## Summary description

The BlueOptics QSFP+LR4 network transceiver module supports a maximum data transfer rate of 40000 Mbit/s. It features a QSFP interface and is designed for fiber optic connections. The module is lightweight at 20 g and comes in a silver color. Ideal for high-speed data transmission over long distances.

## Long description

The BlueOptics QSFP+LR4 40000 Mbit/s transceiver module is a fiber-optic QSFP interface module designed for long-reach, high-bandwidth network links. It supports an aggregate data rate of up to 40 Gbit/s and is intended for installations where reliable, high-speed optical connectivity is required. The module is compact and lightweight, with a silver housing that fits standard QSFP ports in switches, routers and optical equipment.
Advantages
This QSFP+LR4 module provides high-capacity transmission over fiber with a single, standardized QSFP interface, enabling 40 Gbit/s links without additional breakout hardware. Its lightweight construction simplifies handling and installation in dense rack environments, while the silver metal housing offers mechanical durability and electromagnetic shielding. The module is compatible with systems that support QSFP form-factor transceivers and is engineered for stable long-distance optical links.
Suitable for
 40 Gbit/s uplinks between switches and data center aggregation points
 Long-reach optical connections in campus or metro networks
 Interconnects between optical transport equipment and routers
 High-bandwidth links in server farms and virtualization infrastructures
Key specifications
 Interface type: QSFP (Quad Small Form-Factor Pluggable)
 Maximum data transfer rate: 40000 Mbit/s (40 Gbit/s)
 Transmission medium: fiber optic (LR4 long reach)
 Form factor: QSFP+ compatible
 Weight: 0.02 kg
 Colour: silver housing
How to use
Insert the module into a compatible QSFP port on the switch or optical device until it seats firmly; use the release latch to remove it when needed. Connect appropriate single-mode fiber patch cords to the module's optical interface following the equipment manufacturer's guidelines for connector type and polarity. Ensure the host device firmware and port configuration support 40 Gbit/s operation and configure link settings as required by your network design. Observe standard electrostatic discharge (ESD) precautions during handling and avoid touching optical interfaces.
Usage recommendations
Use single-mode OS2 fiber and factory-tested LC or MPO patch cords rated for LR4 applications to achieve specified long-reach performance. Verify link budget and optical power levels with appropriate test equipment after installation. For dense deployments, plan airflow and port allocation to maintain thermal limits and consult system compatibility lists to ensure interoperability.
