QSFP transceiver module BlueOptics QSFP-40G-LR4-20-MT-BO 40000 Mbit/s

The BlueOptics QSFP-40G-LR4-20-MT-BO is a fiber optic QSFP transceiver module engineered for high-speed 40 Gbit/s data links. Designed for long-range single-mode transmission, this compact module supports reliable 40000 Mbit/s throughput over distances up to 20,000 m and uses LC fiber connectors. With a lightweight design (approximately 40 g) and a QSFP form factor, it integrates into compatible networking equipment to extend high-bandwidth connections in data center interconnects and telecom networks.

Advantages

The transceiver provides stable, high-capacity transmission suitable for long-distance links, combining the QSFP interface with standard LC connectors for broad compatibility. Its compact QSFP form factor enables dense port population in switches and routers while keeping power and space requirements low. The module’s specification for 40 Gbit/s throughput and single-mode fiber operation ensures consistent performance for latency-sensitive and high-bandwidth applications.

How to use

Install the BlueOptics QSFP-40G-LR4-20-MT-BO into a compatible QSFP port on your switch, router, or transceiver cage following the equipment manufacturer’s hot-plug and safety instructions. Connect single-mode fiber cables terminated with LC connectors to the module’s ports, ensuring correct polarity and secure connections. After physical installation, verify link status and configure port settings on the network device as required for 40 Gbit/s operation and any necessary optical diagnostics.

Recommendations

Ensure compatibility of the host device with QSFP modules and confirm single-mode fiber infrastructure for long-range operation. Use quality LC-terminated cables, check connector cleanliness before mating, and monitor link parameters through the switch or router for optimal performance and early detection of signal degradation.
