Fiber optic transceiver module BlueOptics TN-QSFP-40G-IR4-BO 40000 Mbit/s QSFP

The BlueOptics TN-QSFP-40G-IR4-BO is a 40 Gbit/s fiber optic transceiver module with a QSFP interface designed for single-mode optical links. Housed in a silver metal casing, the module operates at 3.3 V input and supports high-speed transmissions over LC Duplex connections. It is built to meet MSA QSFP form-factor standards and is compatible with network hardware that accepts QSFP 40G modules, offering long-reach performance suitable for Ethernet and other high-speed protocols.

Advantages

This transceiver provides 40,000 Mbit/s throughput in a compact QSFP package and uses single-mode optics with CWDM to enable long-reach links. Metal housing improves mechanical durability and thermal performance for reliable operation in rack-mounted equipment. The module supports digital diagnostics (DDM/DOM) for real-time monitoring of supply voltage, laser bias current, transmit power, receive power and temperature, which simplifies maintenance and troubleshooting. It is manufactured to MSA standards and uses industry-grade optical and electronic components for extended operational life.

How to use

Install the BlueOptics TN-QSFP-40G-IR4-BO into a compatible QSFP port on a switch, router or other networking device while the host device is powered off or following the vendor’s hot-plug instructions. Connect LC Duplex single-mode fiber patch cords to the module ensuring correct transmit/receive orientation. Verify that the host device recognizes the module and, if available, enable or read out DDM/DOM data to confirm proper operating parameters. Ensure the local link budget and fiber attenuation are within the module’s specifications for the required reach.

Recommendations

Use factory-quality single-mode fiber and high-quality LC patch cords or patch panels to achieve optimal range and signal integrity. Confirm hardware compatibility with your switch or router vendor and update device firmware if necessary to ensure full QSFP support. Monitor DDM/DOM values periodically to detect degradation in transmit power, receive power or temperature. Maintain a clean environment for fiber connectors and follow standard ESD precautions when handling the module.
