## Summary description

The BlueOptics SFP28-DAC-3M-MR-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. This cable is ideal for connecting switches, servers, and storage devices in data centers, providing reliable performance and low latency.

## Long description

The BlueOptics SFP28-DAC-3M-MR-BL is a 3 m SFP28 direct attach cable (DAC) with SFP28 male connectors on both ends, designed for high-speed short-distance connections. This passive twinax copper cable supports 25GBase-CR electrical signalling and is MSA-compliant. It is intended for linking switches, servers and storage devices in data centre racks or adjacent racks where a reliable, low-latency 25 Gbit/s connection is required.
Advantages
The cable provides a fixed 3 m link with low latency and low power consumption typical of passive DAC twinax solutions. Compliance with SFP28 MSA ensures mechanical and electrical interoperability with major hardware platforms that support passive 25G DACs. Constructed from quality components and manufactured under controlled processes, the cable is suitable for professional rack-to-rack and intra-rack connectivity and offers predictable performance for Ethernet, FCoE, Fibre Channel and InfiniBand applications up to 25 Gbit/s.
Suitable for
Connecting SFP28 ports on switches within a rack or between adjacent racks
Server to switch direct connections in data centres
Storage system links that require short-reach 25 Gbit/s electrical connections
Applications using Ethernet, FCoE, Fibre Channel or InfiniBand up to 25 Gbit/s
Key specifications
Length: 3 meters
Interface: SFP28 male to SFP28 male
Data rate: up to 25 Gbit/s
Cable type: passive twinax copper (DAC), 30 AWG
Standard compliance: SFP28 MSA
Typical power consumption: very low (passive cable)
How to use
Insert each SFP28 connector into the corresponding SFP28 port on the devices to be linked, ensuring secure seating and that both devices support passive DAC twinax connections. Route the cable to avoid sharp bends and mechanical strain; maintain recommended bend radius for twinax copper. No additional transceivers or power sources are required for passive operation. Verify link status and negotiated speed on connected devices according to their management interface.
Usage recommendations
Use this 3 m DAC for short-range rack and adjacent-rack connections where a reliable 25G electrical link is needed. Confirm device compatibility with passive SFP28 DACs and test the link after installation. For longer distances or optical isolation requirements, consider appropriate optical transceivers and fibre cabling instead.
