Direct Attach Copper (DAC) cable CBO SFP-10G-DAC-0.5M 10G, 0.5 m

CBO SFP-10G-DAC-0.5M is a 0.5 m Direct Attach Copper (DAC) cable designed for 10G network connections between SFP+ ports. It provides a fixed copper link that delivers low latency and consistent performance for short-reach interconnects in racks and network equipment. The cable is intended for direct, plug-and-play use in switches, servers and storage systems where a compact, reliable 10 Gigabit connection is required.

Advantages

The DAC cable offers a compact, low-power alternative to optical modules for short distances, eliminating the need for separate transceivers and fiber patch cords. Its short length and fixed attenuation provide predictable electrical characteristics and minimal latency. The plug-and-play design simplifies installation and reduces points of failure, while the robust connector housings ensure stable mechanical mating in dense rack environments.

Suitable for

• Top-of-rack switch to server 10G connections
• Switch-to-switch short-reach uplinks within the same rack
• Direct connections between storage arrays and hosts
• High-density patching in data center equipment cabinets

Key specifications

• Data rate: 10 Gigabit Ethernet (10G)
• Cable type: Direct Attach Copper (passive DAC)
• Connector type: SFP+ compatible twinax connectors
• Length: 0.5 meters
• Latency: minimal, suitable for short-reach interconnects
• Power consumption: lower than equivalent optical transceiver solutions

How to use

Install the DAC cable by firmly inserting each SFP+ connector into the corresponding SFP+ port on your switches, servers or storage devices until the latch engages. Ensure both ends are fully seated and that connected devices are powered and configured for 10G operation. No additional transceivers or fiber patch cords are required; the connection is typically recognized automatically by network equipment that supports SFP+ copper modules.

Usage recommendations

Use this 0.5 m DAC cable for direct, short-distance links inside racks or between adjacent racks. Avoid tight bends and excessive mechanical stress at the connector junctions. Check device compatibility for SFP+ passive copper modules and verify that the switch or server firmware supports copper DAC detection to ensure proper operation.
