QSFP transceivermodule BlueOptics QSFP-40G-LR4-20-CO-BO 40000 Mbit/s

The BlueOptics QSFP-40G-LR4-20-CO-BO is a QSFP form-factor fiber optic transceiver module engineered for 40 Gbit/s data links and long-range optical connections. Designed for use in optical networking equipment, the module supports LC fiber connectors and a maximum transfer distance of up to 20,000 meters, enabling high-capacity transmission between switches, routers and aggregation points. With a compact QSFP interface and a lightweight 40 g build, this transceiver fits into standard QSFP ports and is suitable for data center uplinks, metro and long-haul segments where reliable single-mode fiber connectivity is required.

Advantages

This transceiver provides a stable 40,000 Mbit/s throughput with long-distance capability up to 20 km, supporting cost-effective consolidation of high-bandwidth links. The QSFP form factor offers high port density and hot-pluggable convenience for easy deployment and maintenance. LC fiber termination ensures compatibility with common single-mode cabling and existing infrastructure. The lightweight construction reduces mechanical strain on equipment while maintaining standard optical performance.

How to use

Install the BlueOptics QSFP-40G-LR4-20-CO-BO into a compatible QSFP port on networking equipment following the vendor's hot-plug procedures. Connect single-mode fiber with LC connectors, ensuring proper alignment and clean end-faces to minimize insertion loss. Configure the network device for 40 Gbit/s operation and verify link status through the switch or router management interface. Monitor signal quality and optical power levels where possible to confirm reliable operation across the intended distance.

Recommendations

For optimal performance, use single-mode fiber rated for long-reach transmission and maintain clean LC connectors. Verify transceiver compatibility with the host device and firmware, and follow optical power budget calculations when planning links approaching the 20 km maximum distance.
