Lenovo BCM57454 4x 25GbE SFP28 Adapter | Enterprise Fiber

Add more bandwidth where it matters most: at the server edge. The BCM57454 4X 25GBE SFP28 is built for environments that need more throughput than 10 GbE can deliver, without moving all the way to the cost and cabling profile of 100 GbE. With four 25 GbE SFP28 ports, this adapter supports dense connectivity for virtualization hosts, storage servers, and application clusters that generate steady east-west traffic. The port mix gives architects flexibility in how they segment workloads, aggregate links, and align server networking with the rest of the fabric. This is the kind of adapter chosen when performance needs to scale, but infrastructure teams still want a measured step up in cost and complexity. Broadcom BCM57454 silicon is a proven fit for enterprise server networking, and Lenovo integration helps keep the deployment aligned with standard platform support. For teams refreshing aging 1 GbE or 10 GbE infrastructure, this adapter creates a clear upgrade path: more bandwidth, better concurrency, and a cleaner foundation for modern workloads. It is a strong choice when the network must keep pace with compute without overbuilding the fabric.
