Cable DAC CBO DAC-SFP-25G-1M-BL — 1 m SFP28 Direct Attach 25 Gbit/s

CBO DAC-SFP-25G-1M-BL is a 1 m SFP28 direct attach copper (DAC) cable that supports 25 Gbit/s data rates for short-range, high-speed connections. It is designed for use between compatible SFP28 ports in switches, servers and other network appliances to provide a low-latency, energy-efficient link for data center and rack-to-rack interconnects. The cable integrates SFP28 connectors on both ends and is intended for fixed, short-distance wiring where optical transceivers are not required.

Advantages

The DAC cable delivers high throughput at 25 Gbit/s while maintaining low latency and low power consumption compared with active optical solutions. Its one-meter length reduces excess slack in dense rack environments and simplifies cable management. The integrated SFP28 connectors eliminate the need for separate transceivers and provide a cost-effective option for short-range links. The copper construction offers reliable signal integrity for typical intra-rack and short inter-rack distances.

Suitable for

• Short-range interconnects between switches and top-of-rack devices
• Direct connections from servers to network interface ports supporting SFP28
• Data center rack-to-rack links where 25 Gbit/s throughput is required
• Environments prioritizing low latency and reduced power usage

Key specifications

• Connector type: SFP28 on both ends
• Length: 1 meter
• Supported data rate: 25 Gbit/s
• Cable type: Direct attach copper (DAC)
• Use case: Short-range, fixed copper interconnect

How to use

Insert each SFP28 connector into the corresponding SFP28 port on the networking devices until the module latches. Verify link status on both devices and ensure the ports are configured for 25 Gbit/s operation if required by the equipment. Route the cable to avoid sharp bends and mechanical stress; the short one-meter length is suitable for tidy intra-rack routing. If the link does not establish, confirm port compatibility and check device firmware or interface settings.

Recommendations

Use the DAC cable for short, permanent links inside racks or between adjacent racks. Avoid using the cable for distances beyond its rated short-range performance and keep it clear of heat sources and heavy cable bundles to maintain signal integrity and easy serviceability.
