## Summary description

Passive DAC cable CBO SFP28-DAC-0.5M is a 0.5 meter SFP28 direct attach copper cable for short-reach 25GbE connections. Designed for direct server-to-switch or switch-to-switch links supporting SFP28 ports, it provides low-latency, low-power connectivity without transceivers. Ideal for data center top-of-rack, server racks and high-density networking where short, reliable 25GbE links are required.

## Long description

Passive DAC cable CBO SFP28-DAC-0.5M is a 0.5 meter direct attach copper cable engineered for short-reach 25GbE connections. The cable integrates two SFP28 connectors on a fixed copper assembly to enable direct server-to-switch or switch-to-switch links without separate transceivers. Its compact length and passive design reduce power consumption and latency compared with active modules, making it suitable for high-density network environments such as top-of-rack and server-rack interconnects.
Advantages
The SFP28 passive DAC provides a straightforward, low-latency 25GbE connection with minimal power draw and simplified deployment because no separate optical transceivers are required. Its short 0.5 m length minimizes signal loss and crosstalk in dense rack environments while maintaining consistent throughput for latency-sensitive applications. The cable's form factor fits SFP28 ports and is compatible with equipment that supports SFP28 direct-attach copper links, enabling cost-effective, space-saving cabling for short interconnects.
Suitable for
 Top-of-rack (ToR) switch to server connections in data centers
 Switch-to-switch links within the same rack or adjacent racks
 High-density networking panels and server blade interconnects
 Latency-sensitive applications that benefit from copper DAC links
Key specifications
 Connector type: SFP28 to SFP28
 Cable type: Passive direct attach copper
 Nominal length: 0.5 m
 Data rate: 25 Gigabit Ethernet (25GbE)
 Typical use: Short-reach, intra-rack interconnects
 Power profile: Low power consumption due to passive design
How to use
To install, insert each SFP28 connector into the corresponding SFP28 port on your switch, server, or network device until the latch engages. Verify that both endpoints support passive SFP28 DAC links and that port settings match the desired 25GbE configuration. No additional transceivers or fiber patching are required. For cable removal, depress the connector latch and pull the cable straight out to avoid stressing the port.
Usage recommendations
Use this 0.5 m passive DAC for short intra-rack connections where reliable 25GbE bandwidth and low latency are required. Avoid routing the cable through hot or obstructed airflow paths for optimal thermal behavior and keep the cable clear of sharp bends; maintain gentle bend radii to preserve signal integrity.
