Lenovo 4Z57A10844 100G AOC
Overview
The Lenovo 4Z57A10844 is a 1-meter 100Gbps QSFP28 active optical cable (AOC). It provides a direct, high-bandwidth connection between network devices such as servers, switches, and storage arrays. This cable is designed for data center environments where consistent, low-latency 100GbE connectivity is critical for applications like high-performance computing, AI/ML workloads, and large-scale data transfer. Its active nature means it includes signal conditioning electronics within the connectors, enabling longer reach and potentially lower power consumption compared to passive copper cables over the same distance.
Compatibility
This 100G QSFP28 AOC is designed for use with Lenovo ThinkSystem servers and network switches that feature QSFP28 ports. Specifically, it is compatible with systems supporting 100Gb Ethernet connections, including but not limited to the SR950 server (Xeon Gen 1) when equipped with compatible Mellanox or Nvidia ConnectX-6 Dx 100GbE QSFP56 adapters (e.g., 4XC7A99190, 4XC7A08248) or other QSFP28-enabled network infrastructure. It ensures plug-and-play connectivity for high-speed data links.
Installation Notes
Ensure the QSFP28 ports on both the server and the connected device are clean and free of debris before insertion. The cable's connectors are keyed to prevent incorrect insertion. For optimal performance and signal integrity, avoid sharp bends or excessive tension on the cable. The active optical nature of this cable means it requires no external power source beyond what the host ports provide.
