## Long description

The BlueOptics SFP28-DAC-3M-NG-BL is a 3-meter SFP28 Direct Attach Copper (DAC) cable designed for 25G high-speed data links in InfiniBand and Ethernet environments. This passive twinax cable features SFP28-to-SFP28 connectors and 30 AWG copper conductors, offering a short-reach, low-latency connection suitable for rack-to-rack and intra-rack installations in data centers and enterprise networks. The cable is MSA-compliant and intended for use with hardware platforms that support SFP28 passive DACs.
Advantages
The cable provides reliable 25G bandwidth with low power consumption and minimal latency due to its passive twinax design. Being MSA-compliant ensures electrical and mechanical interoperability with a wide range of switches, routers and storage systems that accept SFP28 DAC modules. Construction from high-quality components and industry-standard testing supports long service life and predictable performance for short-distance links.
Suitable for
Short-distance connections between switches and top-of-rack equipment
Direct links between servers and storage systems requiring 25G bandwidth
InfiniBand or 25G Ethernet environments in data centers
Key specifications
Connector type: SFP28 to SFP28
Length: 3 meters
Data rate: up to 25 Gbit/s
Cable type: passive twinax copper, 30 AWG conductors
MSA compliance for SFP28 DAC form factor
Typical applications: Ethernet, FCoE, Fibre Channel, InfiniBand up to 25G
Low power consumption and low latency suitable for short links
How to use
Install the SFP28-DAC-3M-NG-BL by inserting each SFP28 connector into the corresponding SFP28 ports on the two devices to be linked. Ensure both devices explicitly support passive SFP28 DAC cables and that port configurations (speed and protocol) are set to match 25G operation. Avoid excessive bending or strain on the cable; secure routing inside racks with gentle curves and appropriate cable management. No external power or transceivers are required for passive operation.
Usage recommendations
For optimal performance, use this 3 m passive DAC for direct rack-to-rack or within-rack connections where link distance is within the specified range. Verify compatibility with the target hardware vendor's specifications and firmware requirements before deployment. Store and handle the cable to prevent sharp bends and mechanical damage that could affect signal integrity.
