Glasvezel-transceivermodule BlueOptics TN-QSFP-40G-LR4-BO 40000 Mbit/s QSFP

The BlueOptics TN-QSFP-40G-LR4-BO is a fiber optic transceiver module designed for 40GBASE-LR4 single-mode links. With a QSFP form factor and support for data transfer rates up to 40000 Mbit/s, this compact 20 g transceiver provides a CE-certified solution for high-speed Ethernet and related optical networking applications. The module uses LC Duplex connectivity and CWDM-based transmit and receive channels to carry signals over single-mode fiber for long-reach connections.

Advantages

The module follows MSA-compliant QSFP mechanical and electrical specifications to ensure interoperability with a broad range of network equipment that supports LR4 optics. Its lightweight silver housing simplifies installation and rack-side handling. Built to work with single-mode fiber and LC Duplex connectors, the transceiver supports high-bandwidth links with reduced susceptibility to electromagnetic interference common to copper links. Where supported by host hardware, the module provides digital diagnostic monitoring functions for real-time information on supply voltage, laser bias current, transmit power, receive power and temperature.

Key specifications

How to use

Install the transceiver into a compatible QSFP port on a switch, router or appliance only when the host device is powered according to the vendor instructions. Connect LC Duplex single-mode patch cords to the module’s LC ports, ensuring correct transmit/receive orientation and that cable polarity and fiber type match the link design. Verify that the host system supports 40GBASE-LR4 optics and, if required, enable any interface settings in the device software. If the host supports digital diagnostics (DDM/DOM), monitor the reported parameters for link health and operating conditions.

Recommendations

Use this module with certified single-mode LC Duplex patch cables and appropriate patch panels to achieve intended link distance and performance. Confirm compatibility with the target hardware and firmware; test samples in the actual network environment before large-scale deployment. Avoid bending the fiber beyond manufacturer-specified radii and follow ESD precautions when handling the transceiver.
