Transceiver QSFP BlueOptics QSFP-40G-LR4-MV-BO fibra ottica LC

The BlueOptics QSFP-40G-LR4-MV-BO is a 40GBASE-LR4 fiber optic transceiver module with a QSFP interface and LC duplex connector, designed for long-range single-mode fiber links up to 10 km. The aluminum-coloured module weighs approximately 20 g and follows MSA form-factor specifications to ensure interoperability with compatible network equipment. It supports high-speed applications such as Ethernet, Fibre Channel over Ethernet and SDH/SONET up to 40 Gbit/s and includes CWDM-based transmit and receive channels for multi-wavelength operation.

Advantages

This transceiver offers long-range transmission on single-mode fiber with a compact QSFP form factor for high-density installations. Manufactured to MSA standards and using proven optical components, it is engineered for compatibility with major hardware platforms that support the original LR4 QSFP specification. Integrated digital diagnostics (DDM/DOM) enable real-time monitoring of supply voltage, laser bias current, transmit power, received power and temperature to simplify maintenance and troubleshooting.

Suitable for

• Data center uplinks and spine connections
• Enterprise backbone and aggregation links
• High-speed storage networking and SAN interconnects
• Long-distance campus and metro fiber links up to 10 km

How to use

Install the QSFP transceiver into a compatible QSFP cage on your switch, router or other network device that supports LR4 QSFP modules. Connect LC duplex single-mode patch cords to the transceiver ports, ensuring correct transmit/receive orientation. Verify link status and, if supported by your hardware, access digital diagnostics to monitor operating parameters. Follow standard ESD precautions when handling the module and keep protective dust caps on unused ports until connection.

Recommendations

For optimal performance use single-mode fiber and high-quality LC patch cords rated for LR4 transmission, ensure the host device firmware supports LR4 QSFP modules and enable DDM/DOM monitoring where available to maintain link reliability over time.
