Direct Attach DAC Cable CBO CBL-10GSFP-DAC-5M-BL 5 m SFP+ passive copper

BlueOptics CBO CBL-10GSFP-DAC-5M-BL is a 5-meter Direct Attach Copper (DAC) cable with SFP+ connectors, engineered for short-range 10 Gigabit Ethernet links in rack environments. The passive copper assembly eliminates the need for separate optical transceivers, offering a straightforward, low-latency connection between servers, switches and storage devices. Its fixed length and SFP+ form-factor make it suitable for top-of-rack and end-of-row interconnects where cost-efficiency and signal integrity are priorities.

Advantages

The passive SFP+ DAC design delivers reduced power consumption compared to optical solutions by removing active transceiver components. This cable provides low latency and stable signal transmission over a short distance, with a rugged connector interface that supports hot-plug installation. The pre-terminated, factory-tested assembly reduces deployment time and eliminates the need to install and align separate optics and fiber patching.

Suitable for

• 10 Gigabit Ethernet uplinks between switches and aggregation devices
• Server-to-switch connections inside racks
• Storage area network (SAN) short-reach interconnects
• Data center patching and consolidation in 1U/2U rack layouts

Key specifications

• Interface: SFP+ male connectors on both ends
• Cable type: Passive twinax copper assembly
• Length: 5 meters
• Data rate support: 10 Gbps
• Form factor: SFP+ compliant for direct insertion into SFP+ ports
• Use environment: Short-reach, within-rack or adjacent-rack connections

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the network devices until the latch engages. Ensure devices are powered and configured to recognize direct-attach copper modules and that port settings match 10 Gbps operation. No additional transceivers or fiber patch cords are required. For hot-plug procedures, follow the equipment vendor’s guidance to avoid link flapping during equipment changes.

Usage recommendations

For reliable operation, route the cable to avoid sharp bends and mechanical stress; maintain the minimum bend radius specified by the manufacturer. Use this passive DAC for short distances inside racks or adjacent racks; for longer runs or when electrical isolation is required, consider active DACs or optical transceivers with fiber cabling. Verify compatibility with switch and server vendors if vendor-specific link negotiation or port validation is enforced.
