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

The BlueOptics QSFP-40G-LR4-20-BC-BO is a 40 Gbit/s fiber optic QSFP transceiver module designed for long-reach single-mode links. It supports a maximum data transfer rate of 40,000 Mbit/s and uses LC fiber connectors to interface with fiber cabling. With a compact QSFP form factor and a lightweight design (approximately 40 g), this module is intended for use in high-speed network equipment requiring 40 GbE links over extended distances.

Advantages

This transceiver provides high-bandwidth performance with support for 40 Gbit/s throughput while maintaining compatibility with QSFP ports. The LR4 variant enables long-distance single-mode transmission up to the specified maximum transfer distance, and the LC connector type ensures broad interoperability with standard duplex single-mode fiber cabling. Its compact QSFP form factor allows installation in switches, routers, or media converters that accept QSFP modules, and the low weight simplifies handling during installation.

How to use

Insert the QSFP transceiver into a compatible QSFP port on network equipment following the equipment manufacturer’s hot-plugging guidelines. Connect duplex single-mode LC fiber patch cords to the transceiver’s LC ports, ensuring correct transmit/receive orientation. Verify link status through the host device management interface and monitor optical parameters if supported. Handle the module by its housing, protect the optical interfaces with dust caps when not in use, and follow standard electrostatic discharge (ESD) precautions during installation and removal.

Recommendations

Use quality single-mode fiber cabling and LC duplex patch cords to achieve the specified maximum transfer distance. Confirm compatibility with the host device’s firmware and QSFP port specifications before deployment. Avoid bending fiber beyond recommended radii and ensure clean connectors to maintain optimal signal integrity.
