SFP+ Direct Attach Cable CBO MCP2104-X01AB-BL 30m Passive

The BlueOptics SFP+ Direct Attach Cable MCP2104-X01AB-BL 30m Passive is a copper twinax assembly designed for short- to mid-range high-speed links between compatible SFP+ ports. This 30-metre passive DAC provides a direct electrical connection for 10Gbps and 25Gbps network interfaces, eliminating the need for separate optical transceivers. It is intended for use in data centers, server rooms and network racks where low latency, predictable performance and cost-efficient cabling are required.

Advantages

The passive direct attach cable offers low latency and low power consumption because no active optics or separate transceivers are required. Its fixed length and integrated connectors reduce component count and simplify installation compared with separate optics and fiber cabling. The cable is plug-and-play with compatible SFP+ ports and provides a stable physical layer connection for high-throughput applications. Its metal and copper construction supports reliable signal integrity across the specified distance.

Suitable for

• 10Gbps and 25Gbps network links between switches and servers
• Top-of-rack and end-of-row connections in data centers
• Interconnects within server racks and between adjacent racks
• Environments requiring low-latency and power-efficient cabling

Key specifications

• Interface type: SFP+ compatible direct attach (twinax copper)
• Transmission modes: supports 10Gbps and 25Gbps line rates
• Length: 30 metres
• Connector: integrated SFP+ form-factor plugs on both ends
• Cable type: passive twinax copper assembly
• Typical use: short- to mid-range rack and data center interconnects

How to use

Ensure both network devices support passive SFP+ direct attach cables and the required line rates before installation. Power down or follow hot-plug guidelines of the equipment as recommended by the device manufacturers. Insert each SFP+ end into the corresponding port until it latches, route the cable to avoid tight bends and secure it within the rack to prevent strain on connectors. After connection, verify link status and negotiated speed via the switch or server management interface.

Recommendations

For reliable operation, avoid exceeding the specified bend radius, keep the cable away from high-temperature sources and EMI-heavy equipment, and confirm compatibility with your switch and server vendors' supported DAC lists when precise vendor interoperability is required.
