Lenovo 4X97B01312 10 m 400G QSFP112 AOC | Active Optical, Enterprise

When 400G links need more reach than copper can comfortably provide, an active optical cable keeps the design simple. Lenovo’s 10 m 400G QSFP112 AOC is built for short-to-medium distance interconnects that demand 400G throughput without the added complexity of separate transceivers and fiber patch cords. The active optical design supports cleaner routing across racks, cabinets, and adjacent rows while preserving the port compatibility expected in modern 400G environments. For teams standardizing on QSFP112 infrastructure, an AOC can reduce installation steps and help maintain a tidy physical layer where airflow and serviceability matter. This model is well suited to dense data center builds where copper DAC reach is not enough, but a full optical breakout architecture would add unnecessary parts and handling. The 10 m length gives practical flexibility for structured cabling between equipment locations, while the integrated optical assembly keeps the deployment compact. For organizations that value predictable 400G connectivity with less cabling overhead, this Lenovo AOC is a disciplined choice.
