## Summary description

CBO SFP28-DAC-0.5M is a 0.5 m passive copper direct attach cable (DAC) with SFP28 connectors at both ends. Designed for short-reach 25 Gb/s connections between compatible SFP28 ports in switches, servers or storage devices. Provides a low-latency, cost-effective link for top-of-rack and intra-rack interconnects without needing optical transceivers.

## Long description

CBO SFP28-DAC-0.5M is a 0.5 m passive copper direct attach cable with SFP28 connectors on both ends. It is designed for short-reach 25 Gb/s point-to-point connections between compatible SFP28 ports in switches, servers or storage appliances. The cable provides a low-latency, electrical interconnect option that eliminates the need for separate optical transceivers for short intra-rack and top-of-rack links.
Advantages
The passive copper construction delivers power-efficient, low-latency performance for 25 Gb/s links while maintaining a compact and flexible form factor. With SFP28 connectors at both ends, the cable offers plug-and-play installation into compatible SFP28 ports and reduces hardware complexity and system cost compared with optical solutions for short distances. The fixed 0.5 m length simplifies cable management in dense rack environments and helps maintain signal integrity for short interconnect spans.
Suitable for
 Short-reach 25 Gb/s connections between switches within a rack
 Direct links from servers to top-of-rack switches
 High-density switch-to-switch or switch-to-storage interconnects in data centers
 Cost-sensitive deployments where optical transceivers are unnecessary
Key specifications
 Connector type: SFP28 to SFP28
 Length: 0.5 m (fixed)
 Data rate: up to 25 Gb/s
 Cable medium: passive copper direct attach
 Typical application: short-reach intra-rack and top-of-rack interconnects
How to use
Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on devices that support passive DAC modules. Ensure both devices are powered down or follow hot-swap guidelines provided by the device manufacturer. Verify port configuration and link status in the device management interface after insertion to confirm a proper 25 Gb/s link.
Usage recommendations
Use this passive 0.5 m DAC for short, direct connections inside server racks or between adjacent network devices. Avoid bending the cable sharply and maintain recommended bend radii. For longer runs or environments that require electrical isolation or extended reach, consider active copper DACs or optical transceivers with fiber cables.
