## Summary description

Passive copper Direct Attach Cable (DAC) CBO SFP28-DAC-0.5M is a 0.5 m SFP28-to-SFP28 interconnect designed for short-reach 25GbE or compatible SFP28 ports. The fixed short-length cable provides low-latency, energy-efficient connectivity between switches, NICs and storage devices in rack environments. Ideal for data centre and server top-of-rack connections where a compact, reliable link is required.

## Long description

Passive copper Direct Attach Cable (DAC) CBO SFP28-DAC-0.5M is a 0.5 m SFP28-to-SFP28 interconnect designed for short-reach 25GbE or compatible SFP28 ports. The compact, fixed-length cable provides a direct electrical link between network devices in rack environments, offering low latency and reduced power consumption compared with active optical alternatives. The cable is intended for connecting switches, network interface cards and storage devices where a reliable short cable is needed.
Advantages
The passive copper design delivers low latency and energy-efficient operation without requiring separate transceivers or external power. Its short 0.5 m length reduces cable clutter and simplifies rack wiring while maintaining signal integrity for 25GbE connections. The SFP28 form-factor ensures broad compatibility with SFP28 ports on switches and NICs, and the fixed-assembly construction minimizes points of failure for stable, maintenance-friendly operation.
Suitable for
Top-of-rack switch-to-switch connections in data centres
Direct links between server NICs and storage controllers
Short-reach interconnects in blade servers and dense rack deployments
Patch connections inside equipment racks where 0.5 m length is sufficient
Key specifications
Interface: SFP28 on both ends
Data rate: up to 25 Gigabit Ethernet
Cable type: passive copper direct attach
Length: 0.5 metres
Form factor: fixed double-ended assembly for short-reach connections
Typical use environment: rack-mounted network equipment and servers
How to use
Connect one SFP28 end to the SFP28 port of the first device and the other end to the second device while both devices are powered according to their respective procedures. Ensure ports are configured for 25GbE or an auto-negotiated compatible speed and verify link status through the device management interface. Use the cable for direct, short-distance links inside racks; avoid bending the cable beyond manufacturer-recommended bend radius and avoid routing near high-power electrical sources to maintain signal quality.
Usage recommendations
For reliable operation, use the cable in short-reach scenarios up to 0.5 m within racks and enclosures. Confirm compatibility with the device vendor’s SFP28 port support and firmware recommendations, and inspect connectors for debris before insertion. Store the cable coiled without sharp kinks and avoid stretching or pulling on the cable to prolong service life.
