## Summary description

CBO SFP28-DAC-0.5M-HU-BL is a 0.5 m direct attach copper (DAC) cable with SFP28 Male-to-Male connectors supporting 25 Gbit/s data rate. Designed for short-reach interconnects between compatible SFP28 ports in switches, NICs and servers. Provides low-latency, power-efficient connectivity for data center top-of-rack and server-to-switch links.

## Long description

BlueOptics Direct Attach Copper Cable CBO SFP28-DAC-0.5M-HU-BL is a 0.5 m passive DAC solution with SFP28 male-to-male connectors designed for 25 Gbit/s links. It provides a short-reach, low-latency copper connection for compatible SFP28 ports in switches, network interface cards and servers. The compact 0.5 metre length is suited to top-of-rack and server-to-switch interconnects where a fixed, low-power cabling option is required.
Advantages
The cable delivers a stable 25 Gbit/s data rate with minimal latency and reduced power consumption compared with optical transceivers. Its direct attach copper design eliminates the need for separate transceivers, simplifying installation and reducing component count. The male-to-male SFP28 connectors ensure hot-pluggable compatibility with standard SFP28 ports and a short, fixed length helps maintain tidy cable management in dense rack environments.
Suitable for
Top-of-rack switch to server uplinks
Server-to-switch connections within the same rack
Short-reach data center interconnects requiring 25 Gbit/s throughput
Environments prioritising low latency and energy efficiency
Key specifications
Connector type: SFP28 male-to-male
Length: 0.5 m (fixed)
Data rate: 25 Gbit/s
Media: Direct attach copper (passive)
Typical use: Short-reach interconnects for racks and server rooms
How to use
Insert each SFP28 connector into the corresponding SFP28 port on the devices to be connected, ensuring the latch engages for a secure mechanical connection. No additional configuration is required at the cable level; the connected devices should detect the physical link and negotiate the appropriate link parameters. For best performance, use the cable between devices located within the same rack or adjacent racks, avoiding excessive bending of the cable near the connector ends.
Usage recommendations
Handle the cable by the connector housings when plugging or unplugging and maintain the recommended bend radius for copper DACs. Use in environments with compatible SFP28 ports and verify device compatibility lists if necessary. For deployments requiring longer reach or optical isolation, consider optical transceivers and fiber cabling instead.
