QSFP-transceivermodule BlueOptics QSFP-40G-LR4-MA-BO 40 Mbit/s

The BlueOptics QSFP-40G-LR4-MA-BO is a fiber optic QSFP transceiver module engineered for 40 Mbit/s optical links over single-mode fiber. The module uses a QSFP interface in a metal housing, operates at 3.3 V input voltage and weighs approximately 20 g. Designed to meet MSA QSFP mechanical and electrical standards, it supports LC duplex connections and digital diagnostic monitoring for remote maintenance and status reporting.

Advantages

This transceiver offers a compact QSFP form factor with a metal housing for mechanical robustness and thermal dissipation. It provides long operational life with an MTBF of 1,000,000 hours and minimal weight for easy installation and handling. Compliance with MSA standards ensures interoperability with compatible networking hardware while Digital Diagnostics Monitoring (DDM/DOM) enables real-time access to supply voltage, laser bias current, transmit power, receive power and temperature for simplified troubleshooting.

Suitable for

• High-speed Ethernet and Fibre Channel over Ethernet applications
• Single-mode fiber links up to several kilometers where LC duplex connectors are used
• Switches, routers, storage systems and other QSFP-capable network equipment
• Environments requiring remote optical link diagnostics and monitoring

How to use

Install the BlueOptics QSFP-40G-LR4-MA-BO into a compatible QSFP slot following the host device manufacturer’s hot-swap and insertion procedures. Connect LC duplex single-mode fiber patch cords to the transmit and receive ports, ensuring correct orientation for Tx/Rx pairs. Verify the host hardware supports the transceiver’s DDM/DOM features if remote diagnostics are required. Power the host device with the recommended supply and confirm link status through the device interface or management software.

Recommendations

Use quality single-mode LC duplex patch cords and compliant patch panels to achieve optimal range and signal quality. Ensure the host system firmware supports MSA-compatible QSFP modules and DDM/DOM functions to utilize diagnostic capabilities. Avoid excessive mechanical stress on connectors and follow proper electrostatic discharge (ESD) precautions during handling and installation.
