SFP+ Passive DAC Cable CBO MCP2101-X002B 30m — Direct Attach, 10Gbps

The BlueOptics SFP+ Passive DAC Cable CBO MCP2101-X002B 30m is a direct-attach copper solution for 10Gbps links between SFP+ ports. Designed for short-range interconnects in racks and data center environments, this 30-metre passive DAC provides a low-latency, power-efficient connection without the need for separate optical transceivers. The cable supports native SFP+ form-factor connections to switches, servers and storage devices that accept direct-attach cabling.

Advantages

This passive DAC cable delivers consistent 10Gbps bandwidth with minimal latency and reduced power consumption compared with active optics. Its fixed-length, factory-terminated construction simplifies installation and reduces the number of field terminations and spare transceivers required. The 30 m length enables rack-to-rack and short aggregation links while keeping signal integrity over copper for supported equipment. The product is compatible with standard SFP+ cages and provides a cost-effective alternative for short-distance high-speed connections.

Suitable for

• 10Gbps rack-to-rack connections in data centers
• Server-to-switch and switch-to-switch short links
• High-density top-of-rack aggregation where fixed-length copper links are acceptable
• Replacement of short fiber transceiver pairs to reduce cost and power

Key specifications

• Interface: SFP+ direct-attach (fixed copper cable)
• Maximum data rate: 10 Gbps
• Length: 30 metres
• Form factor: SFP+ compatible plugs at both ends
• Latency: passive copper design for low propagation delay
• Power: passive (no additional power required in the cable)
• Environment: intended for short-range, indoor data center use

How to use

Install the DAC by inserting each SFP+ connector into the corresponding SFP+ port on your switch, server or storage device until it latches. Ensure both devices support passive SFP+ direct-attach copper modules and that port configurations (speed and duplex) match on both ends. Route the cable to avoid sharp bends and secure it within the rack to prevent strain on connectors. For best results, power down or gracefully disable ports before insertion or removal where recommended by the equipment vendor.

Recommendations

Verify compatibility with your network equipment vendor and confirm that the devices accept passive DAC modules of the SFP+ form factor. Use the 30 m passive DAC for short-range links inside racks or between adjacent racks; for longer distances or mixed vendor environments consider active optical transceivers or fiber optics. Keep the cable free of kinks, maintain bend radius within vendor guidance, and avoid exposure to moisture or extreme temperatures.
