QSFP Transceiver Module BlueOptics QSFP-40G-LR4L-TM-BO 40000 Mbit/s

The BlueOptics QSFP-40G-LR4L-TM-BO is a 40 Gbit/s fiber optic QSFP transceiver designed for single-mode optical links. Housed in a compact metal enclosure and finished in silver, this QSFP module supports line rates up to 40000 Mbit/s and is specified for optical transmission distances up to 2000 m over single-mode fiber. The module implements 40GBASE-LR4L functionality with LC duplex connectivity and is compatible with MSA QSFP form-factor interfaces used in switches, routers and other network equipment.

Advantages

The transceiver delivers high-bandwidth transmission with a metal housing that helps dissipate heat and provides mechanical robustness. Transmode-compatible design and adherence to MSA standards enable broad interoperability with platforms that support 40GBASE-LR4L QSFP modules. Integrated optical transmitters and receivers with CWDM allow simultaneous transmit/receive operation over single-mode fiber, while the compact QSFP form factor conserves port density in racks and chassis.

How to use

Install the QSFP module into a compatible QSFP port on your switch, router or other network device while the host is powered according to the device manufacturer’s recommended procedure. Connect LC duplex single-mode fiber patch cords to the module’s LC ports, ensuring correct transmit/receive orientation. Verify link status and negotiate 40G operation through the host device management interface. If the host supports digital diagnostics, enable the module’s monitoring functions per the host documentation to read real-time parameters like supply voltage, transmit power and temperature.

Recommendations

Use single-mode LC duplex patch cords rated for the target distance and avoid tight bends or stress on fiber runs. Confirm host compatibility and DDM/DOM support before deployment, and follow ESD handling practices when inserting or removing the QSFP module.
