Lightwin LWO-DAC-SFP28-0.5M | 0.5m SFP28 DAC Cable 25Gbps

High-speed stacking without cable clutter: This 0.5 meter SFP28 DAC cable delivers full 25 Gigabit over the shortest distance. It is specifically designed to connect devices mounted directly on top of each other in the rack (e.g., server to Top-of-Rack switch). With a length of just 50 cm, you avoid unnecessary loops and ensure optimal airflow in the server cabinet. The ideal, cost-efficient solution for modern data centers and NVMe storage clusters.

⚠️ Important Compatibility Note:
This DAC cable is designed for 25 Gigabit (SFP28) ports. It uses the same form factor as SFP+ but requires SFP28 hardware for full performance. It is not suitable for old 1 Gigabit (SFP) ports.

Highlights

  • 25G Stacking: Perfect 50 cm length for adjacent devices.
  • Clean Setup: No cable clutter, optimal airflow in the rack.
  • Next-Gen Speed: 25 Gbps bandwidth (25GBASE-CR).
  • Low Latency: Minimal delay for fast databases & storage.
  • Plug & Play: Plug in, done, enjoy 25G.

0.5m SFP28: The Ultra-Short Turbo

If you want to connect modern servers with 25G interfaces (SFP28) directly to a switch located right above, a long cable just gets in the way.
The 0.5 meter version is the cleanest solution for this scenario. It creates a short arc from port to port. This not only looks professional but also prevents heat buildup since no cable bundles block the fans.

Ideal for NVMe & Virtualization

Passive copper cables show their strength especially over short distances: they have extremely low latency. This is crucial when connecting fast NVMe storage or high-frequency trading servers. With this cable, the performance reaches the network without braking.
