The cable features a durable construction and is ideal for short-distance connections, ensuring minimal latency and maximum performance in your network setup.

## Long description

The BlueOptics FN-CABLE-SFP28-50CM SFP28 DAC 0.5m Blue is a direct attach copper cable engineered for short-reach 25 Gbps connections in data centres and enterprise networks. At 0.5 metres length it links SFP28 ports with minimal signal loss and low latency, offering a compact and power-efficient alternative to active optical transceivers for top-of-rack and switch-to-switch interconnects. The cable’s plug-and-play design requires no additional configuration, making it suitable for dense rack environments and predictable high-speed links.
Advantages
This SFP28 DAC cable delivers consistent 25 Gbps throughput with low power consumption and reduced heat generation compared with active modules. Its robust construction provides reliable mechanical connections and resistance to bending stress typical in server and switch cabling. The short 0.5 m length minimises clutter and helps maintain signal integrity over the intended transmission distance. Compatibility with SFP28 ports ensures straightforward deployment without firmware changes in most standard network setups.
Suitable for
Short-reach connections between switches, servers and NICs at 25 Gbps
Top-of-rack or adjacent-rack interconnects in data centres
High-density rack installations where space and cooling are constrained
Test lab setups requiring reliable, repeatable 25 Gbps links
Key specifications
Interface: SFP28 to SFP28 direct attach copper
Nominal data rate: up to 25 Gbps
Length: 0.5 metres
Cable type: passive DAC (direct attach copper)
Connector orientation: standard SFP28 form factor
Colour: blue
How to use
Ensure both devices support SFP28 interfaces and power down or follow hot-plug guidelines of your equipment when inserting or removing transceivers. Align the SFP28 connectors with the ports and insert until the latch engages; confirm link status via device LEDs or management interface. Use the cable for short point-to-point links; avoid stretching or tightly bending the cable near the connector boots to maintain mechanical reliability and signal integrity.
Usage recommendations
For optimal performance, use this 0.5 m DAC cable only for short-reach connections up to the intended distance. Route cables to minimise sharp bends and avoid running parallel to high-power electrical lines. Verify switch or server compatibility with SFP28 passive DACs in product documentation to prevent interoperability issues.
