## Summary description

The BlueOptics SFP28-DAC-3M-NK-BL is a 3m SFP28 DAC cable designed for high-speed data transmission. It features male connectors on both ends, ensuring a reliable connection for networking applications. Ideal for data centers and high-performance computing environments.

## Long description

The BlueOptics SFP28-DAC-3M-NK-BL is a 3 m passive SFP28 direct attach cable (DAC) designed for short-range 25G data links. It has SFP28 male connectors on both ends and a twinax copper construction suitable for use inside racks or between adjacent racks. The cable follows SFP28 DAC MSA conventions and supports common protocols such as Ethernet, Fibre Channel over Ethernet (FCoE) and InfiniBand at speeds up to 25 Gbit/s over a 3 meter distance.
Advantages
This SFP28 DAC cable offers low latency and low power consumption typical for passive twinax copper assemblies. Its fixed 3 m length and SFP28-to-SFP28 male connectors provide a compact, plug-and-play connection without additional transceivers. The cable is built to meet MSA electrical and mechanical specifications and is compatible with major networking hardware platforms that support SFP28 DACs.
Suitable for
Short-range rack-to-rack or in-rack high-speed connections
25G Ethernet links and aggregation ports
FCoE and InfiniBand connections within server and storage environments
Switch-to-switch or switch-to-server direct connections
Key specifications

Weight (approx.): 0.08 kg
How to use
Install the BlueOptics SFP28-DAC-3M-NK-BL by inserting each SFP28 connector into supported SFP28 ports on compatible switches, routers, servers or storage devices. Ensure the connected devices support passive SFP28 DACs and the target data rate. Handle the cable by the connector housings when plugging or unplugging and avoid sharp bends; maintain the recommended bend radius to prevent mechanical stress. No additional transceivers or power sources are required for passive operation.
Usage recommendations
Verify firmware and hardware compatibility with your networking equipment before deployment and, where possible, test the cable in a non-production environment. Use the 3 m passive DAC for short-distance links inside racks or between adjacent racks; for longer reaches, consider active optical or active copper solutions. Store the cable coiled without tight bends and keep connectors covered until installation to avoid contamination.
