## Long description

The BlueOptics SM40G-LR fiber optic transceiver module supports data transfer up to 40000 Mbit/s and uses a QSFP interface for high-density, high-throughput network installations. Housed in a compact silver module and weighing approximately 20 g, it is intended for single-mode fiber links where long-reach optical connectivity is required. The transceiver fits standard QSFP ports and is suitable for integration into switches, routers and servers to extend fiber connectivity in data centers and enterprise networks.
Advantages
The BlueOptics SM40G-LR offers a high maximum data rate of 40 Gbit/s in a QSFP form factor, enabling four-lane optical links in a single module. Its compact, lightweight silver housing simplifies installation in dense rack environments and helps maintain airflow. Designed for single-mode fiber, the module supports long-reach connections and reliable optical performance for backbone and aggregation links. The QSFP interface ensures compatibility with equipment that accepts QSFP transceivers and supports hot-pluggable installation.
