DAC cable CBO SFP-10G-DAC-0.5M 10G direct-attach copper, 0.5 m, SFP+

CBO SFP-10G-DAC-0.5M 10G direct-attach copper, 0.5 m, SFP+ is a short, fixed-length direct-attach copper (DAC) cable with SFP+ connectors designed for reliable 10 Gbps links. It connects SFP+ ports on switches, routers and servers for short-range interconnects, providing a low-latency, energy-efficient alternative to fiber transceivers for top-of-rack and adjacent rack cabling in data centre environments.

Advantages

The DAC cable offers low latency and predictable signal performance over very short distances, reducing the need for separate transceivers and optical fiber patch cords. Its fixed 0.5 m length limits clutter and simplifies cable management in dense rack deployments. With SFP+ interfaces it delivers native 10 Gbps connectivity while consuming less power than equivalent optical setups, making it a cost-effective solution for short-range server and switch links.

Suitable for

• Top-of-rack switch to server connections
• Adjacent rack interconnects in data centres
• Short-distance uplinks between network switches
• High-throughput applications requiring low latency within rack environments

Key specifications

• Connector type: SFP+ to SFP+
• Data rate: 10 Gbps
• Cable type: Direct-attach copper (DAC)
• Length: 0.5 m
• Designed use: Short-range, low-latency interconnects

How to use

Insert each SFP+ connector into the corresponding SFP+ port on your network devices until the retainers click into place. Ensure both devices support direct-attach copper modules and are configured for 10 Gbps operation. After physical installation, verify link status and speed through device management interfaces or LEDs. For safe removal, use the connector latch or pull-tab as provided by the host device to avoid damaging the port.

Recommendations

Use this 0.5 m DAC cable for short, permanent or semi-permanent links where low latency and minimal power consumption are priorities. Avoid tight bends and excessive pulling; maintain recommended bend radius and keep the cable clear of airflow obstructions in the rack. Confirm device compatibility with SFP+ DAC modules and verify firmware or driver requirements before deployment.
