## Summary description

CBO SFP28-DAC-3M is a 3-meter passive direct attach copper (DAC) cable designed for SFP28 ports. It provides a low-latency, cost-effective connection for 25GbE links in switches, servers and storage systems. The cable delivers reliable short-reach connectivity with minimal power consumption and straightforward plug-and-play installation.

## Long description

CBO SFP28-DAC-3M is a 3-meter passive Direct Attach Copper (DAC) cable engineered for SFP28 ports. It provides a low-latency, short-reach copper connection for 25GbE links between switches, servers and storage systems. The cable requires no additional transceivers or configuration and supports straightforward plug-and-play installation, offering a cost-effective option where fiber is not required and distances are within the cable’s reach.
Advantages
The passive DAC design keeps power consumption low and eliminates the need for separate optical modules, reducing overall deployment cost. Its fixed 3 m length simplifies cable management in rack environments and ensures consistent electrical performance for 25GbE links. The cable’s construction provides reliable signal integrity for short interconnects and stable, deterministic latency suited to high-throughput environments.
Suitable for
 Connecting top-of-rack switches to servers at 25GbE speeds
 Short-distance links between storage arrays and compute nodes
 High-density data center deployments requiring low-latency interconnects
 Lab and test environments where cost-effective copper interconnects are preferred
Key specifications
 Cable type: Passive Direct Attach Copper (DAC)
 Connector type: SFP28 on both ends
 Length: 3 meters
 Supported link speed: 25 Gigabit Ethernet (25GbE)
 Power consumption: passive (no active electronics in-line)
 Cable application: short-reach, rack-to-rack and within-rack connections
How to use
Insert each SFP28 connector into compatible SFP28 ports on your networking devices until the latch engages. Ensure devices are powered and configured for 25GbE operation where necessary; most devices will negotiate the link automatically with plug-and-play operation. Route the cable to avoid tight bends and physical stress, and verify link status indicators on both endpoints. If a link does not come up, check port compatibility and firmware requirements on connected devices.
Usage recommendations
Use the cable for short-distance connections within racks or between adjacent racks. Avoid exposing the cable to sharp bends or mechanical strain and keep it away from sources of electromagnetic interference where possible. For longer distances or environments requiring optical isolation, consider using fiber-optic transceivers instead.
