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

The CBO DAC SFP+ SFP-10G-DAC-0.5M is a 10Gbps direct-attach copper (DAC) cable with a fixed 0.5 m length designed for short-reach interconnects. It connects devices with SFP+ ports — such as switches, servers and network interface cards — to provide a stable, low-latency, low-power 10 Gigabit link. The cable is intended for within-rack or rack-to-rack connections in data centers, server rooms and network closets where a compact, cost-effective copper solution is preferred over optical transceivers.

Advantages

This SFP+ DAC cable delivers a high-bandwidth 10Gbps channel with minimal latency and reduced power consumption compared with active optical modules. Its fixed 0.5 m length reduces clutter and simplifies cable management in dense rack environments. The passive copper design eliminates the need for separate transceivers, lowering total hardware cost and easing deployment. Compatibility with standard SFP+ ports ensures plug-and-play connectivity for common networking equipment.

Suitable for

• Short-reach connections between switches and servers in the same rack
• Rack-to-rack links in adjacent cabinets
• Direct links from servers to NICs or storage controllers
• High-density top-of-rack and network closet installations

Key specifications

• Interface: SFP+ to SFP+
• Data rate: 10 Gbps
• Cable type: Direct-attach copper (DAC), passive
• Length: 0.5 metre
• Typical use: Short-reach intra-rack and inter-rack connections
• Latency: low, suited for latency-sensitive traffic
• Power consumption: lower than equivalent optical transceiver solutions

How to use

Insert each SFP+ connector into the corresponding SFP+ port on your network devices until the latch engages. Ensure devices are powered down or that hot-plugging is supported by the hardware before insertion or removal. After connection, verify link status and speed on both endpoints and configure interface settings on your switches or servers as required. Use the 0.5 m length to maintain tidy cable routing within racks or between adjacent racks.

Recommendations

Use this 0.5 m DAC cable for short fixed-distance links where a cost-efficient, low-latency 10Gbps connection is needed. Avoid using this passive copper cable for longer distances or in environments requiring optical isolation. Verify SFP+ port compatibility and firmware support on your networking equipment prior to deployment.
