## Summary description

Passive DAC cable CBO SFP28-DAC-0.5M (0.5 m) provides a short-distance direct-attach copper connection for SFP28 ports. Designed for 25GbE and compatible SFP28 interfaces, it offers low latency and reduced power compared with optical transceivers for rack-to-rack or within-rack links. Ideal for switches, servers and storage where cost-effective, reliable short-reach connectivity is required.

## Long description

Passive DAC cable CBO SFP28-DAC-0.5M is a 0.5 m direct-attach copper connection designed for SFP28 ports and 25GbE links. The cable provides a short-range physical link suitable for within-rack and rack-to-rack interconnects between switches, servers and storage devices. As a copper direct-attach solution, it delivers low latency and lower power consumption compared with active copper modules or optical transceivers, while keeping cost and complexity to a minimum.
Advantages
This passive SFP28 direct-attach cable offers reliable electrical connectivity optimized for 25 Gigabit Ethernet environments. Its short fixed length reduces signal degradation and simplifies cable management in dense rack deployments. The passive design eliminates the need for separate transceivers and reduces overall power draw. The cable is compatible with standard SFP28 ports and is intended to provide consistent throughput and low latency for short-reach applications.
Suitable for
 Short-reach connections between switches within the same rack
 Rack-to-rack links in data center topologies
 Direct server-to-switch or server-to-storage connections
 Environments requiring low-latency 25GbE links
Key specifications
 Cable type: Passive direct-attach copper (DAC)
 Connector type: SFP28 on both ends
 Supported data rate: 25 Gigabit Ethernet
 Length: 0.5 m
 Use case: Short-reach, within-rack and rack-to-rack interconnects
 Performance characteristics: Low latency, reduced power consumption compared with optical transceivers
How to use
Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on your network devices until the latch engages. Ensure both ends are fully seated and that connected devices are powered and configured for 25GbE operation. For hot-pluggable ports, connect or disconnect the cable following your equipment vendor’s procedures to avoid port damage. Verify link status through device management interfaces and test throughput after installation.
Usage recommendations
Use this 0.5 m passive DAC for short, point-to-point links where distance does not exceed the cable length and where low latency and low power are priorities. Avoid routing the cable near strong electromagnetic interference sources and prevent tight bends; maintain minimum bend radius recommended by the equipment manufacturer. For longer distances or environments requiring isolation and optical reach, consider active copper or optical transceiver solutions.
