## Summary description

CBO SFP28-DAC-2M is a 2-meter passive DAC (Direct Attach Copper) cable with SFP28 connectors designed for 25Gbps network links. It provides a direct twinax copper connection between SFP28 ports on switches, servers or NICs, offering low-latency, cost-effective short-reach connectivity for data centers and rack-to-rack links.

## Long description

CBO SFP28-DAC-2M is a 2-meter passive DAC (Direct Attach Copper) cable with SFP28 connectors engineered for 25Gbps network links. The twinax copper assembly provides a direct electrical connection between SFP28 ports on switches, servers or network interface cards (NICs), enabling short-reach, low-latency links suitable for data center topologies and rack-to-rack interconnects. The cable is intended for environments where cost-efficient, reliable 25Gbps connectivity is required without the need for optical transceivers.
Advantages
The passive twinax construction delivers low power consumption and minimal signal processing, resulting in reduced latency compared with active or optical alternatives. With fixed SFP28 form-factor connectors and a compact, flexible jacket, the cable supports high-density installations and straightforward plug-and-play operation. Its 2 m length is optimized for short links within racks or between adjacent racks, providing predictable electrical performance for 25Gbps links.
Suitable for
 Short-reach links between top-of-rack switches and servers
 Interconnects in data center racks and adjacent rack connections
 High-density switch to switch uplinks where 25Gbps bandwidth is required
 Systems and NICs with SFP28 ports supporting copper DACs
Key specifications
 Connector type: SFP28 male on both ends
 Length: 2 meters
 Data rate: up to 25 Gbps per link
 Cable type: passive twinax copper
 Use case: short-reach, direct attach copper interconnect
 Form factor: SFP28 compatible for high-density ports
How to use
Insert each SFP28 connector into the corresponding SFP28 port on the two devices to be linked, ensuring the latch engages to secure the connection. Confirm both devices are configured for 25Gbps operation and that the ports accept passive DAC modules. No additional transceivers or fiber patching is required. For best signal integrity, avoid sharp bends and maintain the cable’s minimum bend radius during installation. After connection, verify link status and throughput using the devices’ management interfaces.
Usage recommendations
Use this 2 m passive SFP28 twinax cable for short-distance, cost-sensitive 25Gbps connections inside racks or between adjacent racks. Ensure compatibility with your switch or NIC vendor’s supported list for passive DACs and follow standard ESD handling practices during installation.
