## Summary description

Passive copper Direct Attach Cable (DAC) CBO SFP28-DAC-1M is a 1-meter SFP28-compatible cable designed for short-reach 25Gb/s connections between compatible network equipment. It provides a fixed, low-latency link for switches, routers and servers with SFP28 ports, simplifying rack-level and adjacent-rack interconnects while avoiding optics and reducing power consumption.

## Long description

The SFP28 Passive Copper DAC Cable CBO SFP28-DAC-1M is a 1-meter direct attach copper cable engineered for 25Gb/s links between devices with SFP28 ports. This passive DAC provides a fixed electrical connection that eliminates the need for separate transceivers and optical modules, offering a straightforward solution for short-reach interconnects at rack or adjacent-rack distance. It is intended for use in high-density network environments where low latency, minimal power draw and compact cabling are priorities.
Advantages
This passive copper DAC delivers a dependable 25Gb/s electrical interface with low latency and consistent performance for short-distance connections. Because it is a direct attach cable, the solution reduces component count and operational power compared with active modules or fiber optics. The 1 m length suits common rack and top-of-rack deployments and simplifies cable management while maintaining signal integrity appropriate for switch-to-switch, switch-to-server or server-to-server links.
Suitable for
Top-of-rack and adjacent-rack switch interconnects
High-density server farm connections and blade server links
Short-reach 25Gb/s uplinks and downlinks in data center racks
Low-latency cluster and storage network links
Key specifications
Connector type: SFP28-compatible direct attach copper
Nominal data rate: 25 Gb/s per channel
Cable length: 1 meter
Form factor: Fixed, passive twinax copper assembly
Typical use range: short-reach, rack-level interconnects
Power: passive operation (no external power required)
How to use
Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on network switches, routers or servers until the latch engages. Ensure both devices are powered and configured to support a 25Gb/s electrical link. No additional transceivers or optical modules are required. For best results, route the cable to avoid tight bends and mechanical strain on the connectors; verify link status through device management interfaces and perform standard network testing after installation.
Usage recommendations
Use this passive DAC for short-distance, high-density interconnects where low latency and low power consumption are priorities. Avoid using the cable for longer reaches than intended, and maintain bend radius and connector cleanliness to preserve signal quality.
