LWO-DAC-SFP28: 25 Gigabit in the Fast Lane
10 Gigabit was yesterday. Modern servers, NAS systems, and switches increasingly rely on the 25 Gigabit standard (SFP28). Why? Because it transmits 2.5 times the amount of data with the same physical size as SFP+.
Our SFP28 DAC Cables are the easiest way to unlock this performance. They connect two SFP28 ports directly together – without expensive fiber optic modules.
Why 25G instead of 10G?
Especially if you use fast NVMe SSDs in your servers or run virtualization, 10G quickly becomes a bottleneck. 25G offers you massively more reserves here. Since SFP28 is mechanically backward compatible with SFP+, it is the future-proof standard for your rack.
The Right Length for Every Purpose
- 0.5 Meter: Ideal for switch stacking or direct server-to-switch connections in the same slot grid.
- 1.0 Meter: The standard for flexible connections within the rack.
- 3.0 Meter: To bridge larger distances in the cabinet or to the neighboring cabinet.
Technical Advantages
Twinax copper cables are unbeatable at short distances:
- Lowest Latency: Since no complex signal conversion (light/electricity) is required, your systems react faster.
- Energy Efficient: Passive copper consumes hardly any power – saving operating costs and cooling capacity.
- Robust: No fragile optical fibers that can break or get dirty.
