QSFP-transceivermodule BlueOptics QSFP-40G-PLR4-QU-BO 40000 Mbit/s 1310 nm

The BlueOptics QSFP-40G-PLR4-QU-BO is a QSFP fiber-optic transceiver module engineered for 40 Gbit/s optical links over single-mode fiber. Operating at a nominal wavelength of 1310 nm, the module supports high-bandwidth connections up to 2000 m and uses an MPO/MTP-style QSFP interface for integration into compatible networking equipment. Encased in a durable metal housing and weighing approximately 50 g, it is intended for use in data center and high-performance networking environments that require stable 40GBASE-PLR4-class transmission.

Advantages

The module offers a compact QSFP form factor that consolidates multiple high-speed channels into a single pluggable unit, simplifying port density and cabling in switches and routers. Its metal enclosure provides mechanical robustness and EMI shielding, while support for digital diagnostic monitoring (DDM/DOM) enables real-time parameter reporting such as supply voltage, optical power and temperature when used in hardware that exposes these diagnostics. Compatibility with MSA QSFP standards and MPO/MTP connectivity ensures interoperability with a wide range of single-mode fiber patching solutions.

How to use

Install the transceiver into a compatible QSFP port on a switch, router or other network device that supports 40GBASE-PLR4 QSFP modules. Use an appropriate single-mode MPO/MTP patch cable or patch panel to connect the optical interface to the remote transceiver or fiber infrastructure. Ensure the host device firmware and drivers accept third-party QSFP modules if applicable and verify link parameters after insertion. If the platform supports DDM/DOM, check the diagnostic values to confirm correct optical power levels, supply voltage and temperature.

Recommendations

Mount and remove the module using the device manufacturer’s recommended procedure to avoid damaging the QSFP cage or the fiber connector. Clean fiber endfaces before mating and use dust caps when the module is unused. Verify compatibility with the target hardware and confirm that DDM/DOM is supported by the host to access diagnostic information. For optimal range and performance, pair the module with quality single-mode fiber and MPO/MTP cabling rated for 40G applications.
