## Summary description

Passive copper DAC cable CBO SFP28-DAC-0.5M, 0.5 m length, designed for direct SFP28-to-SFP28 connections. Provides a low-latency, low-power link for 25GbE or compatible SFP28 ports in switches, servers and storage devices. Ideal for short-range interconnects in racks and data centers where a reliable, cost-effective copper connection is required.

## Long description

Passive copper DAC cable CBO SFP28-DAC-0.5M is a 0.5 m direct-attach cable designed for SFP28-to-SFP28 connections. It supports 25GbE and compatible data rates, providing a low-latency, low-power physical link for short-range interconnects inside racks and network equipment. The cable is intended for environments such as data centers and server rooms where compact, reliable copper connections are required between switches, servers and storage devices.
Advantages
This passive DAC cable delivers predictable latency and minimal power consumption compared with active optical transceivers, enabling straightforward point-to-point links at 25GbE speeds. Its fixed 0.5 m length minimizes excess cabling and simplifies cable management in dense rack installations. The cable provides a cost-effective solution for short-distance connections, with broad compatibility with standard SFP28 ports and plug-and-play operation that requires no external power or configuration.
Suitable for
 Short-range connections between SFP28 ports in rack-mounted switches
 Direct server-to-switch interconnects at 25GbE
 Interlinks between storage systems and network appliances inside the same rack
 High-density cabling environments where cable length must be minimized
Key specifications
 Connector type: SFP28 to SFP28 (copper DAC)
 Length: 0.5 m
 Data rate: supports 25GbE and compatible SFP28 data rates
 Power: passive (no external power required)
 Cable medium: twinax copper
 Typical application: short-range, intra-rack interconnects
How to use
Insert each SFP28 connector firmly into the corresponding SFP28 port on the network devices until the latch engages. Ensure both devices are powered and that ports are configured for the same data rate and link settings. No additional configuration or power source is required for the passive DAC cable; the link should be recognized by standard network equipment that accepts SFP28 twinax modules. For best results, verify link status in the device management interface after insertion.
Usage recommendations
Use this 0.5 m passive DAC cable for intra-rack connections and short-distance links where low latency and low power consumption are priorities. Avoid routing the cable near high-heat sources and maintain proper bend radius to prevent mechanical stress. Confirm compatibility with your equipment vendor's supported transceiver list when deploying at scale.
