Lenovo 20M 100G QSFP28 Active Optical Cable

Overview

The Lenovo 7Z57A03550 is an active optical cable designed to deliver reliable 100 GbE connectivity over a 20-meter distance. It uses QSFP28 connectors with integrated transceivers, eliminating the need for separate optical modules. This cable is ideal for data centers requiring high-speed, long-reach connections between servers, switches, and storage systems, especially in environments where electromagnetic interference makes copper cables less effective.

Its optical design ensures consistent signal quality across rack-to-rack or inter-row distances, making it a practical choice for network uplinks, aggregation, and storage interconnects. The fixed length simplifies cable management and planning in complex data center layouts.

Connectivity and compatibility

This cable is compatible with networking devices that support QSFP28 interfaces, commonly found in modern servers, switches, and storage arrays. Its optical design allows it to bypass the limitations of copper cabling, making it suitable for environments where electromagnetic interference is a concern. The fixed 20-meter length fits well in typical data center rack layouts, supporting point-to-point connections across aisles or between rows.

Ideal uses and environments

The Lenovo 7Z57A03550 is well suited to data centers that require stable 100 GbE links over medium distances. It works effectively for server uplinks to switches, switch aggregation, and storage network connections where copper cables fall short due to distance or interference. This cable is a strong choice for new data center builds, expansions, or refresh projects that demand predictable high-speed connectivity with minimal installation complexity.
