports ensures straightforward plug-and-play installation in supported infrastructure, and the copper construction simplifies handling and grounding compared with fiber optic assemblies.

Suitable for

• 10 Gigabit Ethernet links between switches, servers and storage in data centers
• Rack-to-rack and within-room connections in server rooms and network closets
• Short campus backhaul where optical transceivers are not required

Key specifications

• Connector type: SFP+ to SFP+
• Cable type: Direct Attach Copper (passive twinax)
• Supported data rate: up to 10 Gbps per link
• Length: 30 meters
• Typical use: short-reach electrical interconnects for 10GbE-class networks
• Construction: copper twinax with molded connectors

How to use

Install the cable by inserting each SFP+ connector into the corresponding SFP+ port on the devices to be linked. Ensure ports are powered down or follow hot-plugging guidelines from your hardware vendor if connecting to live equipment. Verify link status and speed in the host network interfaces or switch management interface. For best results, route the cable to avoid tight bends and mechanical strain on the connectors and secure excess length to prevent movement or interference.

Recommendations

Use this passive DAC cable for intra-rack and adjacent-rack connections where distances are within 30 m and where a direct copper link simplifies deployment. Confirm port compatibility with Mellanox SFP+ modules and follow standard ESD precautions during installation. Avoid exposure to temperatures and environments outside the equipment manufacturers' specifications to maintain signal integrity and cable longevity.
