## Summary description

Passive CBO SFP28-DAC-1M is a 1-meter direct-attach copper cable designed for SFP28 ports supporting 25Gb/s links. It provides a low-latency, cost-effective connection between switches, NICs and servers within racks or short data-center runs. The fixed-length cable simplifies deployment, reduces power consumption compared with optical transceivers, and is suitable for high-density 25Gb Ethernet interconnects.

## Long description

Passive CBO SFP28-DAC-1M is a 1 m direct-attach copper cable engineered for SFP28 ports and 25Gb/s links. The fixed-length twinax assembly provides a point-to-point connection between switches, network interface cards and servers for short-reach topologies within racks or between adjacent racks. As a passive direct-attach cable, it requires no additional power for signal conversion and offers a compact, low-latency option for dense 25Gb Ethernet interconnects.
Advantages
The cable delivers predictable, low-latency performance with minimal power consumption compared with optical transceivers. Its one-meter length simplifies rack cabling and reduces clutter while maintaining signal integrity for short runs. The direct-attach form factor eliminates the need for separate transceivers and reduces total component count, which can lower equipment and operational costs in high-density environments.
Suitable for
 Short-reach connections between top-of-rack switches and servers
 Interconnects between adjacent racks in data centres
 High-density 25Gb Ethernet aggregation and leaf-spine fabrics
 Server NIC to switch direct links where 1 m length is sufficient
Key specifications
 Connector type: SFP28 direct-attach twinax
 Cable length: 1 metre
 Data rate: supports up to 25 Gb/s per channel
 Type: passive copper (no active signal conditioning)
 Use case: short-reach, within-rack or adjacent-rack interconnects
How to use
Install the cable by inserting each SFP28 end into the corresponding port on the switch, server or NIC until the connector latch clicks into place. Ensure devices are powered off or follow hot-plug guidelines provided by the equipment manufacturer when connecting or disconnecting. Verify link status and speed through the host or switch management interface after insertion. For reliable operation, route the cable to avoid sharp bends and excessive strain.
Usage recommendations
Use this passive 1 m DAC for short, high-density 25Gb links where power efficiency and minimal latency are priorities. Avoid exceeding manufacturer-recommended bend radius and keep connections within a single rack or between adjacent racks to maintain signal integrity. Confirm SFP28 compatibility with your network equipment before deployment.
