## Summary description

The BlueOptics QSFP-40GE-LR4-BO is a fiber optic transceiver module designed for high-speed data transmission. It features a QSFP interface and LC connectors, ensuring compatibility with various networking equipment. Weighing only 20g, it is lightweight and easy to install, making it ideal for data centers and enterprise networks.

## Long description

The BlueOptics QSFP-40GE-LR4-BO is a 40G fiber optic transceiver module with a QSFP interface and LC duplex connectors. Designed for single-mode fiber, it supports high-speed optical transmission for network equipment that accepts QSFP 40GBASE-LR4 modules. The module is compact and lightweight (approximately 20 g) with an aluminium housing, suitable for installation in data center switches, routers and storage systems that support LR4 optics.
Advantages
This QSFP transceiver follows MSA-compliant form factor and LC connector standards to ensure interoperability with a wide range of networking hardware. It supports 40GBASE-LR4 optical links over single-mode fiber, providing long-reach connectivity. The module includes digital diagnostics (DDM/DOM) capability for remote monitoring of supply voltage, laser bias current, transmit power, receive power and temperature when the host hardware supports these functions. The compact aluminium design and low weight simplify handling and installation in dense rack environments.
Suitable for
40 Gigabit Ethernet links in data centers and enterprise networks
Long-reach single-mode fiber connections up to LR4 distance ranges
Interconnects between switches, routers and storage systems that accept QSFP 40GBASE-LR4 optics
Applications requiring optical DOM/DDM monitoring for maintenance and troubleshooting
Key specifications
Form factor: QSFP (Quad Small Form-factor Pluggable)
Data rate: 40 Gbps (aggregated)
Optical standard: 40GBASE-LR4 over single-mode fiber
Connector type: LC duplex
Monitoring: Digital Diagnostics / DOM (MSA SFF-8472 compliant)
Housing material and colour: aluminium
Weight: approx. 0.02 kg
How to use
Install the QSFP-40GE-LR4-BO into a compatible QSFP port on your network device following the device manufacturer's hot-plug instructions. Use LC duplex single-mode patch cords or a suitable breakout assembly for interconnection. Ensure the host equipment supports 40GBASE-LR4 optics and, if you intend to use monitoring features, that the device firmware exposes DDM/DOM parameters. Verify link status and settings in the switch or router management interface after insertion.
Usage recommendations
For reliable long-reach performance, use low-loss single-mode fiber and high-quality LC connectors. Confirm compatibility with your network hardware before deployment and enable digital diagnostics in the host system to monitor optical parameters and support remote troubleshooting.
