## Summary description

The BlueOptics SFP28-DAC-3M-LO-BL is a 3-meter SFP28 DAC cable designed for high-speed data transmission. It features male connectors on both ends, ensuring compatibility with SFP28 ports. Ideal for connecting switches, servers, and storage devices in data centers. This cable provides reliable performance and low latency for InfiniBand and fibre optic applications.

## Long description

The BlueOptics SFP28-DAC-3M-LO-BL is a 3 m SFP28 direct attach (DAC) twinax cable with SFP28 male connectors on both ends. Designed for short-reach, high-speed connections in racks and between adjacent racks, this passive 25G twinax copper cable supports 25GBase-CR electrical transmission and is intended for use with SFP28 ports on switches, servers and storage devices. The cable is MSA-compliant and built to industry standards for compatibility with major hardware platforms that support SFP28 DAC links.
Advantages
This SFP28 DAC cable provides low-latency, low-power connectivity suitable for short-distance links. As a passive twinax solution, it does not require active electronics in the cable, which reduces power consumption and potential failure points. The 3 m length is suitable for rack-to-rack or within-rack connections, and the MSA-compliant design ensures interoperability with a wide range of SFP28-capable equipment. Materials and construction follow industrial quality practices to deliver consistent electrical performance for Ethernet, FCoE, Fibre Channel and InfiniBand applications up to 25 Gbit/s.
Suitable for
 Connecting top-of-rack switches to servers and storage within the same rack
 Linking adjacent racks in data centers for short-reach 25G links
 Low-latency interconnects for storage area networks and compute clusters
 Environments that require MSA-compliant SFP28 direct attach connections
Key specifications
 Connector type: SFP28 male to SFP28 male
 Length: 3 metres
 Transmission rate: up to 25 Gbit/s
 Cable type: passive twinax copper (DAC)
 Wire gauge: 30 AWG
 Standards compliance: SFP28 MSA, supports 25GBase-CR electrical interface
 Typical power consumption: passive (near 0 W in-cable)
How to use
Verify that both devices have SFP28 ports that support passive DAC twinax cables. With power off or per your equipment vendor’s hot-plug guidance, insert one SFP28 connector into each SFP28 port until the latch clicks. Ensure the cable is routed without sharp bends and that the 3 m length matches the intended rack layout. After insertion, confirm link status on both devices and verify negotiated speed (25 Gbit/s) and protocol compatibility for Ethernet, FCoE, Fibre Channel or InfiniBand as required.
Usage recommendations
Use the cable for short-range connections (within a rack or between adjacent racks) and avoid exposure to excessive mechanical stress or extreme temperatures. For best results, follow your hardware vendor’s guidelines for passive DAC usage and test the link in your environment to confirm compatibility and performance prior to deployment in critical systems.
