QSFP Transceiver Module BlueOptics QSFP-40G-LR4-EE-BO 40 Mbit/s

The BlueOptics QSFP-40G-LR4-EE-BO is a QSFP fiber-optic transceiver module designed for single-mode links with a maximum data transfer rate of 40 Mbit/s. The module uses LC duplex connectors and follows MSA QSFP form-factor definitions to ensure mechanical and electrical interoperability with compatible switches, routers and storage systems. With an MTBF of 1,000,000 hours and a compact 20 g weight, this transceiver is intended for high-availability network environments requiring long-reach optical connections.

Advantages

This transceiver implements 40GBASE-LR4 functionality with CWDM-based transmit and receive channels for optical signal multiplexing over single-mode fiber. Full MSA compliance ensures plug-and-play compatibility across a wide range of QSFP-capable hardware. Built with industry-grade optical and electronic components, it supports long service life and reduced maintenance intervals. Digital Diagnostics Monitoring (DDM/DOM) is available for real-time monitoring of supply voltage, laser bias current, transmit power, receive power and module temperature where supported by the host device.

Suitable for

• 40G Ethernet links between switches and routers
• Fibre Channel over Ethernet (FCoE) and high-speed storage interconnects
• Long-reach single-mode connections up to several kilometres in data center or campus networks

How to use

Insert the QSFP transceiver into a compatible QSFP port on the host device following the vendor’s hot-plug and electrostatic discharge (ESD) guidelines. Connect LC duplex single-mode fiber patch cords to the module’s connectors, ensuring correct transmit/receive orientation and proper cable routing to avoid sharp bends. Verify link negotiation and module status through the host device management interface; enable DDM/DOM monitoring if supported to observe diagnostic parameters. For long-distance links, use appropriate single-mode fiber and ensure end-to-end compatibility of fiber type and patch panels.

Recommendations

Confirm firmware and hardware compatibility with the host platform before deployment. Use quality single-mode LC patch cords and keep connector endfaces clean to maintain signal integrity. Rely on DDM/DOM readings for preventive maintenance and replace modules if diagnostic values fall outside vendor-recommended ranges.
