## Summary description

CBO SFP28-DAC-2M is a 2-meter passive Direct Attach Copper (DAC) cable with SFP28 connectors designed for 25GbE links. It provides a fixed, low-latency electrical connection between SFP28 ports on switches, NICs or servers, suitable for short-reach interconnects in racks and data center topologies. Benefits include simple plug-and-play installation, reduced power consumption compared with active optics, and cost-effective high-speed connectivity.

## Long description

CBO SFP28-DAC-2M is a 2-meter passive Direct Attach Copper cable with SFP28 connectors engineered for 25GbE links. It delivers a fixed electrical connection between SFP28 ports on switches, network interface cards and servers, intended for short-reach interconnects within racks and data center topologies. The cable provides low latency and stable signal integrity for high-speed connections while avoiding the need for separate transceivers.
Advantages
The passive DAC cable offers plug-and-play installation with no additional configuration or power required. Compared with active optical solutions, it reduces power consumption and overall link cost while preserving 25GbE performance. Its fixed-cable design ensures predictable latency and consistent throughput for tightly coupled equipment in the same rack or adjacent racks.
Suitable for
 Short-reach 25GbE links between switches and servers
 Top-of-rack and end-of-row network interconnects
 Direct connections between NICs and storage or compute nodes
 Environments that prioritize low latency and energy-efficient cabling
Key specifications
 Connector type: SFP28 on both ends
 Cable type: Passive Direct Attach Copper (DAC)
 Data rate: 25 Gigabit Ethernet
 Length: 2 meters
 Latency: fixed, low-latency electrical link suitable for short distances
 Installation: plug-and-play, no external power required
How to use
Insert each SFP28 connector into compatible SFP28 ports on switches, NICs or servers until the latch engages. Ensure both devices support 25GbE and that port settings match required link parameters. No additional drivers or power sources are required for the passive DAC; once both ends are seated correctly, the link should be established automatically and appear in device management interfaces.
Usage recommendations
Use the cable for short intra-rack or adjacent-rack connections where a fixed, cost-effective 25GbE link is needed. Avoid excessive bending near the connector ends and maintain recommended rack routing to prevent mechanical stress. For longer distances or when optical isolation is required, consider optical transceivers and fiber cabling instead.
