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

The BlueOptics QSFP-40G-LR4-20-QN-BO is a QSFP transceiver module engineered for 40 Gbit/s fiber optic links. Designed for long-range single-mode connections, this compact module supports high-bandwidth transport over distances up to 20,000 m and uses LC fiber connectors. With a small form factor and a weight of approximately 40 g, it integrates into QSFP-capable switches and routers to extend backbone and aggregation network segments where reliable 40G connectivity is required.

Advantages

This transceiver delivers a stable 40,000 Mbit/s transmission speed and is optimized for long-distance single-mode fiber runs, reducing the need for intermediate repeaters. The QSFP interface provides a standardized connection for high-density networking equipment, and LC connectors enable compatibility with common fiber cabling. Its compact size and low weight simplify installation and minimize space usage in dense rack environments.

Key specifications

How to use

Insert the QSFP transceiver into a compatible QSFP port on a switch or router, ensuring the module is correctly oriented and fully seated. Connect LC-terminated single-mode fiber patch cords to the module's LC ports, observing proper polarity. After connection, verify link status and interface configuration on the networking device; adjust transceiver or interface settings as required by the equipment vendor. Handle the module using ESD precautions and keep protective dust caps on fiber connectors when not in use.

Recommendations

Use single-mode fiber cabling rated for long-distance 40G links and verify compatibility with host equipment before deployment. Maintain proper fiber cleanliness and follow ESD-safe handling procedures. For optimal performance over maximum distances, consult link budget calculations and the network equipment vendor's guidelines.
