QSFP-transceivermodule BlueOptics QSFP-40G-LR4-UQ-BO 40 Mbit/s

The BlueOptics QSFP-40G-LR4-UQ-BO is a fiber optic QSFP transceiver module designed for 40 Mbit/s data transfer. It features a QSFP interface, metal housing and operates at an input voltage of 3.3 V. With a compact weight of 20 g and a mean time between failures (MTBF) of 1,000,000 hours, the module is intended for high-availability network applications using single-mode fiber and LC duplex connections where a QSFP form factor is required.

Advantages

The module provides a standardized QSFP interface for straightforward integration into compatible network hardware. Its metal housing supports mechanical durability and thermal dissipation while the specified MTBF indicates long operational life. The transceiver supports single-mode fiber links and includes features common to LR4 optics, enabling transmission over extended single-mode fiber runs when used with appropriate fiber and supporting equipment.

Suitable for

• High-speed links between switches and routers supporting QSFP modules
• Data center interconnects and aggregation links over single-mode fiber
• Storage area networks and fibre channel applications that accept QSFP optics
• Network equipment replacement or upgrades where a QSFP form factor is required

Key specifications

• Interface type: QSFP
• Maximum data transfer rate: 40 Mbit/s
• Connector: LC duplex (for single‑mode fiber)
• Operating input voltage: 3.3 V
• Housing: metal
• Weight: 0.02 kg
• Reliability: MTBF 1,000,000 hours

How to use

Install the BlueOptics QSFP-40G-LR4-UQ-BO into a QSFP-compatible port on supported network equipment while the device is powered down or following the host manufacturer’s hot-plugging procedure. Connect LC duplex single-mode fiber patch cords to the module’s connectors, ensuring correct transmit/receive orientation. Verify that the host hardware and firmware support the module and the LR4 transmission profile before enabling the port. Monitor link status and diagnostics through the host system as applicable.

Recommendations

Use high-quality single-mode LC duplex patch cords and, where available, enable digital diagnostic monitoring (DDM/DOM) on the host to track voltage, laser bias, optical power and temperature. Confirm compatibility with the specific network device model and firmware version prior to deployment and follow ESD precautions and manufacturer guidelines during handling and installation.
