Lenovo 7Z57A03555 20 m QSFP28 to 4xSFP28 AOC | Breakout Fiber

Turn a single 100G port into four 25G links with the Lenovo DCG Server Options 20 m 100G to 4x25G Breakout Active Optical Cable. This QSFP28-to-4xSFP28 active optical cable is built for environments that need to distribute bandwidth efficiently without adding unnecessary cable mass or limiting placement options. The 20 m reach gives architects room to separate equipment across racks while keeping the signal path direct. That matters in modern data centers where uplink aggregation, leaf-spine layouts, and server fan-out designs depend on predictable connectivity and disciplined cable management. Compared with lower-cost passive alternatives, this breakout AOC is better suited to longer runs and higher-density deployments where port planning and airflow matter. It is a practical choice for teams standardizing on 100G uplinks but needing four 25G endpoints for servers, storage, or access-layer devices. For Lenovo infrastructure, it supports a cleaner physical layout and a more controlled migration path as port speeds increase.
