Fiber optic transceiver module BlueOptics SM40G-LR 40000 Mbit/s QSFP

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.

Key specifications

How to use

Install the BlueOptics SM40G-LR into a compatible QSFP port on a switch, router or server following standard hot-pluggable transceiver procedures. Ensure the system is powered according to the host device instructions before insertion or removal and observe electrostatic discharge precautions. Connect appropriate single-mode fiber cabling and verify link status and operational parameters via the host device management interface. Configure device interfaces and any required VLANs or link aggregation settings as per network design.

Recommendations

Use single-mode fiber with connectors and patch panels rated for long-reach links. Verify compatibility with the host equipment's QSFP specifications and firmware; check optical power budgets and link budget calculations when planning distances. Handle the transceiver by its housing, keep optical ports protected with dust caps when not connected, and store modules in a dry, static-free environment.
