## Summary description

The BlueOptics SFP28-DAC-3M-FR-BL is a 3m SFP28 DAC cable with male connectors on both ends. It is designed for high-speed data transmission in data centers and networking applications. This cable ensures reliable connectivity and optimal performance for your networking needs.

## Long description

The BlueOptics SFP28-DAC-3M-FR-BL is a 3 m SFP28 direct attach copper (DAC) cable with SFP28 male connectors on both ends. Designed for short-reach, high-speed links, this passive twinax cable supports 25GBase-CR electrical transmission and is intended for use in data centers, rack-to-rack connections and other networking environments that accept SFP28 DAC modules. The cable is MSA-compliant and built with 30 AWG twinax conductor specification for reliable signal integrity over a 3 metre distance.
Advantages
This passive SFP28 DAC cable offers low latency, low power consumption and a simple plug-and-play installation without the need for active transceivers. It provides a cost-effective solution for short-distance high-bandwidth connections, with a design focused on mechanical interoperability and long-term availability. The cable’s passive construction reduces potential failure points and supports widespread hardware platforms that accept SFP28 DAC interconnects.
Suitable for
Short-distance interconnects inside racks and between adjacent racks
25 Gbps Ethernet links (25GBase-CR)
High-density switch-to-switch, switch-to-router and switch-to-storage connections
Environments requiring low-latency, low-power copper connections
Key specifications
Length: 3 metres
Connector type: SFP28 male to SFP28 male
Data rate: up to 25 Gbps per link
Cable type: passive twinax copper, 30 AWG
Compliance: SFP28 MSA (electrical and mechanical interoperability)
Colour: black
Typical power consumption: passive (near 0 W for the cable itself)
Weight: 0.08 kg
How to use
Insert each SFP28 connector into the SFP28 port of the devices to be linked, ensuring proper orientation and a secure latch engagement. Use on systems that explicitly support passive SFP28 DAC cables for 25GBase-CR operation. After insertion the link should be negotiated by the connected devices according to their firmware and port settings; verify link status through the device management interface. For reliable performance, avoid sharp bends and maintain the recommended bend radius for twinax cables.
Usage recommendations
Use this cable for short, fixed interconnections within racks or between adjacent racks. Confirm that the target hardware supports passive SFP28 DACs at 25 Gbps and ensure firmware and port settings are compatible before deployment. Store and route the cable to avoid tight bends, mechanical strain, and exposure to excessive heat to prolong service life.
