Cabo DAC CBO CPAC-DAC-10G-3M — 10 Gbit/s, 3 m, cobre de ligação direta

CBO CPAC-DAC-10G-3M is a direct-attach copper (DAC) cable engineered for short-range 10 Gbps links. At 3 metres length, this cable connects switches, routers and network interface cards without separate optical transceivers, offering a compact solution for rack-to-rack or within-rack high-speed interconnects in data centres and server rooms. The passive copper design reduces latency and maintains signal integrity for reliable performance on short distances.

Advantages

The cable supports 10 Gbps throughput while eliminating the need for additional SFP+ transceivers, which simplifies installation and lowers component count. Its direct-attach form factor provides stable low-latency links and predictable electrical characteristics suited to short interconnect runs. The fixed 3 m length is convenient for common rack layouts and helps to avoid excess cabling. The robust connectors and shielding ensure consistent signal quality in dense networking environments.

Suitable for

• Rack-to-rack connections in data centres
• Within-rack interconnects between switches and servers
• Short links between routers and network interface cards (NICs)
• High-density network switch deployments

Key specifications

• Data rate: 10 Gbps
• Length: 3 metres
• Cable type: Direct-attach copper (DAC), passive
• Connector type: SFP+ compatible direct-attach connectors
• Use case: Short-range, within-rack and rack-to-rack interconnects
• Typical latency: low, suitable for high-performance networking

How to use

Insert each end of the DAC cable into the SFP+ ports of the devices to be connected, ensuring the connectors are aligned and fully seated. No separate transceivers or fibre patching is required; the cable functions as an integrated copper link. Verify link status on connected equipment and check interface settings such as speed and duplex if necessary. Handle the cable carefully to avoid sharp bends and maintain recommended bend radius for copper DAC assemblies.

Recommendations

Use this 3 m DAC cable for short, high-bandwidth connections within racks or between adjacent racks. Avoid using passive DACs for runs longer than their rated distance and keep the cable away from sources of strong electromagnetic interference for best signal integrity.
