Designed for SFP28 ports to provide a short-reach, low-latency 25GbE connection between network switches, servers or NICs.

## Long description

CBO DAC SFP28 BlueLAN CBO SFP28-DAC-3M is a passive 3-meter twinax direct attach cable for SFP28 ports. It provides a low-latency, short-reach 25GbE link suitable for connecting switches, servers and network interface cards in data center and rack-to-rack environments. The fixed-length design offers plug-and-play installation without additional transceivers, delivering a cost- and energy-efficient copper connectivity option for high-density network deployments.
Advantages
The passive twinax construction ensures minimal signal processing and low latency, while the 3 m length balances reach and cable management in rack installations. As a fixed direct attach cable, it eliminates the need for separate transceivers, reducing component count and power consumption. The SFP28 form factor maintains compatibility with standard SFP28 ports and supports a straightforward plug-and-play setup for rapid deployment.
Suitable for
 Short-reach 25GbE connections between switches in a single rack or adjacent racks
 Direct links between servers and network interface cards supporting SFP28
 Top-of-rack and leaf-spine fabrics requiring low-latency copper interconnects
 High-density data center deployments where space and power efficiency are priorities
Key specifications
 Connector type: SFP28 to SFP28
 Length: 3 m
 Type: Passive twinax direct attach cable (DAC)
 Data rate: 25 Gbit/s per lane (25GbE link)
 Cable material: Shielded copper twinax
 Application: Short-reach, rack-to-rack, server-to-switch interconnect
How to use
Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on the devices to be linked. Ensure both devices support passive DACs and are powered off or follow hot-plug guidance from the equipment manufacturer if connecting live. Once seated, the devices should recognize the SFP28 connection automatically; verify link status and configure network settings on the connected equipment as required. Route the cable to avoid sharp bends and maintain appropriate bend radius for twinax copper cabling.
Usage recommendations
Use the cable for short, high-throughput links inside racks or between adjacent racks. Avoid extended outdoor runs or installations requiring active optical transceivers. Maintain cable bend radius and secure routing to prevent mechanical stress, and confirm compatibility with equipment vendor lists for passive SFP28 DACs where available.
