Description
The Lenovo 01KN821 is a high-performance QSFP+ transceiver module engineered to deliver 40 Gigabit Ethernet connectivity over single-mode fiber optic infrastructure. The QSFP+ form factor is designed for higher density and bandwidth compared to SFP+ modules, making it suitable for demanding network applications. This module is hot-pluggable, allowing for seamless integration and replacement within compatible Lenovo networking equipment without requiring system downtime. This transceiver operates with single-mode fiber, which is essential for achieving extended transmission distances. While the exact reach is not specified in the title, QSFP+ SMF transceivers typically support distances ranging from 10 km up to 40 km or more, depending on the specific variant. The LC connector is the standard interface for connecting the fiber optic cable, ensuring a secure and robust connection. The 40Gb/s speed provided by the 01KN821 makes it ideal for high-bandwidth applications such as data center core and aggregation layers, high-performance computing (HPC) interconnects, and high-speed storage area networks (SANs). It enables efficient data transfer and supports the growing demands of modern enterprise and cloud environments, facilitating faster communication between servers, switches, and storage devices.
