Description

Lenovo 7Z57A04256 Active Optical Cable

Overview

The Lenovo 7Z57A04256 is a 1-meter active optical cable (AOC) designed for high-speed data transmission. It features QSFP+ connectors on both ends, enabling 40 Gigabit Ethernet connectivity between network devices. This cable is ideal for data center environments requiring robust, high-bandwidth interconnects for servers, switches, and storage arrays, ensuring minimal latency and maximum throughput for demanding applications.

Compatibility

This QSFP+ AOC is engineered for use with Lenovo ThinkSystem servers and network switches. It is compatible with any equipment utilizing standard QSFP+ ports for 40GbE connections, ensuring interoperability within a Lenovo infrastructure or with other compliant networking hardware. Verify your specific device's QSFP+ port specifications for direct compatibility.

Installation Notes

As an active optical cable, it requires no external power source. The QSFP+ connectors are keyed and designed for a secure, plug-and-play installation into compatible ports. Ensure the environment is free from excessive dust or moisture to maintain connection integrity. The 1-meter length is suitable for in-rack or adjacent-rack connections, minimizing cable clutter and signal degradation.
