## Summary description

Passive copper DAC cable CBO SFP28-DAC-0.5M, 0.5 m length, designed for direct connection between SFP28 ports. Provides low-latency, energy-efficient short-range connectivity for switches, routers and network interface cards supporting 25Gbps SFP28 interfaces. Ideal for rack-to-rack or intra-rack links where a fixed, reliable short cable is required.

## Long description

The CBO DAC cable SFP28-DAC-0.5M is a 0.5 m passive copper direct attach cable designed for short-range connections between SFP28 ports. Built for 25Gbps SFP28 interfaces, this cable offers a fixed, low-latency link suitable for high-density network environments such as rack-to-rack or intra-rack connections. As a passive solution, it draws no additional power for signal conditioning and provides a stable physical connection for switches, routers and network interface cards that support SFP28 modules.
Advantages
This passive copper DAC cable delivers low latency and consistent signal integrity over very short distances, while consuming no extra power for active electronics. Its short 0.5 m length minimizes crosstalk and reduces clutter in dense rack environments. The cable is compatible with standard SFP28 ports and provides a cost-effective alternative to active optics for short-reach links, simplifying installation and maintenance.
Suitable for
 Rack-to-rack or intra-rack 25Gbps connections
 Direct links between switches, routers and NICs with SFP28 ports
 High-density server and switch deployments in data centers
 Short-reach interconnects where fixed, reliable cabling is required
Key specifications
 Connector type: SFP28 to SFP28
 Cable type: Passive copper direct attach cable
 Data rate: 25 Gbps per lane (SFP28 standard)
 Length: 0.5 m
 Typical use: Short-reach, direct-attached connections
 Power: Passive — no active signal electronics in the cable
How to use
Ensure both devices have compatible SFP28 ports and are powered off or follow hot-plug guidelines from the equipment vendor. Align and insert each SFP28 connector into the corresponding port until it clicks into place. Verify link status through the network equipment management interface or indicator LEDs. For removal, press the release tab on each connector and pull straight out to avoid bending the cable or connectors.
Usage recommendations
Use the cable for short, fixed links within racks or between adjacent racks. Avoid sharp bends and maintain the manufacturer’s minimum bend radius. Keep the cable away from sources of electromagnetic interference and inspect connectors for dust or debris before insertion to ensure reliable performance.
