Lenovo BCM57454 4x 10/25Gb SFP28 Adapter | Fiber, Enterprise

Increase server-side network capacity with a 4-port SFP28 adapter built for 10 Gb and 25 Gb fiber environments. The BCM57454 is a practical choice when you need higher throughput without filling the chassis with single-port cards. That density matters in modern racks where every slot, lane, and cable run has a cost. For enterprise teams, this class of adapter is about more than raw speed. It supports cleaner consolidation, more predictable scaling, and a better balance between performance and physical footprint. Instead of adding complexity to the rack, it gives you a compact way to expand bandwidth where it is needed most. This model is well suited to server refreshes, storage-heavy workloads, and network designs that depend on SFP28 optics. It is the kind of component that earns its place by reducing bottlenecks and preserving expansion headroom for the next phase of growth.
