## Long description

The BlueOptics QSFP-40G-LR4-LS-BO is a fiber optic QSFP transceiver module designed for high-speed optical data transfer. It supports a maximum data rate of 40 Mbit/s over single-mode fiber and is built in a compact metal housing that provides mechanical durability while keeping the module weight to approximately 20 g. The transceiver follows QSFP form-factor conventions and is intended for use in networking equipment that accepts QSFP optical modules.
Advantages
The metal casing offers physical protection and contributes to long operational reliability with a manufacturer-stated mean time between failures (MTBF) of 1,000,000 hours. The module's QSFP interface supports hot-pluggable installation and standard optical connections, simplifying integration into switches, routers, and other network hardware. Its lightweight construction and standardized form factor make handling and replacement straightforward in rack-mounted equipment.
Suitable for
High-speed Ethernet links up to 40 Mbit/s over single-mode fiber
Interconnects between switches, routers, and storage systems that support QSFP modules
Long-reach optical links where QSFP LR4-style transceivers are required
Key specifications
Interface type: QSFP
Maximum data transfer rate: 40 Mbit/s
Transmission medium: single-mode fiber (LC duplex expected for LR4-style modules)
Housing: metal casing
Weight: 0.02 kg
MTBF: 1,000,000 hours (manufacturer-stated)
How to use
Install the BlueOptics QSFP-40G-LR4-LS-BO into a compatible QSFP port on your network device while the device is powered on or following the equipment vendor's hot-swap guidance. Connect single-mode fiber patch cords with LC duplex connectors to the module's optical ports, ensuring correct transmit/receive orientation. Confirm link status and negotiated speed via the host device management interface. If supported by the host, enable and read Digital Diagnostics Monitoring (DDM/DOM) features for real-time metrics such as supply voltage, optical power and temperature.
Usage recommendations
Use this transceiver with single-mode fiber and LC duplex patch cords matched to LR4 optical specifications. Verify host compatibility with QSFP modules and DDM/DOM support before deployment, and follow ESD precautions and vendor guidelines during handling and installation to maintain module reliability.
