## Summary description

The BlueOptics SFP28-DAC-3M-AT-BL is a 3-meter SFP28 DAC cable with male connectors on both ends. It is designed for high-speed data transmission in data centers and networking environments, ensuring reliable connectivity and performance.

## Long description

The BlueOptics SFP28-DAC-3M-AT-BL is a 3 meter SFP28 direct attach copper (DAC) cable with SFP28 male connectors on both ends. Designed for short-reach, high-speed links in data centers and network racks, the cable supports 25GBase-CR electrical signalling and is MSA-compliant for interoperability with compatible hardware platforms. The cable is a passive twinax copper assembly suitable for connecting switches, routers, storage systems and other SFP28-capable equipment across adjacent units or within racks.
Advantages
The passive twinax design provides low latency and low power consumption, since no active electronics are required in the cable. MSA compliance and industry-grade components ensure compatibility and stable operation across supported platforms. The 3 m length is appropriate for intra-rack and adjacent-rack connections and offers a cost-effective alternative to active modules or fiber for short-distance links.
Suitable for
Short-reach 25 Gbps links between SFP28 ports in the same rack or adjacent racks
High-density switch-to-switch connections in data centers
Server-to-switch or storage-to-switch electrical connections
Environments requiring low-latency, low-power interconnects
Key specifications
Connector type: SFP28 male to SFP28 male
Cable type: Passive twinax copper (DAC), 30 AWG
Nominal length: 3 meters
Supported data rate: up to 25 Gbps per link (25GBase-CR)
Compliance: MSA SFP28 electrical and mechanical compatibility
Typical use: intra-rack and adjacent-rack short-distance electrical connections
Weight (approx.): 0.08 kg
Product colour: Black
How to use
Install the cable by inserting each SFP28 connector into compatible SFP28 ports on the devices to be linked, ensuring the latch engages. No external power or configuration is required for passive operation; link settings are controlled by the connected hardware. Verify that the host devices officially support passive SFP28 DAC cables and set link parameters (speed/duplex) according to the switch or server documentation. For best results, avoid sharp bends and maintain the recommended bend radius for twinax cables.
Usage recommendations
Use this 3 m SFP28 DAC for short-distance electrical interconnects where 25G performance is needed and fiber is unnecessary. Confirm compatibility with your hardware vendor and test the link after installation. Store and route the cable to avoid tight bends, mechanical strain, and exposure to liquids or excessive heat to maintain long-term reliability.
