## Summary description

The BlueOptics SFP28-DAC-3M is a 3-meter SFP28 DAC cable with male connectors on both ends. It is designed for high-speed data transfer in InfiniBand and fibre optic applications, ensuring reliable connectivity.

## Long description

The BlueOptics SFP28-DAC-3M is a 3‑metre direct attach copper cable with SFP28 male connectors on both ends, designed for short‑reach 25 Gbps links in data centre and rack environments. As a passive twinax assembly, it provides a compact, low‑latency electrical connection for switches, routers, storage systems and other hardware platforms that support SFP28 DAC interfaces.
Advantages
This SFP28 DAC cable offers a simple, low‑power and low‑latency solution for 25G short‑reach connections. Its passive twinax design eliminates the need for active components in the cable, reducing power consumption and potential failure points. The cable is MSA‑compliant and built to industry wiring standards for reliable interoperability with major vendor platforms that accept SFP28 passive DACs.
Suitable for
Short‑reach interconnects within racks and between adjacent racks
25G Ethernet, FCoE and InfiniBand links up to 3 m
Connections between switches, top‑of‑rack devices and storage arrays
Key specifications
Length: 3 metres
Interface: SFP28 male to SFP28 male
Performance: supports up to 25 Gbps per lane for short‑reach electrical links
Cable type: passive twinax copper (30 AWG conductors)
Colour: black
Typical weight: 0.08 kg
How to use
Insert each SFP28 connector into the corresponding SFP28 port on your devices until the latch engages. Use this cable for direct electrical links where both connected devices officially support passive SFP28 DACs. Ensure firmware and port settings on the connected hardware are configured for 25G operation and verify link status through your device management tools. Avoid excessive bending and mechanical strain on the cable and connectors during installation.
Usage recommendations
For reliable operation, use the cable within racks and between adjacent racks at distances up to 3 metres, keep bend radius within manufacturer guidance, and verify compatibility with the host hardware. Passive SFP28 DACs depend on device support for passive assemblies; consult your equipment documentation before deployment.
