## Summary description

The BlueOptics UACC-DAC-SFP28-0.5M-BL is a high-quality InfiniBand/fibre optic cable designed for efficient data transmission. With a length of 0.5 meters and Male/Male SFP28 connectors, it ensures reliable connectivity for high-speed networking applications. Ideal for data centers and enterprise networks, this cable offers durability and performance for demanding environments.

## Long description

The BlueOptics UACC-DAC-SFP28-0.5M-BL is a 0.5 meter Direct Attach Cable (DAC) with SFP28 Male-to-Male connectors, designed for short-distance high-speed links in data centers and enterprise racks. This passive 25GBase-CR twinax copper cable conforms to SFP28/MSA form factors and uses 30 AWG conductors to carry electrical signals for Ethernet, FCoE, Fibre Channel and InfiniBand applications up to 25 Gbit/s over a half-meter span. The cable is intended for reliable interconnections between switches, routers, storage systems and other network hardware that support SFP28 passive DACs.
Advantages
The cable offers low-latency, low-power passive operation and a compact twinax design suitable for dense rack deployments. Passive construction eliminates the need for active electronics in the cable, reducing power consumption and potential points of failure. Manufacturing to industry MSA standards and the use of high-quality components contribute to long operational life and consistent compatibility with major hardware platforms that accept SFP28 passive DACs.
Suitable for
 Short-range 25 Gbit/s links in data center racks
 Inter-shelf and adjacent-rack connections between switches and routers
 Direct connections to storage systems and host adapters supporting SFP28
 Environments requiring low-latency, low-power physical links
Key specifications
 Cable type: Passive twinax copper (DAC)
 Connector type: SFP28 Male to SFP28 Male
 Data rate: Up to 25 Gbit/s
 Length: 0.5 meter
 Wire gauge: 30 AWG
 Standards: SFP28/MSA compliant
How to use
Install the BlueOptics UACC-DAC-SFP28-0.5M-BL by plugging each SFP28 connector into compatible SFP28 ports on the two devices to be linked. Ensure both devices support passive DAC SFP28 modules and that firmware or vendor restrictions do not block third-party passive cables. Route the cable cleanly to avoid sharp bends and mechanical strain; maintain recommended bend radius for twinax cables. No external power or transceiver configuration is required on the cable itself.
Usage recommendations
Confirm hardware compatibility with the device vendor and check port settings or firmware requirements before deployment. For reliable long-term operation, avoid tight bends, secure the cable to prevent movement in high-vibration areas, and perform link tests after installation to verify 25G connectivity.
