QSFP transceiver modul BlueOptics QSFP-40G-LR4-20-F5-BO 40000 Mbit/s

The BlueOptics QSFP-40G-LR4-20-F5-BO is a QSFP fiber optic transceiver module engineered for high-speed long-range data transmission. Supporting up to 40,000 Mbit/s, this compact module uses LC connectors and is suitable for insertion into equipment with QSFP ports to extend network links over single-mode fiber. With a lightweight 40 g housing and optical design for LR4 performance, it is intended for network backbones, data center interconnects and carrier links requiring stable, long-distance connectivity.

Advantages

This QSFP transceiver combines a high maximum data transfer rate with LR4 optical reach, enabling reliable links up to 20,000 m over single-mode fiber. The LC connector interface ensures compatibility with standard fiber patching infrastructure. Its QSFP form factor supports high-density port deployment in switches and routers, while the low weight and compact size simplify handling and installation. The module is designed for straightforward integration into existing optical networks without specialized mechanical modifications.

How to use

Install the BlueOptics QSFP-40G-LR4-20-F5-BO into a compatible QSFP port on your switch, router or transponder following the host device manufacturer's hot-plug procedures. Connect LC-terminated single-mode fiber patch cords to the module's LC ports, ensure proper fiber polarity and secure all connections. Configure the host device for a 40 Gbit/s optical interface and verify link status and signal parameters via the management interface. Monitor optical power and error counters during initial operation to confirm stable link performance.

Recommendations

Use single-mode fiber certified for long-reach LR4 applications and maintain clean LC connector endfaces. Verify compatibility with your networking equipment's QSFP modules list and ensure firmware or driver updates if required. For best results, perform optical loss budget calculations for links approaching the 20 km range and use appropriate dispersion management where necessary.
