## Long description

The Copper DAC SFP28 cable CBO SFP28-DAC-1M is a 1 meter passive direct-attach copper cable engineered for 25Gb/s SFP28-compatible network ports. It provides a short-reach electrical connection between switches, routers or network interface cards, enabling low-latency, energy-efficient links in high-density rack installations. This passive SFP28 direct attach solution is intended for environments where reliable, cost-effective interconnects are required without the complexity of optical transceivers.
Advantages
This passive 1 m SFP28 DAC delivers reduced power consumption compared with optical modules, while maintaining low latency and predictable signal integrity for short-distance links. The fixed-length copper assembly simplifies cabling design in dense rack setups and eliminates the need for separate fiber transceivers and patch cords. Its direct-attach form factor offers straightforward installation and reliable electrical performance suited to server-to-switch and switch-to-switch connections.
Suitable for
 Short-reach connections between SFP28 ports in the same rack or adjacent racks
 High-density data center top-of-rack and end-of-row cabling
 Direct connections between servers, switches and network interface cards supporting 25Gb/s
 Environments where lower power and simplified infrastructure are priorities
Key specifications
 Connector type: SFP28 to SFP28 (direct attach copper)
 Length: 1 meter (fixed)
 Data rate: up to 25 Gb/s per lane
 Passive design: no active electronics or power required in the cable
 Typical applications: short-reach server and switch interconnects in racks
 Form factor: low-profile SFP28 compatible
How to use
Install the passive SFP28 DAC by inserting each SFP28 connector into the corresponding SFP28 port on the network devices until the latch clicks. Verify that both devices support passive DAC attachments and are configured for 25Gb/s operation. No external power or configuration of the cable is required. For hot-pluggable environments, insert or remove the cable with the devices powered according to the equipment manufacturer’s guidance to avoid port or device issues.
Usage recommendations
For optimal performance, use this 1 m copper DAC for connections within the same rack or adjacent racks and avoid extended runs beyond the recommended short-reach distance. Ensure device compatibility with passive SFP28 DACs, keep the cable free from sharp bends and physical stress, and maintain proper airflow in high-density installations.
