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

The BlueOptics QSFP-40G-LR4-20-NK-BO is a QSFP fiber optic transceiver module engineered for high-speed 40 Gbit/s data links. Designed for use in data centers and carrier-class networks, this compact module supports long-reach optical connections up to 20,000 meters over single-mode fiber and uses LC connectors. The transceiver weighs approximately 40 g and fits standard QSFP ports for easy installation in compatible switches, routers and optical equipment.

Advantages

This module provides a stable 40 Gbit/s transmission rate suitable for aggregation and backbone links. Its LR4 wavelength-division multiplexing design enables long-distance connectivity without additional signal conversion. The QSFP form factor delivers high port density while maintaining low weight and compact dimensions, and LC optical interfaces ensure wide compatibility with single-mode fiber patching and cabling systems.

How to use

Insert the BlueOptics QSFP-40G-LR4-20-NK-BO into a compatible QSFP port on your switch or router until it latches. Connect single-mode LC fiber patch cables to the module’s LC ports, ensuring correct polarity and clean end faces. Verify link status and module recognition through the host device’s management interface and monitor signal quality and error counters to confirm proper operation.

Recommendations

Use certified single-mode fiber and LC patch cords and perform end-face inspection before connection. Ensure that the host device supports QSFP LR4 modules and that firmware or driver compatibility is confirmed. For long-span deployments, follow industry guidelines for fiber attenuation and dispersion budgeting.
