## Summary description

The BlueOptics ET6401-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 housing and weighs only 20 g, making it lightweight and durable. This transceiver is ideal for network applications requiring reliable connectivity and high performance.

## Long description

The BlueOptics ET6401-LR4-BO QSFP 10000 m is a 40GBASE-LR4-compatible fiber optic transceiver module designed for long-distance single-mode links up to 10,000 meters. Housed in lightweight aluminium and weighing just 20 g, this QSFP transceiver uses LC duplex connectivity and supports 40 Gbps optical data transmission with CWDM-based transmitter and receiver channels. It is built to meet MSA QSFP form-factor standards and to be used in network hardware that supports LR4 QSFP optics.
Advantages
The module provides long-reach optical connectivity with low electromagnetic interference susceptibility inherent to single-mode fiber links. Built according to MSA standards, it features CWDM optics for reliable wavelength multiplexing and supports Digital Diagnostics Monitoring (DDM/DOM) for real-time parameters such as supply voltage, laser bias, transmit/receive power and temperature. The aluminium housing offers mechanical durability while keeping weight minimal for dense installations.
Suitable for
 40 Gbps Ethernet connections over single-mode fiber
 Fibre Channel over Ethernet and SDH/SONET high-speed links
 Long-distance uplinks between switches, routers and data center equipment up to 10 km
 Replacement or compatible upgrade for LR4 QSFP-supported hardware platforms
Key specifications
 Form factor: QSFP (quad small form-factor pluggable)
 Data rate: up to 40 Gbps aggregate
 Optical reach: up to 10,000 m (single-mode fiber)
 Connector type: LC duplex
 Optical technology: CWDM transmitter and receiver
 Housing material and colour: aluminium
 Weight: 0.02 kg
 Supports Digital Diagnostics Monitoring (DDM/DOM) compliant with SFF-8472
How to use
Insert the QSFP transceiver into a compatible QSFP port on the host device while the device is powered down or following the host vendor’s hot-plug procedure. Connect LC duplex single-mode fiber patch cords to the transceiver’s LC ports, observing transmit/receive orientation. Verify the host device recognizes the module and, if available, enable or read out DDM/DOM parameters to monitor link health. Use appropriate fiber patch panels or direct connections to achieve the specified reach and performance.
Usage recommendations
Ensure the host hardware and software explicitly support LR4 QSFP modules and DDM/DOM if diagnostics are required. Use single-mode fiber and high-quality LC duplex patch cords, maintain clean connectors, and verify link budget for runs approaching 10 km. For interoperability, test the module in your specific platform before large-scale deployment.
