Designed for high-speed 25GbE/32Gb/s interfaces that use SFP28 ports, it provides a low-latency, energy-efficient wired connection between switches, servers or NICs in racks and short-reach data center links. No external power or transceivers required, suitable for cost-effective short-distance interconnects.

## Long description

CBO SFP28-DAC-2M is a 2 meter passive Direct Attach Copper (DAC) cable with SFP28 connectors on both ends, designed for short-reach interconnects in rack and data centre environments. The cable supports 25 GbE and 32 Gb/s interfaces that use SFP28 ports and provides a low-latency, energy-efficient wired link between switches, servers or network interface cards. As a passive assembly, it requires no external power or optical transceivers, offering a simple and cost-effective option for point-to-point connections within the same rack or adjacent racks.
Advantages
The passive copper construction delivers low latency and predictable performance for short-distance links while consuming no additional power for active components. Integrated SFP28 connectors reduce the number of components to install and eliminate the need for separate transceivers, lowering both capital and operational expenses. The fixed 2 m length simplifies cable management in rack deployments and reduces signal loss compared with longer copper runs or unsuitable cable types.
Suitable for
25 Gigabit Ethernet server-to-switch connections
High-speed inter-switch links within a rack or between adjacent racks
Direct connections between NICs and top-of-rack switches
Short-reach storage and compute clusters requiring low-latency links
Key specifications
Connector type: SFP28 to SFP28
Cable type: Passive copper Direct Attach Cable
Nominal data rate: suitable for 25 GbE and compatible 32 Gb/s interfaces
Length: 2 metres
Typical use: short-reach, rack-level interconnects
How to use
Inspect both SFP28 ports on the devices to confirm compatibility and ensure ports are clean and free of debris. Align each SFP28 connector with the device port and insert until the latch engages. Verify link status through the device management interface or LEDs; no additional configuration is required beyond standard port setup. For safe removal, use the connector latch to disengage and pull the cable straight out to avoid stressing the connector or port.
Usage recommendations
Use the cable for short-distance connections within the same rack or between adjacent racks only; avoid using passive DACs for longer links. Maintain bend radii according to manufacturer guidance, avoid kinking, and keep the cable away from sources of electromagnetic interference to preserve signal integrity and performance.
