QSFP Transceiver Module BlueOptics QSFP-40G-LR4-20-VA-BO 40000 Mbit/s

The BlueOptics QSFP-40G-LR4-20-VA-BO is a QSFP-format fiber optic transceiver module engineered for 40 Gbit/s links. Designed for single-mode fiber connections with LC connectors, the module supports long-distance links and fits standard QSFP cages and ports. With a lightweight metal housing of approximately 40 g and industry-compatible QSFP form factor, it is intended for data center uplinks, aggregation, and high-speed network interconnects where reliable 40 Gbit/s optical transport is required.

Advantages

This transceiver provides high-capacity 40 Gbit/s throughput while maintaining a compact QSFP footprint, enabling dense port deployment. The LR4 design supports extended single-mode fiber spans up to 20 km, allowing flexible network topology and long-reach connectivity between aggregation points. The module's LC connector interface and standard electrical/optical characteristics make it interoperable with common switches and routers that accept QSFP LR4 optics.

Key specifications

How to use

Insert the QSFP transceiver into a compatible QSFP port on a switch or router until it seats securely and the latch engages. Connect single-mode fiber patch cords with LC connectors to the transceiver’s receptacles, ensuring correct transmit/receive orientation. Verify link status in the host device interface and configure the port for 40 Gbit/s operation if required. Follow the equipment manufacturer’s hot-plug and ESD precautions when installing or removing the module.

Recommendations

Use single-mode OS2 fiber for distances approaching the module’s maximum range and keep patching short and well-managed in data centers to reduce insertion loss. Ensure compatibility with the host device’s QSFP LR4 specifications and check optical budgets when integrating into existing networks. Store spare modules in anti-static packaging and avoid exposure to extreme temperatures or contamination of connector endfaces.
