Suitable for switches, NICs and storage systems supporting SFP28. Benefits include compact cabling, reduced power and lower cost for short-distance links.

## Long description

Passive copper DAC cable CBO SFP28-DAC-0.5M is a 0.5 metre direct-attach cable designed for SFP28 ports. It provides a short, low-latency physical connection between compatible network devices without the need for separate optical transceivers. The cable is intended for high-speed links where short reach, low power consumption and compact cabling are priorities, and is suitable for use between switches, network interface cards and storage systems that support SFP28.
Advantages
This passive SFP28 direct-attach cable offers a simplified physical layer connection that reduces component count and energy consumption compared with optical transceivers. Its short 0.5 m length minimises cable clutter in dense rack environments, and the copper construction delivers low latency and stable electrical performance for short-distance high-speed links. The cable is plug-and-play with SFP28-compatible ports and typically requires no additional configuration or power.
Suitable for
 Point-to-point connections between switches in the same rack or adjacent racks
 Direct links from servers or NICs to top-of-rack switches
 Interconnects for storage arrays and SAN equipment with SFP28 ports
 Short-reach data centre links where low latency and reduced power are required
Key specifications
 Connector type: SFP28 direct-attach (copper)
 Length: 0.5 metre
 Cable type: Passive twinax copper DAC
 Supported interface: SFP28 (25 Gbps per lane)
 Suitable reach: short-distance / in-rack or adjacent-rack connections
 Latency: low electrical latency suitable for high-performance links

How to use
Insert the SFP28 connectors into the SFP28 ports of the two devices to be connected, ensuring each connector latches securely. No additional transceivers, optical modules or external power are required. After physical installation, verify link status on the connected devices and check port configuration and speed settings if necessary. Use firmware or driver updates recommended by device manufacturers to ensure compatibility with passive SFP28 DACs.
Usage recommendations
Use this 0.5 m passive copper DAC for in-rack or adjacent-rack high-speed connections where optical modules are unnecessary. Avoid using the cable for longer runs beyond the recommended short-reach range. Handle connectors by the housing, avoid sharp bends in the cable, and keep contact dust-free when inserting or removing the cable to maintain reliable electrical performance.
