## Summary description

The BlueOptics 40GBASE-LR4-BO is a QSFP fiber optic transceiver module designed for high-speed data transmission over long distances up to 10000 m. It features an aluminum body and weighs only 20 g, making it lightweight and durable. Ideal for data centers and enterprise networks requiring reliable connectivity.

## Long description

The BlueOptics 40GBASE-LR4-BO is a QSFP fiber optic transceiver module designed for long-distance, high-speed data transmission up to 10,000 m over single-mode fiber. Housed in an aluminium body and weighing 20 g, the module follows MSA-compatible QSFP form factor and provides a 40 Gbps optical interface with LC duplex connectivity for use in data centers and enterprise network equipment that support 40GBASE-LR4 optics.
Advantages
The module offers a compact, lightweight aluminium housing for mechanical stability and heat dissipation while keeping port density high. It is built to industry MSA standards for QSFP optics and is compatible with devices that accept 40GBASE-LR4 QSFP modules. The transceiver supports long-reach single-mode links and integrates optical components intended to deliver stable operation and extended service life. A Digital Diagnostic Monitoring (DDM/DOM) interface is available when supported by the host hardware to report real-time parameters such as supply voltage, laser bias, optical output/input power and temperature.
Suitable for
Data center uplinks and aggregation switches
Enterprise core and distribution layer connections
High-performance computing clusters and storage interconnects
Long-reach optical links over single-mode fiber up to 10 km
Key specifications
Interface type: QSFP (Quad Small Form-factor Pluggable)
Nominal data rate: 40 Gbps (40GBASE-LR4)
Maximum reach: 10,000 meters over single-mode fiber
Connector type: LC duplex
Housing material and colour: aluminium, aluminium colour
Weight: 0.02 kg
Support for Digital Diagnostic Monitoring (DDM/DOM) when enabled by host device
How to use
Install the QSFP transceiver into a compatible QSFP slot on the switch, router or other network device, ensuring the host device supports 40GBASE-LR4 optics. Connect the LC duplex single-mode fiber cable to the module, observing correct transmit/receive alignment. Configure the host interface according to your network equipment procedures; if the host supports DDM/DOM, enable or query diagnostics via the device management interface to monitor operational parameters. Follow hot-plug precautions described by the hardware vendor when inserting or removing the module.
Usage recommendations
Use quality single-mode LC duplex patch cords and, where applicable, single-mode patch panels to preserve optical performance. Verify host compatibility with 40GBASE-LR4 QSFP modules and ensure firmware or driver requirements are met to enable full functionality and DDM/DOM reporting.
