## Summary description

Passive SFP28 direct attach copper (DAC) cable by CBO, model SFP28-DAC-0.5M, 0.5 meter length. Designed for short-reach 25Gbps connections between compatible SFP28 ports in switches, NICs and servers. Offers low-latency, cost-effective cabling for rack-to-rack or intra-rack links where passive copper is suitable and power budget is adequate.

## Long description

Passive SFP28 Direct Attach Copper Cable CBO SFP28-DAC-0.5M is a 0.5 metre twinax copper interconnect designed for short-reach 25Gbps links between compatible SFP28 ports in switches, network interface cards and servers. The cable provides a low-latency, cost-efficient physical layer connection for rack-to-rack or intra-rack applications where passive copper meets the power and reach requirements. The product is intended for environments that require straightforward, high-speed electrical links without the need for active transceivers.
Advantages
This passive SFP28 DAC delivers a compact, plug-and-play solution with minimal insertion loss and predictable electrical performance at 25Gbps. It reduces component count and power consumption compared with active optics for short distances and simplifies installation by using the standard SFP28 form factor. The cable's short length minimizes signal attenuation and crosstalk, supporting reliable interconnects in dense rack deployments.
Suitable for
 Short-reach 25Gbps connections between SFP28 ports
 Rack-to-rack or intra-rack links in data centres
 Connections between switches, NICs and servers
 Environments where passive copper meets power and distance requirements
Key specifications
 Data rate: 25 Gbps per lane (SFP28 standard)
 Length: 0.5 metre
 Connector type: SFP28 twinax copper plugs (fixed cable)
 Cable type: Passive twinax copper
 Typical applications: short-reach electrical interconnects in racks
How to use
Insert each SFP28 connector into the corresponding SFP28 port on the networking devices until the latch clicks. Ensure both ends are fully seated and that connected devices support passive DACs at 25Gbps. Verify link status through device LEDs or management interfaces and perform standard network testing to confirm throughput and error rates. Avoid sharp bends and excessive mechanical stress on the cable to maintain signal integrity.
Usage recommendations
Use this passive SFP28 DAC for short, high-speed connections where power savings and low latency are priorities. Confirm device compatibility with passive copper cables and ensure the cable length and thermal conditions are appropriate for reliable operation.
